Book Synopsis The Behavior and Ecology of Pacific Salmon and Trout by : Thomas P. Quinn
Download or read book The Behavior and Ecology of Pacific Salmon and Trout written by Thomas P. Quinn and published by UBC Press. This book was released on 2011-11-01 with total page 392 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Behavior and Ecology of Pacific Salmon and Trout explains the patterns of mate choice, the competition for nest sites, and the fate of the salmon after their death. It describes the lives of offspring during the months they spend incubating in gravel, growing in fresh water, and migrating out to sea to mature. This thorough, up-to-date survey should be on the shelf of everyone with a professional or personal interest in Pacific salmon and trout. Written in a technically accurate but engaging style, it will appeal to a wide range of readers, including students, anglers, biologists, conservationists, legislators, and armchair naturalists.

This book was released on 2012-02-02 with total page 681 pages. Available in PDF, EPUB and Kindle. Book excerpt: The symposium "Pacific Salmon and Their Ecosystems: Status and Future Options',' and this book resulted from initial efforts in 1992 by Robert J. Naiman and Deanna J. Stouder to examine the problem of declining Pacific salmon (Oncorhynchus spp.). Our primary goal was to determine informational gaps. As we explored different scientific sources, state, provincial, and federal agencies, as well as non-profit and fishing organizations, we found that the information existed but was not being communicated across institutional and organizational boundaries. At this juncture, we decided to create a steering committee and plan a symposium to bring together researchers, managers, and resource users. The steering committee consisted of members from state and federal agencies, non-profit organizations, and private industry (see Acknowledgments for names and affiliations). In February 1993, we met at the University of Washington in Seattle to begin planning the symposium. The steering committee spent the next four months developing the conceptual framework for the symposium and the subsequent book. Our objectives were to accomplish the following: (1) assess changes in anadromous Pacific Northwest salmonid populations, (2) examine factors responsible for those changes, and (3) identify options available to society to restore Pacific salmon in the Northwest. The symposium on Pacific Salmon was held in Seattle, Washington, January 10-12, 1994. Four hundred and thirty-five people listened to oral presentations and examined more than forty posters over two and a half days. We made a deliberate attempt to draw in speakers and attendees from outside the Pacific Northwest.
Book Synopsis Biology of Juvenile Sockeye Salmon Resident in Chignik River, Alaska by : Ronald Albert Iverson

This book was released on 1966 with total page 144 pages. Available in PDF, EPUB and Kindle. Book excerpt: The life history of juvenile sockeye salmon (Oncorhynchus nerka) resident in Chignik River, Alaska, represents a departure from the lacustrine, pelagic existence typical of juveniles of this species. For this reason, the distribution, relative abundance in different parts of the river, growth, and upstream and downstream movements of juvenile sockeye in the river were studied during the summers of 1963 and 1964. The objectives of the study were to gain information on the possible origins of juvenile sockeye resident in Chignik River, and on the role of Chignik River in production of sockeye salmon. Distribution and abundance were estimated by seining and underwater observation. Juvenile sockeye appeared to be restricted to quiet waters along the shore. Catches of sockeye fry tended to increase through the summer, whereas catches of yearlings decreased. Smolts were taken in significant numbers only in June and July. early summer, large numbers of yearling sockeye were concentrated in Chignik River just below the outlet of Chignik Lake. In sockeye fry and yearlings captured in the lower river were generally larger than those captured in the upper river. Juvenile sockeye in the upper river grew slower than those in most other parts of the watershed. Scale analysis of sockeye salmon spawning in Chignik River showed that these fish entered the ocean at a larger size than did fish reared in Chignik Lake or Chignik River. This suggests that at least part of the progeny of river spawners do not remain in the river, but descend as fry to the brackish estuary, where growth conditions are superior. Upstream movement of schools of yearling sockeye was observed in the upper portions of the river. Such a movement has been observed many times in Chignik River in past years and has at times involved large numbers of fish. Schools of yearling sockeye have been observed to enter Chignik Lake. Fish of the same size group were captured while moving downstream at the lake outlet at night, suggesting a circular movement involving displacement of fish into the river at night and a positive rheotactic response causing them to re-enter the lake during the day. Juvenile sockeye salmon resident in Chignik River may include both progeny of river spawners, and fish which have moved down from Chignik Lake; Chignik Lake is probably the more important source. Chignik River is judged to have a minor role in the production of sockeye salmon, relative to the other rearing areas in the watershed.
