Book excerpt: I conducted a study to identify potential spawning habitat for anadromous salmonids above a 60-year-old hydropower dam in the headwaters of the North Umpqua River in Oregon. Like many other historical salmonid-bearing rivers, little documentation exists for anadromous fish presence above potential natural obstacles upstream of Soda Springs Dam. My prediction was that if migratory salmonids are allowed to move upstream of the dam using a new fish ladder they would utilize available upstream spawning habitat. I captured, radio-tagged, and transplanted wild adult summer steelhead, O. mykiss, above Soda Springs Dam and tracked daily movements for 1 year to observe habitat preferences. I also investigated evidence of historical anadromy throughout the North Umpqua River basin using stable isotope analysis of salmon-derived nitrogen (15N) in foliar samples from Douglas fir trees, P. menziesii, (>100 years old). I tested the hypothesis that I could identify undocumented, historical salmon spawning reaches above natural and anthropogenic obstacles based solely upon [delta]15N foliar deposition patterns. While tracking radio-tagged steelhead, I documented holding locations, the timing of spawning activities, and the outmigration of kelts. Tagged fish did not show any extensive movement in the river or tributaries above the dam. Most of the tagged adults showed incremental daily movements near the release site or downstream into the hydropower reservoir but did not travel further than 1 kilometer upstream in the main river channel. I recorded movements and localized activities that suggested some of the fish spawned and subsequently moved downstream towards the Pacific Ocean. My observations indicated that spawning behavior of tagged fish above Soda Springs Dam was delayed several weeks relative to fish spawning below the dam. There was no evidence from telemetry that any fish moved upstream in Fish Creek, the newly accessible habitat of interest in this project. My data suggest that steelhead will use restored habitat above dams, but that re-colonization activities are variable and may be affected by altered flow regimes within the restored habitat upstream of the dam and intra-specific density dependence. My stable isotope data indicated that the foliar [delta]15N deposition patterns were confounded with elevation. I documented potential "salmon-derived" false positives on the Umpqua National Forest above impassable waterfalls. Overall I found that foliar [delta]15N deposition patterns were highly variable and unexpectedly indicated a statistically significant negative correlation of foliar [delta]15N values with historical salmon presence. My linear mixed-effects modeling suggests that the presence of salmon is the most important indicator of foliar [delta]15N values, rather than the proximity of a sampled tree to stream flow above or below migratory barriers. I was not able to use the mixed effects model to identify previously undocumented salmon spawning habitat. My results from the foliar technique suggest that the method may not be universally applicable as has been previously suggested in the literature.

Available in PDF, EPUB and Kindle. Book excerpt: Rainbow smelt (Osmerus mordax) have invaded many North American inland lakes, and their distribution continues to expand. Their broad dietary and habitat tolerances permit smelt to interact with numerous trophic levels, including zooplankton, planktivores, benthivores, and piscivores. Major concerns include the potential for rainbow smelt to extirpate native planktivores through a combination of competition and predation, their potential to weaken sport and commercial fisheries through competition and predation on juvenile game fish, and their potential to produce a trophic cascade that accelerates eutrophication. Enhancing adult piscivore populations has proven effective at reducing smelt populations; however, preventing smelt invasion is the preferred management strategy. Accidental and deliberate introduction by humans has been the primary mode of smelt range expansion, thus programs should be aimed at increasing public awareness of the risks of smelt invasion. Future research should examine multiple scales and should include both pelagic and benthic components because smelt have the potential to impact ecosystems at all levels. Recently developed models that forecast smelt distribution should be combined with current distributional data to help managers prioritize lakes at a greater risk of invasion. Investigation into the interaction between smelt invasion, climate change, and expanding human settlements is also necessary.

Available in PDF, EPUB and Kindle. Book excerpt: International Conference on Fish Migration and Bypass Channels held in Vienna in September 1996. It covers the range of fish pass technologies currently in use throughout the world and attempts to develop a wider, more ecological perspective on this formerly engineering-orientated discipline. Emphasis is placed on enhancing an understanding of fish migration behaviour, and achieving optimum design to meet the behavioural requirements of all known migratory species. Additional attention is paid to comparing the European trend towards constructing nature-like bypass channels with the highly technical solutions dominant in North America.

Available in PDF, EPUB and Kindle. Book excerpt: Global warming and climate change are growing environmental concerns which are much in the scientific, governmental and public eye. The potential impact on freshwater and marine fishes is immense, because most fish have no physiological ability to regulate their body temperature. This volume focuses on the effects of temperature at all levels of organization in fish, with particular emphasis on physiological function: cells, epithelia, organ systems, the whole organism, reproduction, behaviour, pollutant interactions, ecology and population dynamics, with each chapter written by experts in the field. Many chapters also speculate on the long-term physiological and ecological implications to fish of a 2-4°C global warming scenario. Researchers and graduate students in the areas of animal physiology and behaviour, environmental toxicology, population ecology and fisheries biology and management will find this volume of particular interest.

Available in PDF, EPUB and Kindle. Book excerpt: The need for ion and water homeostasis is common to all life. For fish, ion and water homeostasis is an especially important challenge because they live in direct contact with water and because of the large variation in the salt content of natural waters (varying by over 5 orders of magnitude). Most fish are stenohaline and are unable to move between freshwater and seawater. Remarkably, some fishes are capable of life in both freshwater and seawater. These euryhaline fishes constitute an estimated 3 to 5% of all fish species. Euryhaline fishes represent some of the most iconic and interesting of all fish species, from salmon and sturgeon that make epic migrations to intertidal mudskippers that contend with daily salinity changes. With the advent of global climate change and increasing sea levels, understanding the environmental physiology of euryhaline species is critical for environmental management and any mitigative measures. This volume will provide the first integrative review of euryhalinity in fish. There is no other book that focuses on fish that have the capacity to move between freshwater and seawater. The different challenges of salt and water balance in different habitats have led to different physiological controls and regulation, which heretofore has not been reviewed in a single volume. - Collects and synthesizes the literature covering the state of knowledge of the physiology of euryhaline fish - Provides the foundational information needed for researchers from a variety of fields, including fish physiology, conservation and evolutionary biology, genomics, ecology, ecotoxicology, and comparative physiology - All authors are the leading researchers and emerging leaders in their fields
