Which seafood animals are included in fish processing besides finfish?

In the context of fish processing and food preservation, the term "fish" is broadly used to encompass various edible aquatic animals beyond finfish. These include:1

• Crustaceans: This group includes crabs, lobsters, shrimp, prawns, and crayfish.23
• Mollusks: This category is divided into bivalves (such as clams, oysters, mussels, scallops, and cockles), gastropods (such as snails, abalones, whelks, conch, and periwinkles), and cephalopods (such as squid, octopuses, and cuttlefish).243
• Echinoderms: This group includes sea urchins and sea cucumbers, the latter of which are often marketed as trepang or bêche-de-mer.243
• Other aquatic animals: The broader category of seafood processed for consumption also includes edible jellyfish, sea turtles, and frogs.3

Because these animals are highly perishable, they undergo similar preservation methods as finfish, including freezing, drying, salting, smoking, and fermentation, to maintain quality and safety.1563
