Mutant Fish Tycoon

Bad water. Good money. Start with one tank on a rundown dock. Grab fish from the conveyor, sell the catch and turn your patch of concrete into a mutant-fish factory. Keep the freaks. Sell the rest. Discover rare specimens, research mutations and automate the heavy lifting. Build upstairs, fill your rooftop and work towards your own offshore dock. Trade with the harbour locals, finish contracts and prestige for permanent bonuses. Your plot. Your collection. Your progress.
