In my OED under usage of fish it says, and I quote-

"The collective plural ´fish´ is now usual,but the older form ´fishes´ is still used,especially in technical writing,when referring to different kinds of fish (e.g. the freshwater fishes of Europe) , and in biblical allusions etc. (e.g. five loaves and two small fishes ) "
