Book Description
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.
