Bathymetric distributions of Pacific ocean perch (Sebastes alutus) off British Columbia. I. Mean length-at-age versus depth for specimens caught by on-bottom trawl off northwest Queen Charlotte Islands and in Hecate Strait and Queen Charlotte Sound, 1966-78

This report investigates the relationship of mean-length-at-age versus the depth for the Pacific ocean perch (Sebastes alutus), based on on-bottom trawl catches on important trawling grounds in the British Columbia waters. Catch samples from both the R/V G.B. Reed, a side-trawler (1966-84) and several commercial trawlers (1978-97) were utilized. Important grounds, for which adequate data were available, were off the northwest coast of the Queen Charlotte Islands (MSAs 1W and 2AW), Moresby Gully (south Hecate Strait and north Queen Charlotte Sound), and Goose Island Gully (Queen Charlotte Sound).
