Some problems exist with this species' status or catch methods, or information is insufficient for evaluating. Scallop, Weathervane

The Weathervane Scallop is a large scallop, growing up to 25 cm in shell height, distributed from central California to Alaska. They grow fast and reach sexual maturity by 4 years, but form aggregations in discrete areas, making them vulnerable to capture.

Most Weathervane Scallops are caught in the Gulf of Alaska and Bering Sea, where fishery management has established catch limits and regulations to control fishing pressure.

Although current catch levels appear to be sustainable, abundance levels of Weathervane Scallops remain largely unknown.

Weathervane Scallops are captured using scallop dredges, which result in moderate levels of bycatch, but can cause substantial habitat damage. However, several regions have been closed to fishing to reduce habitat impacts.
