5203 |a"Abundance and distribution of 14 major species in the Hecate Strait region were examined by season using survey catch rate data. Stable patterns of seasonal distribution were found for spiny dogfish, Pacific sanddab, arrowtooth flounder, and petrale sole. Big skate, rex sole, Pacific halibut, rock sole, Dover sole, and English sole showed some consistencies among surveys, but also enough variability in distribution that no definite conclusions can be drawn at this point. Ratfish, Pacific cod, Pacific ocean perch, and sablefish showed high variability in distribution among surveys. Estimates of standing crop calculated from survey data indicated that the most abundant species in summer were arrowtooth flounder and spiny dogfish, while big skate, ratfish, and English sole predominated in winter. Decreasing abundance between 1984 and 1987 was observed for spiny dogfish, English sole, ratfish, Pacific halibut, rock sole, Pacific sanddab, and petrale sole. Dover sole and rex sole appeared to be increasing in abundance between 1984 and 1987, while sablefish, big skate and arrowtooth flounder were at stable levels of abundance over the same time period"--Abstract, page iii.
