This book was released on 1996 with total page 37 pages. Available in PDF, EPUB and Kindle. Book excerpt: This study was designed to describe aspects of the life history strategies of spring chinook salmon in the Grande Ronde basin. During the past year we focused on rearing and migration patterns of juveniles and surveys of spawning adults. The specific objectives for the early life history portion of the study were: Objective 1, document the annual in-basin migration patterns for spring chinook salmon juveniles in the upper Grande Ronde River, including the abundance of migrants, migration timing and duration; Objective 2, estimate and compare smolt survival indices to mainstem Columbia and Snake River dams for fall and spring migrating spring chinook salmon; Objective 3 initiate study of the winter habitat utilized by spring chinook salmon in the Grande Ronde River basin. The specific objectives for the spawning ground surveys were: Objective 4, conduct extensive and supplemental spring chinook salmon spawning ground surveys in spawning streams in the Grande Ronde and Imnaha basin, Objective 5; determine how adequately historic index area surveys index spawner abundance by comparing index counts to extensive and supplemental redd counts; Objective 6, determine what changes in index areas and timing of index surveys would improve the accuracy of index surveys; Objective 7, determine the relationship between number of redds observed and fish escapement for the Grande Ronde and Imnaha river basins.

This book was released on 2016-09-27 with total page 56 pages. Available in PDF, EPUB and Kindle. Book excerpt: Excerpt from Spawning Areas and Abundance of Chinook Salmon (Oncorhynchus Tshawytscha) In the Columbia River Basin: Past and Present Spawn in intermediate and large tribu taries and in middle reaches of the main stem. Spring-run chinook salmon Spawn in some lower Columbia River tributaries such as the Willamette, Cowlitz, and Kalama Rivers. They also are distributed in middle tributaries of the Columbia and Snake Rivers. (fall-run chinook salmon, discussed later in the report, share spawning grounds in some sections of the Cowlitz and Kalama Rivers.) These are not all of the areas in which such duplications occur but are cited as examples. About the Publisher Forgotten Books publishes hundreds of thousands of rare and classic books.

Download or read book Investigations Into the Early Life History of Naturally Produced Spring Chinook Salmon in the Grande Ronde Riiver Basin written by and published by . This book was released on 1997 with total page 36 pages. Available in PDF, EPUB and Kindle. Book excerpt: Historically, the Grande Ronde River produced an abundance of salmonids including stocks of spring, summer and fall chinook salmon, sockeye salmon, coho salmon, and summer steelhead. During the past century, numerous factors have caused the reduction of salmon stocks such that only sustainable stocks of spring chinook salmon and summer steelhead remain. The sizes of spring chinook salmon populations in the Grande Ronde River basin also have been declining steadily and are substantially depressed from estimates of historic levels. In addition to a decline in population abundance, a reduction of spring chinook salmon spawning distribution is evident in the Grande Ronde River basin. Numerous factors are thought to contribute to the decline of spring chinook salmon in the Snake River and its tributaries. These factors include passage problems and increased mortality of juvenile and adult migrants at mainstem Columbia and Snake river dams, overharvest, and habitat degradation associated with timber, agricultural, and land development practices. This study was designed to describe aspects of the life history strategies exhibited by spring chinook salmon in the Grande Ronde River basin. During the past year the focus was on rearing and migration patterns of juveniles in the upper Grande Ronde River and Catherine Creek. The study design included three objectives: (1) document the annual in-basin migration patterns for spring chinook salmon juveniles in the upper Grande Ronde River and Catherine Creek, including the abundance of migrants, migration timing and duration; (2) estimate and compare smolt survival indices to mainstem Columbia and Snake river dams for fall and spring migrating spring chinook salmon; and (3) determine summer and winter habitat utilization and preference of juvenile spring chinook salmon in the upper Grande Ronde River and Catherine Creek.
