Description

Abstract: In April 1981 two east coast vessels landed scallops in Coos Bay, Oregon, and stimulated intense fishing effort s by local and non-local vessels. Scallop catch per hour was high initially, but quickly declined, as did landings. Scallop landings and catch per hour stabilized after the third month of the fishery and have been consistent since that time. Results from a logbook program and two cruises showed that scallop distribution and relative abundance in 1981 was similar to 1963 and 1967. Height, weight, and growth parameters varied with depth within a study area, but varied more between study areas. Year -class success also exhibited geographic variation. Spawning time ranges from February through July. Results from gear trials suggest that liners- reduce the catch of adult scallops, but increase the catch of prerecruits. Liner size influences the size distribution of prerecruits caught. A dredge with a 25 mm mesh size liner caught significantly (P < 0. 05) more scallops less than 30 mm in shell height than a dredge with 38 mm mesh size liner. The larger liner caught significantly (P < 0.05) more scallops in the 30-70 mm size range than the smaller liner, indicating a pressure wave effect.
