Rock Scallop – Oregon Conservation Strategy

Overview

Species Common Name Rock Scallop
Species Scientific Name Crassadoma gigantea

Ecoregions

Nearshore

The Nearshore ecoregion includes a variety of habitats ranging from submerged high-relief rocky reefs to broad expanses of intertidal mudflats in estuaries and hosts a vast array of fish, invertebrates, marine mammals, birds, plants, and micro-organisms. This ecoregion encompasses the area from the outer boundary of Oregon’s Territorial Sea to the supra-tidal zone, and up into the estuaries.

Special needs

Rock scallops require rocky substrates and occur primarily in subtidal areas.

Limiting factors

Rock scallops are long-lived but slow to mature.

Data gaps

Determine longevity and fecundity. Assess spatial distribution and abundance in shallow subtidal habitat.

Conservation actions

Monitor status of populations at index sites. Manage for sustainable harvest. Gather information to fill data gaps.
