Department of Fisheries and Oceans and published by . This book was released on 1983 with total page 57 pages. Available in PDF, EPUB and Kindle. Book excerpt: The distribution and abundance of fish in the Minto Creekdrainage, Mayo, Yukon Territory, was investigated between August6 and 10, 1982. The study was carried out to obtain preliminaryinformation on the effects of placer mining on the distribution, feeding and condition of Arctic grayling (Thymallus arcticus). It is concluded that a major part of the Minto Creek drainage isused by Arctic grayling but placer mining activities tend toconfine underyearlings to the less turbid waters. Despite thepresence of relatively high densities of prey (chironomid larvae)for underyearling Arctic grayling in the placer-mined HighetCreek, grayling were scarce, only using this tributary assuspended sediment levels decreased in response to a reduction ofplacer mining activities.
