Plural of Fish

The animal noun “fish” has two recorded plural forms, “fish” and “fishes.” The reviewed dictionaries record both without establishing a universal rule that one must always mean multiple species. Separately, “fish” can be uncountable when it means fish as food. Choose the construction from the actual sense and any controlling specialist/style convention.

Quick answer

Both “fish” and “fishes” are dictionary-recorded plurals of “fish.” “Fish” is also uncountable when it means the food.
