finfish
True fish, basically
Finfish refers to fish with fins and a backbone—the familiar scaly creatures—as distinguished from shellfish like crabs, lobsters, and clams.
The term appears mainly in fishing regulations, seafood industry contexts, and scientific writing where the distinction matters: The harvest includes finfish and shellfish.
In everyday speech, people just say fish.
