What Kind of Fish?

Water Temperature is the Key The most commonly grown fish in aquaponics systems are Tilapia. However, you do not have to eat the fish you grow. Many people use Goldfish, Koi or other species. The photo on the left is of a Tilapia that jumped out of its 300 gallon Rubbermaid tank last month. It is just barely big enough to be considered harvest ready. Tilapia are normally harvested at 1-1/2 to 2 pounds. (The water level of the tank was lowered to prevent this in the future as the tank contains many plants and would be difficult to cover with a net.) Tilapia are warm-water fish. They like 80 - 90 degree (F) water, but generally begin to die as the water temperature drops below 50 - 60 degrees (F) depending on variety. Tilapia are easy to grow, eat a wide variety of foods and are considered very hardy and disease resistant.   Other types of fish used in aquaponics systems include Bluegill, Channel Catfish, Largemouth Bass, Crappie, Pacu and various ornamental fish such as Angelfish, Guppies, Tetras and Mollies in warm water and Lake Perch and Rainbow Trout, among others, that live in areas that have colder water.
