The sea scallop (Placopecten magellanicus) occurs only in the northwest Atlantic from Virginia north to Labrador. Within this area, scallops are concentrated in persistent, geographically discrete aggregates or "beds", many of which support valuable commercial fisheries. The larger beds are found offshore and in the Bay of Fundy. Scallops exhibit varying growth rates and meat yields in different beds and in different areas of large beds.

Unlike many commercial scallop species, the sea scallop has separate sexes. Male scallops develop a white gonad in the summer months, while female gonads are bright red. Eggs and sperm are released into the water where fertilization takes place. Spawning begins in late August to early September, and the larvae drift in the water column for almost a month before settling to the bottom.
