Description

Abstract: Results of a November 1981 cooperative research cruise off the Oregon coast aboard the National Marine Fisheries Service vessel the R/V Chapman indicated that weathervane scallops (Pecten [Patinopecten) caurinus) off Coos Bay. Oregon had significantly different (P = 0.05) population characteristics than scallops off Tillamook Head, Oregon. One strong year-class dominated the Coos Bay beds whereas recruitment was more uniform off Tillamook Head. Scallops in the Coos Bay area were younger and larger than scallops in the Tillamook area. Coos Bay scallop mean age was 5.7 ± 1.5 yrs and mean height was 119.9 ± 10.0mm. Tillamook scallops were 6.8 ± 1.8 yrs old with a mean height of 109.0 ± 7.7mm. Relative abundance of scallops was greatest in 45-60 fm in both areas. Population characteristics of males and females were not significantly different (P > 0.05) and all scallops were dioecious. Miscellaneous invertebrates and small fish comprised almost 50% of the total weight of the incidental catch.
