4. Growth and Development of King Scallops

Biology of King Scallops

King scallops are bivalves that grow in concentric growth rings, similar to trees. Each year, these concentric rings become more pronounced, creating a visible record of the scallop's growth rate. A large shell of the king scallop can have up to 80 growth rings, indicating an age of up to 8 years.

Stages of Growth

King scallops undergo several stages of growth and development before they reach sexual maturity. During the first few months of life, they grow quickly and can reach a diameter of 1 cm. By the end of their first year, king scallops measure around 6 to 8 cm in diameter. It takes 2 to 3 more years for the scallops to reach their maximum size of around 10 to 15 cm in diameter.

Physical Characteristics of Mature Scallops

Mature king scallops have a hard, ribbed shell with a flat bottom and a ridged top resembling a fan. The color of their shell ranges from creamy white to dark brown, depending on the habitat they are grown in. The inside of the shell is an iridescent blue-gray color. The meat of mature scallops is firm, plump, and sweet, with a delicate sea flavor that makes them a favorite among seafood lovers.

💡 Key Takeaway: King scallops are bivalves growing in concentric growth rings and undergo several stages of growth and development before they become mature. Their maximum size could reach around 10 to 15 cm in diameter.

5. Public Health Concerns Related to King Scallops

Domoic Acid

One concern related to king scallops is the potential presence of domoic acid, a natural toxin produced by certain types of algae. This toxin can accumulate in the tissues of shellfish and other marine creatures, leading to a condition known as amnesic shellfish poisoning (ASP) if consumed by humans.


To mitigate this risk, regulatory bodies have established minimum safe limits for domoic acid in seafood. In the UK, for example, the Marine Management Organisation monitors the levels of this toxin in shellfish, including king scallops, and closures are put in place when levels are deemed unsafe.

Minimum Landing Size

Another issue that relates to public health is the minimum landing size for king scallops. This is the smallest size at which scallops can be legally harvested and sold, and it is based on the age and size at which the scallops are able to reproduce. By setting a minimum landing size, regulators aim to ensure that immature scallops are not harvested and sold, and that stocks are able to replenish themselves sustainably.

Cooking Scallops

Finally, cooking scallops properly is crucial for avoiding potential health risks. When scallops are not cooked thoroughly, they can harbor harmful bacteria that can cause illnesses such as norovirus and vibriosis. To ensure that scallops are safe to eat, it is important to cook them to an internal temperature of at least 145°F (63°C).

💡 Key Takeaway: Consumers of king scallops need to be mindful of public health concerns related to these shellfish, including potential toxins like domoic acid, minimum landing size regulations, and safe cooking practices. By following these guidelines, seafood lovers can enjoy delicious king scallops with peace of mind.
