Coho colonization potential of the Cowichan-Koksilah Watershed : a habitat evaluation / by T. Burns and B.D. Tutty.: Fs97-4/1865E-PDF

"Reaches of the Cowichan-Koksilah system situated above barriers were assessed for their suitability as coho rearing habitat in the arid late summer of 1985. Discharge and temperature were recorded, along with structural characteristics of specified stream sections. An estimate of 6,383,900 M² of viable habitat was identified with a potential smolt yield of approximately 500,000 or 2.5 million based on two different production models. Dollar value at harvest is annually estimated near $1 million and $5 million (1984) respectively, depending on the production model employed. More conservative or liberal production assumptions can be applied to the habitat data contained in the report. Development of cost models and possible strategies would be part of a Cowichan-Koksilah watershed production plan that would embrace abalanced multistock rebuilding/enhancement effort in cooperation with the Provincial Fisheries Branch"--Abstract, page iii.
