Before the seeds were scattered in catfish rearing ponds, which take into account is about the readiness of the pond include:
a. Pond soil preparation (traditional)
Bottom processing of soil cultivation or piracy and flattening the bottom. Pool wall amplified by hitting hit her with a wooden block so hard and dense so that no leakage occurs. Pemopokan soil embankment to the pond (covering parts of the leaking pool).
For shelter fish (catfish seeds) as well as facilitate the harvesting of the trench created / kamalir and pools (like for harvesting).
Provide lime into the pond which aims to eradicate pests, diseases and improve soil quality. The recommended dose is 20-200 gram/m2, depending on the acidity of the pond. For ponds with low pH can be more lime, and vice versa if the soil is good enough, giving the chalk can be simply to eliminate the possibility of pest and disease found in ponds.
Fertilization with chicken manure, ranged between 500-700 gram/m2; urea 15 gram/m2; SP3 10 gram/m2; NH4N03 15 gram/m2.
At the door of income and expenses mounted water filter
Then performed water filling the pool.
Swimming allowed for ± 7 (seven) days, in order to provide opportunities growing natural food.
b. Preparation pool wall
Preparation pool wall similar to the soil pool. The difference, in the pool wall is not done the basic processing pool, repairing trenches and sink to harvest, because the trench and sink to harvest is usually made Permanent.
c. Spreading Seeds
Before the seeds were scattered should be used to disinfect seeds consecrated by soaking in a solution of KM5N04 (potassium permanganate) or 35-dose PK gram/m2 for 24 hours or formalin with dose 25 mg / l for 5-10 minutes.
Spreading the seeds should be done in the morning or late afternoon or at the time was not hot air. Before you cast into the pond, once diaklimatisasi seeds (treatment temperature adjustment) by entering the water little by little into the seed container carriers. Seeds that had teraklimatisasi would automatically come out of the bag (container) transport the seeds to a new environment of the pond. This means that the treatment is carried out above the water surface where the container (bag) seeds float in water. The number of seeds tail/m2 stocked 35-50 cm in size 5-8.
d. FEEDING
In addition to natural foods, to accelerate the growth of channel catfish need supplementary feeding of pellets. The amount of food given as much as 2-5% per day from the total weight of fish that were scattered over the pond. Feeding frequency is 3-4 times every day. While artificial food composition can be made from a mixture of fine bran with the fish rucah with 1:9 ratio or a mixture of fine bran, bran, corn, chopped snails with a 2:1:1:1 ratio of the mixture can be made form of pellets.
e. Harvesting
Sangkuriang catfish consumption will reach the size when raised for 130 days, with a weight between 200 to 250 grams per fish with a length of 15 to 20 cm. Harvesting is done by withdrawing the pool water. Catfish will gather in kamalir and pools, so easily caught by using a Waring or lambit. Another way of catching using bamboo pipes or pipe pipe / bamboo placed based ponds, pond water during reduced, channel catfish will be entered into the joints of bamboo / pipe, then the fish can easily be captured or removed. Catch catfish collected in a sieve container / happa mounted on the pond where the water continues to flow to resting before the fish are transported to market.
Carriage of catfish can be done by using Karamba, fishing pole or a plastic jerry cans extended surface holes and with a small amount of water.
Production Process rearing activities presented in Table 1.

Sangkuriang catfish farming activities at the level of farmers are often faced with the problem of sickness or death of fish. In rearing activity, many diseases caused by poor handling of environmental conditions. Organisms that normally attack predators including snakes and eels. Whereas pathogen organisms are often attacked Ichthiophthirius sp., Trichodina sp., Monogenea sp. and Dactylogyrus sp.
