The relation of the ecological conditions in Bear Lake, Cassiar District, British Columbia, to the production of Sockeye salmon Foskett, Dudley Robert


Tie conditions in a geologically youthful area are outlined, and also the chemical and biological conditions in Bear Lake of the Skeena watershed. The life history of the sockeye, Qncorhynchus nerka, in this area is outlined as closely as information permits. The spawning of the sockeye where stream conditions are generally unfavourable and the probability of lake spawning in the deeper waters is discussed. The contribution of this area in relation to the whole Skeen sockeye run is estimated.
