According to the terms of the game Catch Fish, you start your way in business as an ordinary fisherman. Stock up on a fishing rod and go to the pond to catch a couple of fish for lunch. As soon as you have more prey than you need for food, you can sell it at special outlets. You have to manage your own markups to secure a suitable profit. It’s easy enough to play. At your disposal is a whole island with shops and special aquariums, where you can no longer catch, but breed fish.
