5203 |a"A lingcod hook and line survey was conducted in the Gulf Island area of the Strait of Georgia during October-December 1985. The purpose of the survey was to compare research CPUE with the CPUE determined from sales records of the commercial hook and line fishery. This report presents an analysis of the first year of a proposed 3-yr study. We tested the effects of fishing method, depth, sea condition, cloud cover, time of day, current and tide on CPUE. Fishing method and depth had a significant effect on CPUE for lingcod and rockfish. All other factors had an insignificant effect on CPUE. A higher proportion of lingcod and larger lingcod and rockfish were caught by the commercial fishing method. Depth had a significant effect on species composition but not on the size of lingcod"--Abstract, page iii.
