Scallops are a delicacy enjoyed by many around the world, prized for their tender flesh and sweet flavor. However, not all scallops are created equal. Two of the most common types of scallops are sea scallops and bay scallops, each with its unique characteristics, habitats, and culinary uses. In this article, we will delve into the world of scallops, exploring the differences between sea scallops and bay scallops, and what sets them apart.
What are Scallops?
Before we dive into the differences between sea scallops and bay scallops, let’s first understand what scallops are. Scallops are a type of marine bivalve mollusk, belonging to the family Pectinidae. They are characterized by their fan-shaped shells, which are typically white or cream-colored, with a series of radiating ribs. Scallops are found in oceans around the world, from shallow coastal waters to deep-sea environments.
Scallop Anatomy
Scallops have a unique anatomy that allows them to thrive in their underwater environment. They have a pair of hinged shells, which they use to protect themselves from predators and to filter food particles from the water. Scallops also have a series of tentacles, called cirri, which they use to sense their surroundings and capture food particles. The most distinctive feature of scallops, however, is their ability to swim using a unique form of jet propulsion. By clapping their shells together, scallops can create a fast-moving current that propels them through the water.
Sea Scallops vs Bay Scallops: What’s the Difference?
Now that we have a basic understanding of scallops, let’s explore the differences between sea scallops and bay scallops. The main difference between the two is their habitat and size.
Sea Scallops
Sea scallops, also known as Atlantic sea scallops, are found in the deep waters of the Atlantic Ocean, from Canada to North Carolina. They are the largest type of scallop, with shells that can grow up to 4 inches (10 cm) in diameter. Sea scallops are harvested using dredges or trawls, which can be damaging to the seafloor and the surrounding ecosystem.
Characteristics of Sea Scallops

What is the main difference between sea scallops and bay scallops?
The primary difference between sea scallops and bay scallops lies in their size, habitat, and flavor profile. Sea scallops are generally larger and more widely available than bay scallops. They are found in deeper waters, typically between 100 and 400 feet deep, and have a milder flavor. On the other hand, bay scallops are smaller, sweeter, and have a more delicate flavor. They are found in shallower waters, usually in bays, estuaries, and coastal areas.
The difference in size and flavor is due to the distinct habitats and diets of the two types of scallops. Sea scallops feed on plankton and small crustaceans, which gives them a milder flavor. Bay scallops, on the other hand, feed on algae and small invertebrates, which contributes to their sweeter taste. Understanding these differences can help you make informed decisions when choosing between sea scallops and bay scallops for your culinary needs.
Where are sea scallops typically found?
Sea scallops are typically found in the North Atlantic Ocean, specifically in the waters off the eastern coast of the United States and Canada. They are commonly harvested in areas such as the Gulf of Maine, the Mid-Atlantic, and the Canadian Maritimes. Sea scallops are also found in other parts of the world, including Europe and Japan, but the North Atlantic is their primary habitat.
The specific location where sea scallops are found can affect their flavor and texture. For example, sea scallops from the Gulf of Maine are known for their tender flesh and sweet flavor, while those from the Mid-Atlantic may have a slightly firmer texture. Knowing the origin of your sea scallops can help you appreciate their unique characteristics and flavor profile.
What is the average size of a bay scallop?
The average size of a bay scallop is typically around 1-2 inches (2.5-5 cm) in diameter. However, some bay scallops can grow up to 3 inches (7.5 cm) or more in size. The size of bay scallops can vary depending on factors such as their age, diet, and habitat.
Despite their smaller size, bay scallops are highly prized for their sweet flavor and tender texture. They are often used in dishes where their delicate flavor can shine, such as in salads, sautés, and pasta dishes. Bay scallops are also a popular choice for sushi and sashimi due to their sweet flavor and firm texture.
How do sea scallops and bay scallops differ in terms of flavor?
Sea scallops and bay scallops differ significantly in terms of flavor. Sea scallops have a milder flavor, often described as sweet and tender. They have a more neutral taste, which makes them a versatile ingredient in many dishes. Bay scallops, on the other hand, have a sweeter and more delicate flavor. They have a more pronounced taste, which is often described as sweet and nutty.
The difference in flavor between sea scallops and bay scallops is due to their distinct habitats and diets. Sea scallops feed on plankton and small crustaceans, which gives them a milder flavor. Bay scallops, on the other hand, feed on algae and small invertebrates, which contributes to their sweeter taste. Understanding these differences can help you choose the right type of scallop for your culinary needs.
Can I substitute sea scallops for bay scallops in a recipe?
While it’s possible to substitute sea scallops for bay scallops in a recipe, it’s not always the best option. Sea scallops are generally larger and have a milder flavor than bay scallops, which can affect the overall flavor and texture of the dish. If you’re looking to substitute sea scallops for bay scallops, it’s best to use a smaller sea scallop or to adjust the cooking time and method to accommodate the larger size.
That being said, there are some recipes where sea scallops can be substituted for bay scallops without affecting the overall flavor and texture. For example, in dishes where the scallops are cooked in a strong-flavored sauce or where they’re seared and served as a main course, sea scallops can be a good substitute. However, in dishes where the delicate flavor of bay scallops is the star, it’s best to use the real thing.
How do I store and handle scallops to maintain their freshness?
To maintain the freshness of scallops, it’s essential to store and handle them properly. Scallops should be stored in a covered container, covered with ice, and kept refrigerated at a temperature below 40°F (4°C). They should be used within a day or two of purchase, as they are highly perishable.
When handling scallops, it’s essential to be gentle to avoid damaging their delicate flesh. Scallops should be rinsed under cold water, patted dry with paper towels, and cooked immediately. They should not be washed in hot water or soaked in water, as this can cause them to become tough and rubbery. By handling and storing scallops properly, you can maintain their freshness and ensure they’re safe to eat.
Are scallops a sustainable seafood choice?
Scallops can be a sustainable seafood choice, depending on the fishing method and location. Some scallop fisheries are certified as sustainable by organizations such as the Marine Stewardship Council (MSC), which ensures that the fishery is well-managed and has minimal impact on the environment.
However, not all scallop fisheries are sustainable. Some scallop fisheries use dredging methods that can damage the seafloor and harm other marine species. Additionally, some scallop fisheries may have high bycatch rates, which can harm other marine species. By choosing scallops from certified sustainable fisheries, you can help promote sustainable seafood practices and reduce your environmental impact.
