1 Tilapia

Tilapia have been cultured commercially in the United States. They are hardy, grow rapidly, and are acceptable, though not well known to consumers. Tilapia are tropical fish and require warm water to survive. If water temperatures fall below approximately 50- 55° F, they will die. In this region, most Tilapia culture has occurred in ponds during summer or in heated units such as recirculating systems.

2 Golden shiners

Golden shiners are the mainstay of the live-bait industry in Arkansas, although some are cultured commercially in the Northeast. Usually cultured in ponds, golden shiners are less hardy than the fathead minnow. They require two growing seasons in order to reproduce. However, the golden shiner is more appealing to the angler and attains a larger size than the fathead minnow.

3 White suckers

White suckers are captured during their spring spawning run by some bait producers. Eggs are striped and incubated; hatched fry are reared in ponds. Suckers grow faster than golden shiners and in one growing season attain a size desired by bass and pike anglers. Market size and culture details require further research.

4Bullhead

Bullhead is a popular recreational and food fish in the Great Lakes basin. Experimental work indicates that black bullhead survives and grows well in ponds or cages. They do best in turbid waters.

Carp

Carp, an important finfish in the world, has minimal but growing demand in the United States. Technology to culture carp in ponds is well known and the fish is suited to conditions throughout the United States. The principal obstacle is poor consumer acceptance. Carp could provide a dependable supply of fish for use in value-added products such as surimi and fish sausage.

6 Grass carp or White amur

White amur is occasionally stocked in ponds to controlaquatic vegetation. The sterile triploid is most commonlyused. The fish survives well and grows rapidly.
