Determining the effects of sediment deposition on the growth, survival, and foraging efficiency of the endangered Nooksack dace (Rhinichthys cataractae sp. cataractae), and on the abundance, distribution, and community structure of their invertebrate prey. Champion, John Michael

Abstract

Alterations to riverine habitats from the excessive deposition of sediments present a challenge for the effective management and conservation of aquatic resources and endangered species. The Nooksack dace (Rhinichthys cataractae sp. cataractae) is an endangered, benthic riffle-dwelling specialist, which is threatened by sediment-induced habitat changes. The purpose of my thesis was twofold. First, using semi-natural streamside channels I experimentally tested how different levels of embeddedness and percentages of fine sediments
