Who does not know fish cork? Fish are often the prey of fish farmers because predators are troubling one, is now increasingly prevalent cork harvested for meat fish has its own delights are not the same as other fish. Catfish are sought after by buyers due to the dense texture of the meat.
fish Cork
Aquaculture way good-Turns Cork cork fish is a fish native to Indonesia. Live in the waters around us, in the swamp, in reservoirs and rivers where the water is calm. But catfish that can be bought in the markets and stalls, most likely from Borneo. Because of the island that is now the largest supplier to markets throughout Indonesia. But unfortunately, the fish populations in natural cork has begun to diminish, so budiadaya this fish needs to be developed.
Before entering the cultivation way it is good we know about biology, especially habitat, living habits, eating habits and sistematikanya. In Kalimantan, catfish are found in inland swamps, live at the base of the shallow waters, is carnivor or meat eaters, especially small fish that approached him. Cork fishing is seasonal, spawn in the rainy season.
By systematics, a fisheries expert, Kottelat (1993) insert into: Class: Pisces; Order: Labyrinthycy; Family: Chanidae; Genus: Channa; Species: Channa striata; synonymous with Ophiochephalus striatus. Catfish has another name, namely cork proceed Indonesia, Kalimantan Haruan a name. While the language is called Snaka Inggeri Fish Head.

Different male and female
Male and female catfish can be distinguished easily. You do this by looking at the signs on the body. Males characterized by an oval head, darker body color, sex milking pit and when massaged clear white discharge. Females characterized by rounded heads, lighter body color, enlarged and flabby stomach, when sorted out eggs. Male parent and had already reached 1 kg.
Spawning
Spawning is done in a concrete or fiberglass tubs. How, to prepare a concrete tank size of 5 m long, 3 m wide and 1 m high; dried for 3-4 days; feedback as high as 50 cm of water and let it drain for spawning; as a spawning stimulus, inputs to water hyacinth cover most of the surface of the tub; input input 30 breeding females; feedback also 30 breeding males; let spawn; take eggs with finely sekupnet; eggs ready for hatching.
To determine the spawning is done every day control. Egg is floating on the water surface. One breeding female can produce as many eggs 10000-11000 grains.

hatching eggs
Hatching eggs done in aquaria. How: prepare an aquarium length 60 cm, width 40 cm and height 40 cm; dried for 2 days; clean water contents as high as 40 cm; pairs of two aeration points and turn during hatching; pairs well water heater temperature up to 28 OC; input eggs at a density of 4-6 butir/cm2; let it hatch. The eggs will hatch within 24 hours. Until two days, the larvae do not need to be fed, because they store food reserves.
larval rearing
Maintenance done after 2 days the larvae hatch until the age of 15 days, in the same aquarium with density 5 tail / liter. Excess larvae can be kept in another aquarium. At the age of 2 days, larvae fed with Artemia naupli frequency of 3 times a day. From the age of 5 days, the larvae were fed an additional form of daphnia 3 times a day, to taste. To maintain the quality of water, do penyiponan, by removing dirt and leftover feed and replace with new water as much as 50 percent. Penyiponan done 3 days, depending on water quality.
separating
Catfish nursery I performed in ground pool. The trick: to prepare the pool size of 200 m2; dried for 4-5 days, fix all parts; String together kemalir with a width of 40 cm and height 10 cm; averaged essentially ground; scatter 5-7 sacks of chicken manure or quail; contents as high as 40 cm of water and soak for 5 days (no water flow); stocking 4,000 larvae in the morning, after 2 days, give 1-2 kg of flour pellets or pellets that have been soaked every day; crop seeds after 3 weeks of age.
