This book was released on 2011 with total page 132 pages. Available in PDF, EPUB and Kindle. Book excerpt: A number of steelhead (Oncorhynchus mykiss) populations are at risk throughout Oregon, including five populations that are federally listed as threatened or endangered. However, little is known about behavior and survival of these fish as they transition from freshwater to seawater. We investigated whether estuarine survival varies on a temporal scale within or between years, on a spatial scale between zones within the estuary, and between basins within the same distinct population segment. We implanted acoustic transmitters on 69 wild steelhead smolts in the Nehalem basin and 70 in the Alsea basin and compared run timing, migration rate, and estuarine residence times between basins. We also measured gill ATP-ase levels and parasite loads in each basin to evaluate the relationship between these indices and migration timing, life history strategy or age of smoltification. In general, only 40-50% of the wild steelhead smolts tagged at upstream smolt traps were detected entering the ocean, although survival was highly variable among years. The majority of "mortality" occurred in the lower estuary near the mouth. Wild steelhead smolts spent a median of 0.72 and 0.83 d in the estuary in the Nehalem and Alsea basin, respectively, in 2009. This research provides a baseline by which we can monitor temporal changes in the survival and behavior of juvenile salmon in the estuary. Such information is vital for monitoring the impact of estuarine restoration and reiterates the importance of the lower river and estuary environment for smolt survival.

Book Synopsis Trout and Salmon of North America by : Robert Behnke
Download or read book Trout and Salmon of North America written by Robert Behnke and published by Simon and Schuster. This book was released on 2010-07-06 with total page 376 pages. Available in PDF, EPUB and Kindle. Book excerpt: This beautiful and definitive guide brings together the world's lead leading expert on North American trout and salmon, Robert Behnke, and the foremost illustrator in the field, Joseph Tomelleri. North America is graced with the greatest diversity of trout and salmon on earth. From tiny brook trout in mountain streams of the Northeast, to cutthroat trout in the rivers of the Rockies, to Chinook salmon of the Pacific, the continent is home to more than 70 types of trout and salmon. How this came to be, how they are related, and what makes them unique -- and so breathtaking -- is the story of Trout and Salmon of North America. The more than 100 illustrations of trout and salmon by Joseph Tomelleri showcased here exhibit a genius for detail, coloration, and proportion. Each portrait is made from field notes, streamside observations, photographs, and specimens collected by the artist. The result is a set of the most accurate and stunning illustrations of fish ever created. Robert Behnke has distilled 50 years of his research and writing about trout and salmon in completing this book. No one understands better than Behnke the diversity and conservation issues concerning these fishes or communicates so lucidly the biological wonders and complexities of their particular beauty. Also included are more than 40 richly detailed maps that clearly show the ranges of populations of trout and salmon throughout North America. An irresistible delight for anyone who appreciates natural history, Trout and Salmon of North America is a master guide to the natural elegance of our native fishes.

Book Synopsis Physiological and Energetic Constraints on Iteroparity in Steelhead Trout (Oncorhynchus Mykiss) by : Zachary L. Penney

This book was released on 2013 with total page 356 pages. Available in PDF, EPUB and Kindle. Book excerpt: Steelhead trout (Oncorhynchus mykiss ) are anadromous and iteroparous, but repeat-spawning rates are variable. In this dissertation, the physiological and energetic constraints of iteroparity were evaluated in inland Snake/Columbia River stream-maturing steelhead at selected phases of the reproductive cycle. In chapter 1, histological analysis was used to assess the effects of prolonged fasting on the cellular architecture of tissues in sexually mature and kelt steelhead. We found little evidence of severe cellular necroses in the tissues and observed that many kelts were feeding during emigration. In chapter 2, we examined changes in the lipid, protein and energy density of white muscle samples. At a broad scale, we determined that white muscle lipid was reduced by 94% to levels less than 1% of wet tissue weight from early migration to kelt emigration. In kelts, protein appears to be the only remaining somatic energy source for emigration and likely limits post-spawning survival. In chapter 3, we evaluated the profiles of specific fatty acids in white muscle and liver tissues at three intervals. By the time of kelt emigration, all fatty acids were highly depleted suggesting that even structurally important fatty acids are mobilized for energy during prolonged periods of fasting. In chapter 4, we used blood plasma chemistry to compare physiological metrics between a coastal (Situk River, AK) and inland population (Clearwater River, ID) of steelhead kelts. We observed that plasma analytes related to energy storage and nutrition was higher in coastal kelts, whereas electrolytes and plasma enzymes were more variable. Based on emigration distance and selected nutritional metrics derived from plasma chemistry we suggest that coastal kelts are more likely to emigrate successfully to the ocean and repeat spawn.
