1988 research catch and effort data on nearshore reef-fishes in British Columbia Statistical Areas 12 and 13 / by L.J. Richards, C.M. Hand and J.R. Candy.: Fs97-4/2000E-PDF

"In 1984 we began a research program to fulfill the need for stock assessments of nearshore reef-fishes in the Strait of Georgia. The 1988 results from statistical areas 12 and 13 are presented in this report, and are compared with the 1986 and 1987 results from the same areas. Research CPUE data were collected by angling with trolling rods and reels, using frozen herring as bait. Three depth intervals (5-40 m, 41-70 m, and 71-100 m) were fished at most sites. Rockfish CPUE was higher in 1988 than in 1986-87 for both areas 12 and 13. Mean rockfish CPUE in area 13 doubled between 1987 and 1988, perhaps due to the closure of Discovery Passage to the commercial rockfish fishery. In among-area comparisons, CPUE was highest for the Discovery Passage region of area 13 over 5-40 m. Quillback rockfish, copper rockfish and lingcod were the dominant species in the catch. Species composition varied with depth and area, with the largest number of species caught in area 12. Quillback rockfish size increased with depth in all areas. Quillback rockfish from area 12 were larger than quillback rockfish from area 13"--Abstract, page iii.
