Available in PDF, EPUB and Kindle. Book excerpt: A study of wild spring chinook salmon was conducted in the John Day River, Oregon: (1) recommend harvest regulations to achieve escapement goals in the John Day River; (2) recommend adtustments in timing of fish passage operations at Columbia River dams that will increase survival of John Day migrants; (3) recommend habitat or environmental improvements that will increase production of spring chinook salmon; (4) determine escapement goals for wild spring chinook salmon in the John Day River; and (5) recommend procedures for hatchery supplementation in the John Day River in the event it becomes necessary to artificially maintain the run of spring chinook salmon. Juveniles were captured as smolts during migration and as fingerlings during summer rearing. Juveniles were coded-wire tagged, and recoveries of tagged adults were used to assess contribution to ocean and Columbia River fisheries, timing of adult migrations through the Columbia River in relation to fishing seasons, and age and size of fish in fisheries. Scoop traps and seines were used to determine timing of smolt migrations through the John Day River. In addition, recoveries of tagged smolts at John Day Dam, The Dalles Dam, and Jones Beach were used to determine migration timing through the Columbia River. We examined freshwater life history of spring chinook salmon in the John Day River and related it to environmental factors. We looked at adult holding areas, spawning, incubation and emergence, fingerling rearing distribution, size and growth of juveniles and scales. Escapement goals fo the John Day River as well as reasons for declines in John Day stocks were determiend by using stock-recruitment analyses. Recommendations for hatchery supplementation in the John Day were based on results from other study objectives.

This book was released on 1999 with total page 31 pages. Available in PDF, EPUB and Kindle. Book excerpt: The John Day River basin supports one of the healthiest naturally-produced populations of spring chinook in the mid-Columbia River basin. The study of life history and natural escapement conducted from 1978 to 1985 (Lindsay et al. 1986) provided valuable information on production and productivity of the John Day River spring chinook. With the exception of two years since completion of the study in 1985 (1989 and 1995), spring chinook spawning surveys were conducted in index areas only and have not provided adequate information to assess age composition, progeny-to-parent production values, and estimate natural spawning escapement. The PATH project (Marmorek and Peters 1996) has identified the John Day basin spring chinook as an index population for assessing the effects of alternative future management actions on salmon stocks in the Columbia Basin. To meet the data needs as an index stock, sufficient annual estimates of spawner escapement, age composition, and smolt-to-adult survival are essential. There is need to determine the annual spawner escapement and age composition for the John Day basin spring chinook to provide us the ability to estimate progeny-to-parent production for each brood year. This need can be met by expanding the annual chinook spawning surveys, estimating the annual escapement, and determining age composition by scale pattern analyses. This project provides information as directed under two measures of the Columbia Basin Fish and Wildlife Program (NPPC 1994). Measure 4.3C specifies that the key indicator populations should be monitored to provide detailed stock status information. In addition, measure 7.1C identifies the need for collection of population status, life history, and other data on wild and naturally spawning populations. This project was developed in direct response to recommendations and needs of the PATH project, the Fish and Wildlife Program, and the Columbia Basin Fish and Wildlife Authority Multi-Year Implementation Plan.
