Catfish

The catfish may become the most popular water fish in America. Since 1975, its consumption has grown significantly. Catfish now ranks third in overall consumption, just behind cod and flounder.

Raising of catfish isn’t a matter of dumping feed into a pond .A great amount of time is spent on caring for the fish.

Pond-raised catfish are surface feeders, so a special floating grain mixture must be used. Pond water must be clean and aerated. The mixture of gases in the water must be regulated. So the catfish have no odour and have mild flavour.

Catfish are hatched indoors in special breeding ponds. The fish lay about 2000 eggs per pound of body weight. In five months the fish are ready for the outdoor ponds. Everything is carefully monitored – ammonia, oxygen, nitrate, level.

Catfish eat a mixture of soybeans, corn, wheat and fishmeal. The pellets float, so fish do not eat off the bottom. In one day catfish consume 5 % of their body weight.

Fish are harvested when they are about two years old . An 1800 ft. seine is placed into the pond. Undersize fish swim through the seine .A mechanical aerator keeps water fresh as the number of fish inside the net increases.
