Includes bibliographical references (pages 7-8). "In 1984 we began a research fishing program based on the need for stock assessments of nearshore reef-fishes in the Strait of Georgia. Five cruises were completed in MSA 15 and 16 during the 1984 field season. A stratified random design was used to choose fishing sites within these statistical areas. Three depth strata (<40 m, 40-70 m, and 70-100 m) were fished at most sites. Fishing during the first cruise was conducted by automated jig. Standard angling gear (trolling rod and reel) was used on the remaining cruises. Dogfish, copper rockfish, quillback rockfish, yelloweye rockfish and lingcod were the dominant species in the catch. Species composition varied with the depth, statistical area and vessel used for fishing. CPUE was consistently higher with the use of bait herring than with a stingsilda, when both methods were performed concurrently. Herring CPUE varied significantly with sea surface conditions and time of day. Depth and tidal phase had no significant effect. Raw data on catch, effort and associated set information and a description of a standardized methodology are presented in this report"--Abstract, page iii. Includes abstracts in English and French.
