If chicken is poultry what fish?

This is a bit of a trick question! While chicken is considered poultry, there isn't a single word that describes all fish in the same way.

Here's why:

* Poultry is a specific category of birds raised for meat or eggs.

* Fish is a much broader category, encompassing a vast diversity of aquatic animals.

So, there's no direct equivalent to "poultry" for fish.

However, you could use these terms depending on the context:

* Seafood: This is a general term for edible aquatic life.

* Finfish: This refers to fish with fins, as opposed to shellfish.

* Crustaceans: A group of aquatic animals with a hard exoskeleton, such as crabs, lobsters, and shrimp.

* Mollusks: A group of aquatic animals with a soft body, often protected by a shell, like oysters, clams, and squid.
