What is the exact meaning of the word "fish" in the modern English?
Usually it is translated into Russian as "рыба" but as far as I understand "рыба" is English "fin fish"
I've noticed that many native English speakers when they say "fish" they mean any underwater inhabitants, For example, "karp, zander, other fishes including turtles and mollusks", but in many cases English speakers mean "fin fish" when they say "fish"
So, in which cases "fish" means "fin fish" and in which cases "fish" means "underwater inhabitants"
