Download or read book 2003 Arctic Grayling Thymallus Arcticus Fry Surveys in the Ingenika River written by and published by . This book was released on 2004 with total page 45 pages. Available in PDF, EPUB and Kindle. Book excerpt: As part of ongoing investigations to determine the status of Arctic grayling in the Williston watershed in northern British Columbia, a large tributary stream of the Williston Reservoir was examined to determine Arctic grayling distribution, relative abundance, and habitat use. This report presents findings of electrofishing surveys that looked for the presence of Arctic grayling in the Ingenika River watershed. Observations of grayling fry habitat use are compared to studies conducted on other rivers in the Williston watershed. Results are also presented from angling surveys that collected information on adult grayling distribution.

This report presents findings of electrofishing surveys that looked for the presence of Arctic grayling in the Omineca and Osilinka rivers. Observations of grayling fry habitat use are compared to studies conducted on the Table & Anzac rivers in the Parsnip River drainage of the Williston watershed. Results are also presented from angling surveys that collected information on adult grayling distribution.

Download or read book 1998 Arctic Grayling Thymallus Arcticus Surveys in the Table Anzac and Parsnip Rivers written by and published by . This book was released on 2001 with total page 54 pages. Available in PDF, EPUB and Kindle. Book excerpt: This report describes a 1998 study of Arctic grayling life history & habitat utilization on three rivers in the Williston Reservoir watershed of British Columbia. Introductory sections describe the study area (the Table River, Anzac River, and the 25-kilometre section of the Parsnip River between the Table & Anzac rivers) and methodology. The research included collection of water temperature data, an egg deposition survey, fry distribution surveys, sampling of young of the year, sampling of suitable habitats, mark recapture studies, and collection of biological information from sampled grayling. Results are presented & discussed with regard to water temperature trends, abundance & distribution of grayling fry, fish density, habitat utilization, characteristics of suitable habitats, abundance of adult grayling & other sport fish (trout, whitefish), age class distribution of grayling, and juvenile growth rates. Based on the findings, management implications & research needs are discussed.
