Hi steemit, meet again with me 
Cultivation Catfish is an agribusiness cultivation that needs serious attention. In addition to the market demand for catfish is very high, both national consumption and exports, catfish farming can also be done on a narrow land.
Separation - Cultivation of Catfish
The spread of catfish seeds in this phase is very vulnerable to death, mainly due to stress or injury during capture or transport. Solid dispersion between 500-750 heads / m2. So for the pond cultivation area of 10 m2 can be stocked seeds as many as 5000-7000 tail. The spread of catfish seedlings must be done very carefully, following the way of spreading catfish seedlings to reduce the risk of stress and injury.
Transfer of seedlings done in the morning or late afternoon at the time the water temperature is not too high. Catfish seedling picking using a mesh-sized meeting and soft.Bibit catfish placed using a container that has been filled with water from larva spreading pond.Setelah container full enough, transferred to the pond stock very carefully.
The container is put into a nursery pool until the pond water enters the container. In this way the catfish seedlings will swim out of the container
by itself.
WATER ARRANGEMENT - CULTIVATION OF LENDER SLEEPING
The water quality of the nursery pool needs to be maintained, the most effective way is the continuous use of flowing water of the paralon system with the water debit not too large.
In the cultivation of catfish nursery, water quality should not decrease too fast. This is because the size of the fish is still very small, so the dirt caused not so much. Additional feeds are given in small amounts, in the form of flour to support the growth of fish, so as not to cause the residual sediment feed that can reduce water quality.
ADDITIONAL FEEDING - CULTIVATION LELE SENDING
Catfish seed size 1-3 cm can not eat pellets in the form of granules. In the first week there is no need for additional feed. The catfish seedlings will feed on natural food available in ponds, such as plankton, water flea (Daphnia sp.) Or silk worms (Tubifex sp.) To that end, it is endeavored that the pond contains many natural feeds, for example by fermented manure. In the second to third week should be given additional feed in the form of flour. Feed is given three times, ie morning, late afternoon and evening. Feeding done little by little, until there are no more catfish seeds that chase the feed.
CONTROL OF HAMA AND DISEASES - CULTIVATION OF LENDER SLEEPING
Pests on the cultivation of catfish seedlings include, snakes, birds, lizards, and frogs. So we have to prevent these pests from entering the pond. Prevention can be done using woven bamboo to cover the surface of the pond. In addition, sanitation should also be done in the pool area, so that the can be pressed. When the pest has already entered, should be removed from the pond.
Prevention of disease can be done by maintaining water cleanliness and water pH settings. Keep the water pH always around 6.5-6,8. If the pH of the water is too low, you can add enough lime to the farm. Water pH measurements may use litmus paper or pH tester.
If the catfish seedlings show signs of disease, especially fungi, can be given Malachite Green Oxalite 1-5 ml or Methylene Blue 10 ml per 1 cubic meter of water.
Selection of Catfish Seedlings After 14 days the catfish seedlings show signs of disease, especially fungi, can be given Malachite Green Oxalite 1-5 ml or Methylene Blue 10 ml per 1 cubic meter of water so it has good growth.
The second selection is done when catfish seedlings have been maintained for 21 days. The quality of the seedlings is a little under the seeds of the result.
In nursery phase two is not much different from first stage nursery, only the density of the spreading should be reduced to 250-300 tail / m2.
MAGNIFYING IN THURSDAYS
Basically the method of cultivating catfish using tarpaulin pond is a solution for several conditions, among others, narrow land, small capital and solutions for water-scarce areas. Catfish is a fish that has some privileges and much in demand people.
Catfish cultivation is very easy. In addition to not requiring water in large quantities, catfish are also relatively resistant to disease. Water temperature regulation and adequate feeding are the keys to successful catfish farming. In addition to more easily maintained, catfish are also fast in its growth. With bad water conditions, catfish are able to survive and thrive, thus the solution of catfish in the tarpaulin pond becomes an alternative that needs to be tried. Cultivation of catfish tarpaulin pond system brings a promising business opportunity and does not require large business capital. Lele cultivation analysis can be done in various models for consumption and breeding. Cultivation of catfish enlargement is an effort catfish cattle to the size of decent consumption. Usually from 1 ounce to 1 kg per head.
MAINTENANCE OF FISH LELE - CULTIVATION OF MAGNIFICENT LELE
At the age of seven days the water height is increased to 50 cm. There is a good idea provided a kind of protection for catfish. Because the catfish is a fish that likes to hide in a closed area.
Feeding is done three times a day, ie morning, afternoon, and evening. Feed is given little by little until there is no catfish that chase the feed. If in the environment available natural foods such as snails, shellfish, golden snail, termites etc., can be given such natural food. Natural foods in addition to saving expenditure also has a high protein content so that the growth of catfish faster.
Replacement of water is done once a week, approximately 10-30% of the volume of pond water, so that the pool is not too dirty and to reduce the disease. Disease in catfish easily attack on water in dirty condition. At the age of one month conducted catfish selection. Usually catfish experience growth that is not the same, so if not separated the catfish with a small size will not compete in fighting for food. In addition, separate if there are fish that indicated the disease so that the disease is not contagious.
HARVEST FISH LELE
At the age of two months, catfish is ready for consumption or if it wants a larger size, catfish culture can be done for 3-4 months.
