In the case of FAO Area 18, the member countries did not do their job. Thus, catches for the north of Siberia were not reported to the FAO by the USSR and later Russia (which can perhaps be forgiven since the USSR was not a member, and Russia joined the FAO only in 2006). Similarly, Canada’s catches from its Arctic waters were desultorily reported to the FAO. We reported on this for both USSR/Russia and Canada in Fisheries Centre Research Reports, 15(2), published in 2007. The present report, which covers the fishery of arctic Alaska, thus completes our coverage of the Amerasian Arctic, i.e., of FAO Area 18, for which the total catch, as reconstructed by members of the Sea Around Us Project from 1950 to 2005, is over 50 times that reported by FAO. As is here illustrated for Alaska, this is because the statistical reporting systems at the national (and hence international) level for fisheries on Russia, the USA and Canada do not pay any attention to their small- scale fisheries, even when these provide all the fish consumed in vast areas. In this, unfortunately, Russia, the USA and Canada do not differ much from other countries, which all tend to underestimate their small- scale fisheries catches. But more could have been expected, given that these three countries have the resources, one would think, to document one of the major food-producing sectors of the economy along their Arctic coasts. The present report also highlights the USA-specific problem of missing data as they relate to state-level jurisdiction, as fisheries data collected and reported by the State of Alaska from their 3 nautical mile jurisdiction are not incorporated into national catch reports. Be that as it may, these catch time series should now become important baselines, e.g., for assessing gains and losses due to the warming now raging in the Arctic, which will not fail to impact on fisheries. This is also the reason why the documentation of the bottom-up process used to arrive at the catch data presented therein is given in such great details. This report is based on work funded by the Lenfest Oceans Program (www.lenfestocean.org), and we thank Ms Margaret Bowman for having understood the need to establish a historic baseline for fisheries which may change radically in the next decades, as the ice of the Arctic recedes and its waters become accessible to industrial fishing fleets. These fleets have wreaked havoc on the fish stocks and ecosystems further south. Let us hope that they do not get to undermine the fisheries documented here. Daniel Pauly, Director UBC Fisheries Centre October 2008 Marine fisheries catches in arctic Alaska, Booth & Zeller 2 MARINE FISHERIES CATCHES IN ARCTIC ALASKA1 Shawn Booth and Dirk Zeller Fisheries Centre, University of British Columbia, Vancouver, BC V6T 1Z4 e-mail: s.booth@fisheries.ubc.ca; d.zeller@fisheries.ubc.ca ABSTRACT The Food and Agriculture Organization of the United Nations (FAO) provides global data on fisheries catches based on reports by member countries. Interestingly, for FAO Statistical Area 18 (Arctic), the USA reports no fish catches to the global community. In Alaska, it is the communities found north of Cape Prince of Wales that fall within FAO area 18. However, the State of Alaska’s Department of Fish and Game has collected time series of commercial data, and undertakes community fisheries subsistence studies that are temporally and spatially intermittent. At the regional level, the National Oceanic and Atmospheric Administration (NOAA, Alaska) do not report on either of these fisheries, as they take place within state waters. The Sea Around Us Project, at the University of British Columbia’s Fisheries Centre, undertakes catch reconstructions to account for discrepancies between globally reported and likely total catches. Our catch reconstruction includes both subsistence and commercial fisheries of marine and anadromous species from 1950-2006 for 15 coastal and near-coastal communities in arctic Alaska. Total catches over this time period were estimated to be 89,000 tonnes (196.2 million pounds), with subsistence catches contributing 54 % (48,200 tonnes or 106.4 million pounds), and commercial catches estimated at over 40,700 tonnes (89.8 million pounds). Subsistence catches averaged 847 tonnes·year-1 (1.8 million pounds·year-1, range: 589-1,139 tonnes·year-1). It is only since the late 1980s that subsistence catches have exceeded those from the 1950s, when there was a higher reliance on fisheries resources. Despite a small increase in subsistence catches, the human population has increased from approximately 3,550 to approximately 12,650, which resulted in per capita catch rates falling from 237 kg·person-1·year-1 (523 pounds·person-1·year-1) in 1950 to 78 kg·person-1·year-1 (171 pounds·person-1·year-1) in 2006. One of the main drivers for this was the decrease in the amount of fish used for dog feed, when the snowmobile replaced the dogsled as the main form of transportation. The more holistic historical perspective of total reconstructed fisheries catches presented here is important, in view of the impacts of global climate change, given the significance of these resources for the food security of arctic peoples. INTRODUCTION Alaskan marine fisheries in the arctic area are those that operate north of Cape Prince of Wales on the Seward Peninsula (Figure 1). This area falls within the United Nations Food and Agriculture Organization’s (FAO) Statistical Area 18. The National Marine Fisheries Service’s Alaska branch (NMFS- Alaska) does not report on these fisheries, because they take place within state waters. At the federal level, the National Marine Fisheries Service (NMFS-National) reports on Alaska’s fisheries, but they do not include catches taken in the arctic. As a consequence, the United States currently reports zero catches to FAO for the arctic area. The state agency, the Alaska Department of Fish and Game (ADF&G), has collected time series of commercial data and has also undertaken community subsistence studies that are intermittent in space and time. However, no complete time series of total marine catch estimates exist for the arctic coast of Alaska. Here, we present reconstructed estimates of total commercial and subsistence catches taken by the 15 coastal and near-coastal communities in Alaska’s arctic waters that form part of FAO Statistical Area 18 for the years 1950 to 2006. Fisheries in 1950 were under the mandate of the US federal government. However, driven in part by the desire of Alaskans to have control over their salmon resources, statehood was achieved in 1959. At this point, the State of Alaska took control of its own fisheries management. With the implementation of the Magnuson-Stevens Act in 1976, the federal government gained responsibility for fisheries taking place from 3-200 nautical miles from shore and the state retained responsibility for the fisheries occurring within 3 nm of the coast. After Alaska gained statehood, its subsistence use of fish and wildlife was given priority over all other uses. However, in subsequent years the Alaska Board of Fisheries and Game created 1 Cite as: Booth, S. and Zeller, D. (2008) Marine fisheries in arctic Alaska. Fisheries Centre Research Reports 16(9). Fisheries Centre, University of British Columbia [ISSN 1198-6727]. Marine fisheries catches in arctic Alaska, Booth & Zeller 3 a rural subsistence priority, which was later ruled to be in violation of the state’s constitution, and thus subsistence use and personal use fisheries are currently given priority. In 1999, the federal government also extended its jurisdiction to include fisheries on all public lands and waters under the Federal Subsistence Management Program (Woodby et al., 2005). The people of arctic communities have always relied on the Arctic Ocean for a large part of their sustenance. The area is sparsely populated, and the 15 communities represented in this study (Wales, Shishmaref, Deering, Buckland, Selawik, Kotzebue, Noatak, Kivalina, Point Hope, Point Lay, Wainwright, Barrow, Atqasuk, Nuiqsut, and Kaktovik) have an estimated total population of over 12,000 that grew at an average annual rate of 5.2 % per year from 1950 to 2000. The total population has since been slightly decreasing (Figure 2). Two communities, Atqasuk and Nuiqsut, were founded in the 1970s by people moving from existing communities to traditional lands. These 15 communities form part of three Alaska Native Regional Corporations—the ing Straits Native Corporation (Wales and Shishmaref), NANA Regional Corporation Buckland, Selawik, Kotzebue, Noatak, and Kivalina) and the Arctic Slope Regional Corporation (Point Hope, Point Lay, Wainwright, Barrow, Atqasuk, Nuiqsut, and Kaktovik). Marine commercial fisheries are important in Kotzebue Sound, with chum salmon (Oncorhynchus keta) the most important component of the catch, while marine subsistence fisheries are an important component throughout the area, and target a variety of species including chum salmon, whitefish (Coregonidae) and Dolly varden (Salvelinus malma).

For individual community information, see Appendix 3. relied on a mixed economy since the late 19th century, when American government and business expanded into the territory and developed commercial industries (Wolfe, 2004). Whaling, reindeer herding, and fur- trapping were important early contributors. After World War Two, the building of military stations (e.g., the DEW line) also provided the opportunity for people to earn wages. More recently, the discovery of oil on the North Slope in 1968 has enabled people to participate in a Marine fisheries catches in arctic Alaska, Booth & Zeller 4 mixed economy with the cash income helping some maintain a subsistence lifestyle. Since the mid-1960s, people have also largely replaced the dog sled with motorized transport (see also Booth and Watts, 2007, for the Canadian arctic). Furthermore, the development of oil fields has had effects on some animal populations, including Bowhead whales and caribou (National Research Council, 2003). MATERIALS AND METHODS ial catches were taken mainly from the 2004 and 2005 Annual Human population data mmerce, Community and Economic Development maintains the Alaska Time series estimates of commerc Management Reports (Kohler et al., 2005; Banducci et al., 2007), with additional unreported catches being estimated (see ‘Commercial fisheries data’ below). The Annual Management Reports detail the catch in numbers of individuals taken and average weights that were used to convert numbers of fish to round weight. A time series average for weight was used to estimate the weight of the catch in years when the report did not detail average weights. Arctic cisco taken in the Colville River fishery were assigned an average weight of 1 pound (0.45 kg; Daigneault and Reiser, 2007). Estimates of subsistence catches were taken from a variety of sources (see ‘Subsistence fisheries data’ below) and were expanded using a range of approaches to incorporate communities and years when no data were available. Subsistence catches in Alaska are often reported in terms of edible weight. If the edible weight to round weight conversion factors were not given, a standard conversion factor of 1.3 was used (i.e., round weight * 0.75 = edible weight; Anonymous, 2001) The Alaska Department of Co community database that provides population data for the first year of every decade (www.dced.state.ak.us), as well as estimates for 2005 and 2006. To estimate the population for each community and year, linear interpolations were performed between years of reported data. For Point Lay (the above data source did not report population for this community between 1940 and 1980), we used Point Lay Biographies (Impact Assessment Inc., 1989) to estimate the population between 1950 and 1980. Total population for the 15 arctic communities grew from approximately 3,550 in 1950 to 13,000 in 2000 at an average rate of 5.2 % per year, before declining to about 12,650 in 2006 (Figure 2). Commercial fisheries data heries for this area take place in the Arctic-Yukon-Kuskokwim region. The commercial fishery in Kotzebue Sound for chum salmon, along with incidental takes of Dolly varden However, although it is reported in official documents that the commercial fishery in Kotzebue Sound Administratively, commercial fis This region encompasses the drainages of the Kuskokwim, the Yukon and Colville Rivers, and includes both Norton Sound and Kotzebue Sound. However, the areas of the region that coincide with FAO Statistical Area 18 are Kotzebue Sound and the northern district of the Yukon-Northern area. Within these two areas, there are few commercial fishing opportunities, although a fishery that mainly targets chum salmon takes place in Kotzebue Sound, while another fishery in the Colville Delta targets whitefish. The commercial fishery for chum salmon in Kotzebue Sound is stated to have officially started in 1962 and the Colville River fishery officially commenced in 1967. Commercial catches were taken from the 2005 Annual Management Report and the 2007 Kotzebue Sound salmon season summary (Banducci et al., 2007; Menard and Kent, 2007). (Salvelinus malma), other species of salmon, and the fishery for sheefish (Stenodus leucichthys) is reported by the commercial fisheries department within ADF&G. Recent and historical data for these species were taken from the 2004 Annual Management Report (Kohler et al., 2005) and the 2005 Annual Management Report (Banducci et al., 2007). However, data for the commercial fishery that targets Arctic cisco largely in estuarine waters near the Colville River were taken from data supplied by Stephen Murphy (pers. comm.2). For the period 1974-1976 and 1981, unreported catches of Dolly varden were estimated using the respective average decadal catches. started in 1962, there were local commercial fisheries taking place prior to this. The commercial fishery taking place prior to that date was an informal one, whereby local people sold their catch for dog feed to people who ran dog-sled teams, the transportation link prior to the introduction of the snowmobile (C. 2 Stephen R.

Marine fisheries catches in arctic Alaska, Booth & Zeller 5 There was also a Japanese fishery in the Chuckchi Sea beginning in 1966, with most fishing effort taking Subsistence fisheries data eries as those targeting fish species that rely on marine waters as part of Subsistence fisheries catch data come from a variety of reports that are spatially and temporally Lean, pers. comm.3). Similarly, Stefanich (1973) reported that commercial fisheries taking place in the Colville River prior to 1967 were taking approximately 64,000 whitefish and ciscos each year; Wilimovsky (1956) estimated that 10,000 pounds of whitefish were taken in one instance in 1952. Thus, these two commercial fisheries had unreported catches estimated for the period prior to their official reporting by ADF&G. place between 66-67O N and 166-169O W, an area largely within the current boundaries of the US Exclusive Economic Zone. This fishery’s peak catches were similar to those for Kotzebue Sound, and thus, this fishery may have been intercepting large numbers of Kotzebue area chum salmon. Commercial data for the Japanese fishery are reported for 1966 and 1967 (Anonymous, 1967, 1968). Here, we define subsistence fish their life history. Thus, subsistence fisheries include both anadromous and marine fish species that are taken in marine, estuarine or freshwater environments, but exclude fish species that are solely reliant on freshwater for their life-cycle. Anadromous species including chum salmon, sheefish, whitefish and Dolly varden, and marine species, including herring (Clupea pallasii) and cod (Boreogadus saida and Eleginus gracilis), are the main species of importance. intermittent (Table 1) and form the basis for data ‘anchor’ points (see Zeller et al., 2007). Early studies such as those by Patterson (1974) quantify fisheries catches for several communities representing an average annual catch of important species. The State of Alaska, through its Community Profiles Database (www.subsistence.adfg.state.ak.us), maintains a database on subsistence fish catch and wildlife harvests that includes fisheries data for eleven of the fifteen communities, with most information derived from household surveys. Other studies mostly focus on a given community in a given year, although it is worthy to note that Burch (1985) presents data for Kivalina for two distinct time periods (1964-1965 and 1982- 1983). The data sources used to derive estimates of non-commercial, subsistence catches also indicated that the reported catch totals incorporated catches used for dog-feed. In order to account for catches that were not reported during these studies, yearly catches were estimated The two final methods involved scaling a community’s catch to either another community’s reported catch using several methods. The most common method involved interpolating between data anchor points via per capita catch rates. This method involves dividing reported catches of a year by the human population of the same year and then interpolating linearly between the per capita catch rates. Another method involved using average catches, whereby a community’s catch for reported years was divided by the number of years of reported data to derive an average catch, which was applied to other years when there were no data reported. This method was used in those cases where there was known to be large variations, including zero catches, due to ice in lagoon areas (Burch, 1985). The third method was to use the same reported catch for other years that lacked reported data; this was mostly done in carrying catches forward in time from the last reported catch amount, but was also used in some cases to carry catches backwards in time from the earliest reported catches. or to another species catch in the same community. Point Hope, Point Lay and Wainwright had only one reported anchor point for most species, and thus other anchor points in time were derived using reported changes for the same species in Kivalina. In Kotzebue, Dolly varden catches were estimated as a percentage of chum salmon catches, since there is some indication that higher catches of Dolly varden are associated with higher catches of chum. Chum salmon catches in Shishmaref were estimated by linearly interpolating the exploitation rate between two data anchor points (average 1971-1975 and 1989); for later years missing reported data the average exploitation rate was used. In Wales, chum catches were derived for 1971-1975 and 1989 using the reported change in catches for Shishmaref. For the intervening time periods, catches were estimated by linear interpolation of the exploitation rate. Eggers and Clark (2006) provide estimated total run sizes for Kotzebue District chum for 1962-2004. Catch data were converted into exploitation rates by dividing the number of chum salmon caught in reported years by the estimated 3 Charlie Lean, Norton Sound Fisheries Research and Development Director, P.O.

Average reported weights from the commercial fishery for chum in Kotzebue Sound were used to convert the number of salmon to live weights. Detailed data and all sources used are presented in Appendix 1. Human vs. dog feed component of subsistence catches Prior to the introduction of the snowmobile in the early 1960s, dog-teams provided the main mode of transportation. The first snowmobiles were sold in Kotzebue in the early 1960s and by the winter of 1965- 66 the first snowmobiles were brought into Noatak (Hall, 1971). Therefore, we assumed that for communities other than Kotzebue, the snowmobile was introduced in 1965 and for Kotzebue in 1963. Fish were one of the main sources of feed for the dog-teams in some communities. Abrahamson (1968) reported that a dog would need at least 2 pounds of dried fish per day over the winter. C. Lean (pers. comm.) indicated that in the past a dog would be fed half a chum salmon (approximately 4 lbs, given an average weight of 8 lbs per chum) during the winter, and during the rest of the year, they would be fed with other protein sources (e.g., caribou). Thus, we considered that, prior to the introduction of the snowmobile, each dog would be fed 4 pounds of fish each day over a 6 month period prior to the introduction of the snowmobile. Raleigh (1957, in Mattson 1962), gave estimates for the number of dogs in the 1950s in each community excluding Wainwright, Barrow, Kaktovik, Selawik and Point Lay. Estimates of the number of dogs for communities lacking data were based on the average dogs-to-people ratio for those communities that had reported data. Patterson (1974) also provided an estimate for the total number of dogs in 1972 for the NANA region, which includes communities outside the scope of this work. However, Raleigh (1957 in Mattson 1962) also provided estimates for these communities and thus, the number of dogs in 1972 for each of the communities was based on the percentage decline of total dogs between 1957 and 1972. For 1957, we assumed that each dog was fed 4 pounds of fish per day over a 6 month period. For 1972, Patterson (1974) estimated that each dog was fed 327 pounds (round weight) of fish per year. Georgette and Loon (1993) estimated the amount of fish fed to dogs for the community of Kotzebue in 1986 and estimates are also provided for Noatak in 1999 (Georgette and Utermohle, 2000) and 2000 (Georgette et al. 2001). These data were transformed into anchor points based on the amount of fish used for dog-feed (as a percentage) in relation to the total estimated fish catch. The 1957 estimate of the amount of fish used for dog-feed (as a percentage of the total estimated fish catch) was held constant until the year the snowmobile was introduced (Kotzebue 1963, all others 1965) and then scaled linearly to the 1972 estimate. For the communities that did not have any data available past the 1972 estimate, we scaled the amount of fish used for dog feed on the percentage change for Noatak because Kotzebue, as a regional centre, has a much larger population. Thus, it was possible to estimate, for each community, what percentage of catch through time was fed to dogs by linearly interpolating between anchor points. However, for some communities the estimates of fish used for dog-feed exceeded the reported catch for the anchor years of 1957 and 1972. On further investigation, it was found that these communities relied far less on fish as a protein source and relied more heavily upon land or marine mammals. Estimates of total protein availability for each community were based on the report of Patterson (1974), who provided estimates on the weight of caribou, deer/reindeer, moose, seals, walrus, beluga, bowhead whales and birds taken in each community. The estimated amount of fish caught was added to these amounts and a percentage contribution to the available protein by fish was determined. The communities of Wales, Shishmaref, Point Hope and Kaktovik were found to have a negative balance, and they also had fish contributing less than 15 % to their protein availability, and therefore we assumed that they did not rely heavily on fish for dog-feed. Therefore, we were also able to determine that the communities of Wainwright and Barrow, which were missing information on the number of dogs, were not heavily dependent on fish as dog-feed because they had fish contributing 3 % and 5 %, respectively to their total protein availability. No data were available for Point Lay, quantifying the number of dogs or contributions to protein availability, although the community is known for its beluga harvest (B. White, pers. comm.4); therefore it was assumed that fish were not relied upon for dog-feed for the following communities: Barrow, Kaktovik, Point Hope, Point Lay, Shishmaref, Wainwright, and Wales. Thus, for each community that was reliant upon fish for dog-feed (Deering, Buckland, Kotzebue, Noatak, 4 Bruce Wright, Senior scientist, Aleutian Pribilof Islands Association, 1131 East International Airport Rd., Anchorage Alaska 99518, (907)-276-2700 [date information received: January 24, 2008]. Marine fisheries in arctic Alaska, Booth & Zeller 9 Kivalina and Selawik) we were able to determine through time what percent of the estimated catch was used for dog-feed. For the communities of Atqasuk and Nuiqsut, that were established on traditional lands in the 1970s, the average percentage (excluding Kotzebue) was used to determine what proportion of fish was used for dog-feed in the first year that people re-settled traditional lands and the decline was based on changes represented by the community of Noatak. Although Deering in 1957 had a positive protein availability balance, the protein availability balance was negative in 1972, and therefore the change in the amount of fish fed to dogs was based on the average percent decline for the other communities, excluding Kotzebue. RESULTS Total catch time series Prior to 1962, when commercial fisheries were part of the informal economy, total estimated catches averaged approximately 1,230 t·year-1 (2.7 million lbs·year-1; 1950-1961), with the informal commercial sector accounting for on average 31 % of the yearly catch (Figure 3). For the first years when the commercial fishery was considered to be part of the formal economy (1962-1969), total catches were estimated to average approximately 1,080 t·year-1 (2.4 million lbs·year-1). From 1970-1989, there were two peak periods of catches, 1974-1975 with catches of 3,178 and 2,909 tonnes (7.0 and 6.4 million lbs) respectively, and then in 1981-1982 with catches of 3,529 and 2,609 tonnes (7.8 and 5.8 million lbs), respectively. Catches for 1970-1989 averaged approximately 1,981 t·year-1 (4.4 million lbs·year-1). During the 1990s, catches averaged approximately 1,651 t·year-1 (3.6 million lbs·year-1) and in the early 2000s estimated total catches had declined to 1,355 t·year-1 (3.0 million lbs·year-1; Figure 3). Total commercial and subsistence catches over the time period considered here amount to approximately 89,000 tonnes (196 million lbs). The most important species is chum salmon, which accounts on average for 55 % of the total yearly catch. The whitefish complex (whitefish + ciscos) is the next most important taxon, accounting for on average 21%, while sheefish and Dolly varden account for 12 % and 8 % of the total yearly catch, respectively (Figure 4). Subsistence catches Subsistence catches account for approximately 54 % of the estimated total catches (Figure 3a). From 1950- 1965, prior to the Japanese high seas fleet fishing in the Chuckchi Sea, subsistence catches averaged 850 t·year-1 (1.9 million lbs·year-1), but declined to around 685 t·year-1 (1.5 million lbs·year- 1) from 1966-1979. Catches increased to average 791 t·year-1 (1.7 million lbs·year- 1) during the 1980s and it was only since the late 1980s that subsistence catches have consistently surpassed catches from the 1950-1966 time period. Since 1990, subsistence catches have averaged 1,000 t·year-1. Despite increases in subsistence catches, subsistence per capita catch rates have declined from 237.0 kg·person-1 (522.6 lbs·person-1) in 1950 to 77.8 kg·person-1 (171.5 lbs·person-1) in 2006. The sharpest drop in subsistence per capita catch rates came from 1950-1971, with an estimated decline of approximately 60 %. Between the 1950s and 1990s, there has been a 2.4-fold drop in subsistence per capita catch rates (Figure 5). 0 500 1,000 1,500 2,000 2,500 3,000 3,500 4,000 1950 1960 1970 1980 1990 2000 Year C at ch (t ) Commercial Subsistence 0 200 400 600 800 1,000 1,200 1950 1960 1970 1980 1990 2000 Year C at ch (t ) Human component Dog component a) b) C at ch (t ) C at ch (t ) C at ch (t ) C at ch (t ) C at ch (t ) C at ch (t ) Figure 3. a) Estimated total marine and anadromous fisheries catches (excluding marine mammals) by fishing sector for 15 coastal and near-coastal communities of Arctic Alaska, and b) breakdown of subsistence catch into estimated amounts destined for human consumption and for dog-feed. Marine fisheries in arctic Alaska, Booth & Zeller 10 Use of fish for dog-feed For the eight communities that we determined were reliant on fish for dog-feed, the percentage of fish for dog-feed accounted for 58 % of the catch total in 1950 declining to 6 % in 2006. Prior to the introduction of the snowmobile (1950-1962), it was estimated that the amount of fish fed to dogs averaged 459 t·year-1 (1 million lbs·year-1). From 1963 to 1975, the amount of fish required for feed dropped from an estimated 387 t·year-1 (843,000 lbs·year-1) to 82 t·year-1 (181,000 lbs·year-1) or from 56 to 14 % of the estimated total subsistence catches for the eight communities. Since 1976, catches for dog-feed have averaged 65 t·year-1 (143,000 lbs·year-1) and have declined from 13 % to 6 % of total catches (Figure 4). Commercial catches Commercial fisheries that were part of the informal economy from 1950-1961 were estimated at 382 t·year-1 (842,000 lbs·year-1). Commercial fisheries catches in 1962 were estimated at 553 tonnes (1.2 million lbs), but did not reach that level again until 1970. From 1963-1969 commercial catches averaged 249 t·year-1 (548,000 lbs·year-1); during the 1970s reported catches averaged 1,097 t·year-1 (2.4 million lbs·year-1), rising to around 1,408 t·year-1 (3.1 million lbs·year-1) in the 1980s, before declining in the 1990s to average 621 t·year-1 (1.4 million lbs·year-1). In 2000-2001, catches averaged 732 t·year-1 (1.6 million lbs·year-1), but due to market conditions recent commercial catches have been low, averaging 226 t·year-1 (497,000 lbs·year-1) from 2002-2006. Chum salmon are the main contributors to the commercial catch totals accounting for an average of 93 % of total commercial catches. Peak years for chum occur every 3 to 4 years (Figure 4). DISCUSSION The data presented here are estimates of fisheries catches for species that spend at least a portion of their life-cycle in marine waters (excluding marine mammals) taken from 1950-2006 by 15 coastal and near- coastal communities in arctic Alaska. The data estimated here more likely represent total catches than those presented by reporting agencies, and may serve as baseline data for this area, which is also lacking adequate baseline data for marine mammals (Hovelsrud et al., 2008). Furthermore, it may also be wise to heed the call for a ban on commercial fishing in this area to prevent fishing fleets from expanding into this area 0 500 1,000 1,500 2,000 2,500 3,000 1950 1960 1970 1980 1990 2000 Year C at ch (t ) Chum salmon 0 200 400 600 800 1,000 1950 1960 1970 1980 1990 2000 Year C at ch (t ) Whitefish Sheefish Dolly varden Other salmon Cod Herring Others a) b) C at ch (t ) C at ch (t ) C at ch (t ) C at ch (t ) C at ch (t ) C at ch (t ) Figure 4.

Estimated subsistence per capita catch rates (total catches/total human population) for arctic Alaska, 1950-2006 for 15 communities. Marine fisheries in arctic Alaska, Booth & Zeller 11 as the ice recedes (Biello, 2008). This would also allow the local people to maintain food security in the face of climate change and a changing ecosystem; the loss of resources that the people have always relied on would have dramatic effects on the culture of the people. Although the state agency, the ADF&G, reports on both fishery sectors, these data do not make it to either the national (NMFS) or international (FAO) organizations. A catch-reporting system more transparent to the public, including data transfer information between the state, regional, national, and international agencies is needed so stakeholders can more easily access and understand data and their limitations for policy and decision-making processes. Having a baseline of information available on total fisheries catches is also important in light of global warming, and impacts from ongoing developments. Commercial catches have been in decline since peaking in the early 1980s. However, the drop since 2000 is due to a limited market situation (one buyer only), and subsistence catches have increased during this time. However, the increase in subsistence catches is small compared to the growth in human population, thus resulting in a declining per capita subsistence catch rate and hence per capita supply. There has been a 3.3 fold decline in subsistence per capita rates from the 1950s to 2006. This value is much lower than that for the Canadian arctic, where subsistence per capita rates in coastal communities in the Inuvialuit region dropped approximately 15 fold between 1950 and 2001 (Booth and Watts, 2007). The difference is due to the higher reliance on fish for dog-feed in the Mackenzie Delta area, where it was reported that catches of marine and anadromous fishes were approximately 4 times higher in 1960 compared to the data source study years, 1988-1997 (Usher, 2002). Although it appears that the commercial fisheries are well-monitored, a more regular, systematic survey method would lead to a better understanding of subsistence fisheries. It is interesting that the commercial fishery sector appears to report all catches. However, it is the subsistence use, which is given priority in the state constitution, which seems to be lacking consistent, detailed and comprehensive data. A subsistence survey design incorporating each community in a specified time interval, with abundance indices for species in non-survey years would assist in clarifying actual subsistence catches. Specific attention to all salmon species would also benefit the efforts to track global warming effects, since species’ distributions will be affected. Coho salmon in Norton Sound have been increasing in abundance over the last two decades, but tracking similar changes in areas further north is currently difficult since salmon species, besides chum, are often described as ‘other’ salmon in reports. However, it should be noted that chinook salmon do appear to have extended their historical distributions northwards because they have been appearing in Barrow since the mid-1990s and there is no local Inupiaq name for them (C. George, pers. comm.5). Previously, the furthest reported extent of this species was Wainwright. The data anchor points used here are from a variety of sources. These sources may not have scaled up catches to a community level, and thus our estimates may be missing data. This is because early reported catches may be observed amounts, whereas later reports are based mainly on a household survey method, which includes estimates for non-reporting households. However, these anchor points do allow an assessment of more likely catches for the years when no data have been collected at all. The estimates of catches presented here are likely conservative, since no marine catches have been estimated for inland communities that may still have summer camps for fishing near marine waters or that fish for anadromous species further inland.

Marine fisheries in arctic Alaska, Booth & Zeller 14 APPENDIX 1: METHODS OF EXPANSION AND ANCHOR POINTS Anchor points of reported catch were determined from the indicated references and are identified as ‘Source’. Anchor points are all presented in pounds (lbs), and a conversion factor of 0.4536 was used to convert pounds to kilograms. Methods of expansion include the manner in which interpolations were done between anchor points, and are as follows: Derived anchor from another community: this method used information from another community to scale catches for the present community. For example, Atqasuk had catches of Broad whitefish scaled to the catch changes noted in Barrow from 1983 to 1977 to derive a catch anchor for the first year of catches in Atqasuk. Avg taxa % * total catch: this method involved using the interpolated catch value for a community and in order to derive taxonomic entities, the reported taxa amount for anchor years was summed and an average taxonomic percentage was calculated. This taxonomic percentage was applied to all years that had interpolated catch data to derive catch by species. (Year) catch: this method used the stated catch for other years when there were no anchor points. Pop * per cap scaled: this method accounts for scaling a per capita rate between two anchor points. Catch data were first transformed into per capita rates (catch/human population) and then linearly interpolated between anchor years. The per capita rate was then multiplied by the population to estimate catches. Avg catch: the reported catch over the number of years indicated that had reported data. Pop * avg per cap: reported catch data were transformed into per capita rates and an average per capita rate was calculated to use in conjunction with the population data to estimate catches. Proportion of a species: this method was used in some cases where the taxonomic entities were not well defined or reported through time inconsistently; largely a problem with the whitefish/cisco complex. In these cases, the taxonomic entities were pooled across years, and one taxon’s catch was based as a proportion of another. For example, reported data for Kaktovik included whitefish in 1971; cisco in 1985 & 1986; Bering, least and, Arctic cisco in 1992; and only Arctic cisco was reported in 2001 & 2002. Knowing that historically the main fishery is for Arctic cisco and that some least cisco are caught incidentally , the catch of least cisco was estimated as a proportion of the catch of Arctic cisco based on the year 1992, when there is full taxonomic accounting. Raised anchor’s avg catch: this involved raising the calculated average catch of one species to account for the average weight of a single fish and was used for sockeye salmon in Noatak. The average catch for the reported years (2.6 lbs) was less than a single individual (5 lbs) and thus this value was raised to account for the average weight of a single sockeye salmon in non-anchor years. Scaled to changes presented in (source): reported catch totals (anchor points) were scaled to catch data presented in the source document, which presented a time series of subsistence data. Scaled as proportion of another community’s catches: One community’s catches were scaled as a proportion of another community’s catches for the same taxon; used to scale Selawik’s catches of chum salmon and Dolly varden to Kotzebue. Scaled via exploitation rate: total run size (by number) of chum salmon was estimated for Kotzebue area chum salmon by Eggers and Clark (2006). Thus, it was possible to calculate an exploitation rate (number salmon taken/total run size) for anchor years. For periods of no data, catches were estimated by linearly interpolating between exploitation rates and multiplying by the total run size. Table A1.1.

Estimated population grew from 74 in 1977 to 237 in 2006 (Figure 3.1). Atqasuk had the catches of all taxa summed over all years to derive a taxonomic breakdown for catches. For non-anchor years, the catches were apportioned to taxa based on the average reported proportion for the two anchor years (1983 & 1994). Atqasuk had its 1977 catch total scaled from the 1983 anchor point by using the change in Barrow’s catch over the same time period. Barrow was used to scale the catches because this community was established by former residents of Barrow. 0 50 100 150 200 250 1977 1982 1987 1992 1997 2002 Year Figure A3.1.

Marine fisheries of arctic Alaska, Booth & Zeller 45 Barrow Barrow is the northernmost community in North America and residents still participate in traditional marine mammal hunts. The development of oil fields at Prudhoe Bay has established it as the economic center of the North Slope Borough, and tax revenues from the North Slope oil fields fund services throughout the borough (www.dced.state.ak.us). The population is estimated to have grown from 951 people in 1950 to 4,065 people in 2006. Patterson (1974) identified (6,250 lbs) of “herring” being taken. However, C. George (pers. comm.1) noted that Pacific herring were not caught in subsistence nets, but rather these should be identified as cisco. He also noted that it was only recently (1990s) that king salmon (Oncorhynchus tshawytscha) appeared in local waters and that there was no local Inupiaq name for them, and coho salmon (O. keta) were also likely to have been misidentified, as a result of chum salmon being called ‘silver’ salmon- the common name in Alaska for coho salmon. Also, Arctic charr were split between Dolly varden (anadromous) and Arctic charr (freshwater) based on information provided by Craig George. He noted that about 10% of what was formerly identified as Arctic char was taken in lakes near Barrow and that the other 90% were taken in marine waters and therefore would be Dolly varden. 0 1,000 2,000 3,000 4,000 5,000 1950 1960 1970 1980 1990 2000 Year Po pu la tio n Figure A3.3. Estimated population of Barrow 1950-2006; solid circles indicate census years. Thus, what was originally identified as herring (Patterson, 1974) was changed to cisco in the present study, and records of coho salmon and king salmon were changed to chum salmon (Patterson, 1974; Anonymous, 2001). It should also be noted that Craig (1987) in a survey of salmon streams in this area only identified appearances of coho and king salmon as strays, usually with only one specimen being caught. Chum salmon catch data for the years 1987 and 1988 (1,587 and 853 pounds) as indicated in the CPDB were ignored. This was because the values were low in relation to the other anchor points and because the Community Profiles Database indicated that these years were not the most representative for the community.

Box 69, Barrow, Alaska 99723, (907)-852-2611 [date information received January 24, 2008]. Marine fisheries of arctic Alaska, Booth & Zeller 46 Buckland Buckland is located on the Buckland River, and a herd of more than 2,000 reindeer are managed, with the workers being paid in meat (www.dced.state.ak.us). In 1972, Buckland experienced a food shortage (Moore, 1979) and was given special permits for increasing the subsistence food supply in that year. The population is estimated to have grown from 102 people in 1950 to 457 in 2006. Buckland’s reported catch of chum salmon declined dramatically after 1960. Part of this decline may have been due to the introduction of the snowmobile. However, the decrease demand for protein sources due to the introduction of the snowmobile does eem to match with the noted food shortage in 1972. It is possible that the Japanese high-seas fishing fleet may have catching chum salmon destined for the Buckland River, resulting in the depressed catches after 1968. However, it should also be noted that hatcheries were in response to record low returns of wild stocks in the 1960s and 1970s and therefore it is possible that the low ction levels may signal other factors low returns during this period noaa.gov/japan/aquaculture not s been developed produ in the (www.lib. 2). 2 Heard, W.R.

Moose, seal and beluga provide most meat sources (www.dced.state.ak.us Deering is ). The population was estimated at 174 in 1950 and has declined to 138 in 2006. Charlie Lean3 stated that 1984, 1994 and 2004 were record pink salmon runs; therefore, the 1994 per capita rate was applied to these years. Deering’s reported catch of chum salmon declined dramatically after 1960, and coincides with Buckland’s decline. Part of this decline would have been attributed to the introduction of the snowmobile. However, the decrease demand for protein sources due to the introduction of the snowmobile does not seem to match with the noted food shortage in 1972. It is possible that the Japanese high-seas fishing fleet may have been catching chum salmon destined for the rivers in the area, resulting in the depressed catches after 1968. However, it should also be noted that hatcheries were developed in response to record low returns of wild stocks in the 1960s and 1970s and therefore it is possible that the low production levels may signal other factors in the low returns during this period (www.lib.noaa.gov/japan/aquaculture). 3 Charlie Lean, Norton Sound Fisheries Research and Development Director, P.O.

Currently, the people carry out some subsistence activities within the Mackenzie Delta, which overlaps with the harvests by people of Aklavik, Canada (Pedersen et al., 1985). In 1985, the main subsistence resource harvests, in order of importance, were Bowhead whale, fish, and caribou. In 1985 all households participated in fishing activities (Pedersen et al., 1985).

Pedersen (2005) did not list Bering cisco as being harvested by Kaktovik residents and therefore the catch for Bering cisco was changed to Arctic cisco. The subsistence fishery targets Arctic cisco migrating out of the Mackenzie River and the catches are influenced by wind direction, westerly winds are associated with higher catches. 0 2 4 6 8 10 1950 1960 1970 1980 1990 2000 Year C at ch (t ) Dolly varden Arctic cisco12 14 Others 0 2 4 6 8 10 1950 1960 1970 1980 1990 2000 Year C at ch (t ) a) 12 14 b) C at ch (t ) C at ch (t ) C at ch (t ) C at ch (t ) C at ch (t ) Figure A3.10. a) Anchor points (solid circles), and estimated reconstructed total catches (line), and b) taxonomic breakdown of the reconstructed catches with ‘others’ consisting of Arctic cod, flounder, least cisco, salmon (unidentified), pink salmon, and saffron cod.

The near-by Wulik River is also important for subsistence use. Kivalina has grown from an estimated population of 117 people in 1950 to 391 people in 2006. The Wulik River supports small populations of chum, pink, and sockeye salmon. Pink salmon spawn in the lower 6 miles of the Wulik River, chum salmon spawn in the lower 15 miles of the river, while sockeye salmon spawn below Wulik Forks (www.nwabor.org/planning/4.05%20Coastal% 20Mgt/Chapter%206%20Description%20of% 20Designated%20Areas.htm4). The early report by Saario and Kessel (1966) resents data by harvest year (Aug-July) and c depending on the year neither species was caught, only o p therefore these harvest years were used as surrogates for calendar years. Therefore, for instance, the first harvest from Aug 1959 to July 1960 was treated as the calendar year 1959. Arctic cod and Saffron cod had their hes for years of no data. This was done because ne species was caught, but in some years both species were caught. This allowed the catch to be split (by using the average proportion for each species for anchor years) between both species for years when an interpolation was done. catch totals combined in order to interpolate total cod cat 4 Anonymous (2005) Northwest Arctic Borough coastal management plan-public review draft.

There are three near-by rivers, the Kobuk, Noatak and Ssezawick Rivers. As well, Hotham Inlet, which is the outlet for the Kobuk and Selawik Rivers, is located on the east side of the peninsula and this inlet is linked to Selawik Lake (www.dced.state.ak.us ). The estimated population has grown from 623 people in 1950 to 3,104 in 2006.

The earliest studies used for this report arose from environmental studies for Project Chariot, which in the 1950s aimed to create a harbor near Point Hope by detonating nuclear material.

The workshop was held on January 24, 2008 immediately following the 2008 Alaska Marine Science Symposium. Local logistic and organizational support was organized by Jonathan Warrenchuk and Susan Murray of Oceana-Juneau, Alaska. Thirteen people participated in the one day workshop (Table A4.1), with opening comments by Daniel Pauly concerning the state of global fishery statistics, and Dirk Zeller expanding on the purposes and examples of why catch reconstructions are needed. Thereafter, Shawn Booth communicated the preliminary results for the individual catch reconstructions for ten marine coastal communities. After presenting the preliminary data for each community, participants were invited to give feedback on the reconstruction, which was largely related to the subsistence fisheries sector. Two general concerns arose: standardizing common names of fish species used in historical documents to the correct scientific names; and increasing the number of communities to include some which that, although not physically located on the coast, nevertheless are considered significant users of marine species, including anadromous salmon species. Common names were standardized between communities and assigned both the scientific names and Inupiat names for the species; the catch reconstruction was expanded to include the communities of Selawik, Nuiqsut, Atqasuk, Noatak, and Buckland. However, although workshop participants suggested including catches of Little Diomede Island, the catches were not reconstructed because the island is located south of the boundary for FAO Statistical Area 18. Furthermore, the community is largely dependent on walrus and other marine mammals, and it is only recently that the people have begun to string nets around the islands (J. Menard, pers. comm.8). The five other communities that were included for the expanded reconstruction were located inland, but they do rely on anadromous species of fish (i.e., salmon and whitefish complex), which spend at least a portion of their life-cycle in marine waters.
