Book Synopsis Salmonid Field Protocols Handbook by : David H. Johnson
Download or read book Salmonid Field Protocols Handbook written by David H. Johnson and published by . This book was released on 2007 with total page 504 pages. Available in PDF, EPUB and Kindle. Book excerpt: This is the first publication to collect, standardize, and recommend a scientifically rigorous set of field protocols for monitoring and assessing salmon and trout populations. Includes five additional techniques that can be used with any of the 13 principle methods to supplement information gathered.Over four dozen fisheries experts throughout the U.S. Pacific Northwest and beyond contributed their time to pick, write, and review the most reliable protocols for enumerating salmonids in the field. Presented in an easy to use format, each of the 18 peer-reviewed protocols covers objectives, sample design, data handling, personnel and operational requirements, and field and office techniques, including survey forms.Standardized monitoring protocols will improve data reliability, maximize opportunities for data sharing and data set comparability, and ultimately improve the ability to assess status and trends. The Handbook will also support consistency in data collection for salmonids at the international level.

Book Synopsis Winter-run Chinook Salmon in the Sacramento River, California with Notes on Water Temperature Requirements at Spawning by : Daniel W. Slater
Download or read book Winter-run Chinook Salmon in the Sacramento River, California with Notes on Water Temperature Requirements at Spawning written by Daniel W. Slater and published by . This book was released on 1963 with total page 20 pages. Available in PDF, EPUB and Kindle. Book excerpt: Salmon specialists throughout the Pacific Coast indicate that the winter-run Chinook salmon is restricted to California's Sacramento River system. The characteristics and habits of the race are unique in the following respects: Fresh-water holding period, December to April; spawning period, April into July. The up-migration is concurrent with the late segments of the fall run, but the adults are distinguishable by the green condition of the gonads. The down-migration is concurrent with that of the spring-run fry, but the migrants are 2-inch or larger fingerlings. Evidence is lacking to determine whether there is an earlier down-migration of fry. The race appears to hold great promise as a stock to be introduced into areas where May-August temperatures are 42.5 degrees - 57.5 degrees F., for it supports superb angling during the fresh-water holding period. Water temperatures in May through August are seen as the factor limiting the natural extension of the range of the race.
Book Synopsis Analytical Approaches to Assessing Recovery Options for Snake River Chinook Salmon by : Phaedra Budy
Download or read book Analytical Approaches to Assessing Recovery Options for Snake River Chinook Salmon written by Phaedra Budy and published by Createspace Independent Pub. This book was released on 2012-08-23 with total page 92 pages. Available in PDF, EPUB and Kindle. Book excerpt: The depressed status of Snake River stocks of chinook and steelhead and the recent listings of many salmon stocks in the Columbia Basin have led to several analytical evaluations and management advice aimed at recovery of these stocks. These different analytical reviews address the effectiveness of different hydrosystem options as well as the potential for recovery through improvements that increase survival at other life stages (e.g., habitat, harvest). Hydrosystem options evaluated included status quo, maximizing transportation, and the option of breaching the lower four dams on the Snake River (also called drawdown and natural river options), the main topic of the Lower Snake River Juvenile Salmon Migration Feasibility Report / Environmental Impact Statement (USACE). The first review was completed by PATH (Plan for Testing and Analyzing Hypotheses), an open forum composed of modelers, fishery biologists and statisticians from all three states (Oregon, Washington, and Idaho), the federal government (Army Corps of Engineers (USACE), US Fish and Wildlife Service (USFWS), National Marine Fishery Service (NMFS), Bonneville Power Administration (BPA), the treaty tribes of the Columbia Basin (represented by the Columbia River Inter-tribal Fish Commission -CRITFC), and the Northwest Power Planning Council (NPPC). The PATH approach was based on a decision analysis that showed which management actions are the most robust to remaining uncertainties (i.e. the least risky) and allows a decision to be made with full consideration of uncertainty and risk. PATH analyses were followed by the NMFS effort called CRI- the Cumulative Risk Initiative. CRI analyses explore the demographic effects of hypothetical reductions in mortality at different life stages based on current conditions. PATH and CRI analyses were followed by an analytical comparison of their approaches and results completed by a sub group of PATH composed of scientists from the states of Oregon, Idaho, Washington, CRITFC, and the USFWS. In addition, specific analyses have considered the potential for improvement at certain life stages (e.g., freshwater spawning and rearing; Petrosky et al., in press) and key uncertainties that affect the likely effectiveness of dam breach (e.g., delayed hydrosystem mortality; Budy et al., in review). This annex synthesizes analyses and results PATH, NMFS CRI, and comparative and follow-up analyses which have been completed since and are summarized here and described in greater detail elsewhere. Although the results vary somewhat among approaches, all available science appears to suggest that dam breach has the greatest biological potential for recovering Snake River salmon and steelhead.

Book Synopsis Fall Chinook (Oncorhynchus Tshawytscha) by : Jim Waldvogel
Download or read book Fall Chinook (Oncorhynchus Tshawytscha) written by Jim Waldvogel and published by . This book was released on 2006 with total page 48 pages. Available in PDF, EPUB and Kindle. Book excerpt: Age analysis for 22 years (1980 excluded) showed that the overall percentages for female spawners was 53% (4-year olds), 38% (3-year olds), and 9% (5-year olds). The age composition of male spawners showed a high degree of variability throughout the study. Male chinook of age 2, 3 and 4 were dominant annually, but 5- and 6- year old fish were present in most spawning seasons. All chinook carcasses from which scales were collected were also measured for length (over 120 samples in 22 years). Decreases in mean length were documented for all age classes for each of the El Nino episodes that occurred during the study (1982-1984; 1992-1993; 1997-1998). The decreases in mean length appeared to carry forward for each cohort's age class. The total number of chinook redds was tabulated by counting "fresh" redds during weekly spawning surveys. The mean number of redds was 117 for the 23-year period with a mean of 0.9 redds per adult salmon or 1.8 redds per female.

Book Synopsis Idaho's Chinook Salmon by : Deirdre A Abrams
Download or read book Idaho's Chinook Salmon written by Deirdre A Abrams and published by . This book was released on 2020-12-19 with total page 58 pages. Available in PDF, EPUB and Kindle. Book excerpt: Wild Chinook salmon, some migrating more than 900 miles to the ocean from the high mountains of Idaho, once made up nearly 50% of the Columbia River Basin's salmon runs. In 2020, and over the last twenty years, wild Chinook in Idaho have been in crisis, placed on the endangered species list, and face the growing threat of extinction. In fact, only 2 % of Idaho's wild Chinook population remains. This is not only a crisis for this Idaho salmon but also for biodiversity in the Pacific Northwest. Snake River Chinook salmon are culturally important to many indigenous peoples and are the main source of food for the Southern Resident killer whales (orcas) of Puget Sound; therefore, the plight of Chinook salmon is adversely affecting native traditions and sustenance, and also the Southern Resident orcas, which are also on the endangered species list. Because Chinook salmon who originate in Idaho travel the farthest through the Columbia River Basin to the Pacific Ocean... and back... than any other Chinook population in the lower 48 states, the focus of this book is on them and their miraculous, obstacle-filled migration. It is for the fish and young people that I write this book- in hopes of enlightening and inspiring kids all over the country, not just in Idaho, to learn how very special these brave salmon are and to join me in protecting them!
