Fish (or other aquatic creatures)
Freshwater fish are the most common aquatic animal raised using aquaponics due to their ability to tolerate crowding. Freshwater crayfish and prawns are also sometimes used, as they excrete nutrient rich feces. There is a branch of aquaponics using saltwater fish, called saltwater aquaponics. There are many species of warmwater and cold-water fish that adapt well to aquaculture systems.
In practice, tilapia are the most popular fish for home and commercial projects that are intended to raise edible fish because it is a warmwater fish species that can tolerate crowding and changing water conditions. Barramundi, silver perch, eel-tailed catfish or tandanus catfish, jade perch and Murray cod are also used. For temperate climates when there isn't ability or desire to maintain water temperature, bluegill and catfish are suitable fish species for home systems.
Koi and goldfish may also be used, if the fish in the system need not be edible.
Other suitable fish include channel catfish, rainbow trout, perch, common carp, Arctic char, largemouth bass and striped bass.
