Farmed scallops are a more sustainable option than wild-caught scallops, however the vast majority of scallops on the market are wild caught and rank as either “Some Concerns” or “Avoid” depending on region. Because of how they feed, in some situations scallops may improve water quality, and since they do not rely on fishmeal or fish oil-based feeds, scallop farms have a low impact on marine resources. In addition, scallop farms rarely use fertilizers, antibiotics and other chemicals that could spread into surrounding waters.

Of the two ways to farm scallops, off-bottom culture is preferred. Some scallop farming does have habitat impacts as well as impacts to marine resources because of dredging and the collection of wild larvae (spat). Dredging is the harvest method for wild scallops, which has severe habitat impacts and bycatch concerns.
