There are two types of Fish Farms in use by Hunt Clubs and Game Farms. One is to provide "easy" fishing from the shore or a small boat, which is tailored towards children, to introduce them into the sport.  Species include Trout Panfish, Bass and Perch.  Another function of a Fish Farm could be to provide a renewable food source, such as the raising of Perch and/or Catfish for sale in bars and restaurants.
