Most catfish production occurs in earthen ponds, typically 5 to 10 acres in size, with relatively small numbers produced in cages and raceways. A new production system developed at Mississippi State University, the split-pond system, has been shown to improve yields, and farmers are beginning to add these systems to their farms.
Most catfish are raised in multiple-batch production. Small catfish fingerlings are typically stocked each spring and market-sized fish removed periodically by seining.
Ponds are left for production for years without draining, as wastes are removed through natural processes within the ponds. In single-batch production, fingerling catfish are stocked and grown until almost all of the fish have reached market size, then the entire pond of fish is harvested at once, and then the pond is re-stocked. In catfish feed production, the ground feed ingredients are mixed and sent through an extruder, resulting in feed pellets that float.
To feed fish, farmers use a truck or trailer-mounted hopper with a blower that shoots the feed pellets over the water surface. Fish farming handbook. Download fish-farming-handbook.

Conference paper. Aquaculture practised in Thailand is in the form of pond culture and cage culture in freshwater, brackishwater and coastal areas. The main species cultured include freshwater prawns, brackishwater shrimp, cockles, mussels, and various freshwater and marine finfishes.
There is good potential for increased production from freshwater, brackishwater and marine aquaculture. It will be several years before aquaculture production will contribute substantially to total production. Nonetheless, the culture of high value species of shrimp and fish could contribute significantly to export earnings during the next 5 to 10 years.
Conducted primarily by government agencies, research and development are along the lines of increasing seed supply, establishing new culture techniques or improving older ones. The Department of Fisheries DOF together with some private companies have ventured into the development and testing of artificial diets for the various cultured species using a variety of indigenous feed stuffs. Major increases would come from bivalve mariculture mt , brackishwater ponds 36 mt freshwater ponds 46 mt and brackishwater cage culture 20 mt.
At an annual per capita consumption of 32 kg some mt of fish is required for the projected of Coastal marine capture fisheries, the mainstay of Malaysia's fishsupply, has not shown any increase in landings over the last few years.
In fact in there was a decline of 3. This declining contribution of marine fisheries is compensated by an increase in aquaculture production. In , aquaculture contributed 51 mt to the total fish supply. Malaysia does not have a long standing aquaculture tradition unlike its neighbours in the Indo-Pacific.
Even then, the industry has seen rapid growth in the last few years. Today there are 19 species of finfishes, crustaceans and shellfish cultured in the country. The main freshwater fish species bred and cultured are bighead carp Aristichthys nobilis , grass carp Ctenopharyngodon idella , common carp Cyprinus carpio , Indonesian carp Punctius gonionotus , catfish Clarias macrocephalus and Pangasius spp , snakefish gourami Trichogaster pectoralis and tilapia mainly Oreochromis niloticus.
Marine finfishes bred and cultured are sea bass Lates calcarifer , grouper Epinephelus sp. Penaeus monodon is the dominant marine prawn species bred and cultured but culture of P.
Macrobrachium rosenbergii is the only freshwater prawn cultured commercially.
