Description

Abstract: Oyster mortality data collected from suspended trays at three subtidal locations in Yaquina Bay disclosed an unusually high 26.5% Pacific oyster (Crassostrea gigas) mortality during the study year. Almost all of this mortality resulted from culling damage which occurred previous to introduction of the oysters into trays. Native oyster mortality was 22.1%, 1.5% higher than the average mortality of the previous 4 years. Mortality of bay mussels was 44.2%. No evident causes for this high mortality were noted. Mussels were not monitored in previous years. Pacific oyster mortality in intertidal trays was 7.3% at the Tillamook Bay station; 6.7% at the Coos Bay station. A total of approximately 1,750 oysters and mussels were collected during the study year and sent to the National Marine Fisheries Service (NMFS) Oxford Laboratory for histological examination.
