Difference Between Bay Scallops and Sea Scallops - Comparison Summary

What are Bay Scallops

Bay scallops are the scallops found in bays, estuaries, and cold and shallow waters of the East coast. Bay scallops are typically smaller in size than sea scallops – about half an inch wide (this is about 1/3 the size of sea scallops). The weight can range from 50 to 100 scallops per pound. Although they are smaller in size, they have a sweeter flavour and have tender meat. They are typically used in seafood stews and casseroles. They are also less expensive than sea scallops.

When considering the structure of bay scallops, what we call bay scallop is the adductor muscle that hinges the two shells. This is why bay scallops have a small size. The rest of the bay scallop is the coral (which is the ovary), and this part is inedible. Most of the scallops sold in the US today are imported from Mexico and China, as their domestic scallop population have decreased in recent years.

What are Sea Scallops

As their name suggests, sea scallops are found in deep ocean waters around the world. They are usually found up to up to 200 meters deep in cold seawater. In the United States, sea scallops are usually found in the Northwest Atlantic Ocean, from Newfoundland to Cape Hatteras, North Carolina.

Sea scallops are larger than bay scallops, usually more than three times larger. They can be up to two inches in diameter. They are also a little chewier than bay scallops. If we consider their weight, there are about 20 to 30 scallops in a pound of sea scallops. When you order seared scallops in a restaurant, you will usually get sea scallops.
