cultivation of catfish



Business opportunities catfish farming is one business opportunity that is taken into account at this time. If we look at many of the seller of the food supply is needed catfish catfish every day, it is this which makes the demand of fish has become increasingly high on the market and open up potential business opportunity that is promising. Livestock Catfish relatively easy when compared with other freshwater fish such as carp or tilapia because it is more resistant to disease and environmental conditions. The following is a general overview on how to catfish farming

* Catfish Hatchery.

Catfish farming is to produce seed to a certain size by mating male and female parent in special spawning ponds. Catfish hatchery has a good prospect with a high consumption of catfish and catfish enlargement of many businesses.

* Cultivation System

There are three seeding systems are known, namely:

1. Bulk System. Done by placing a male and female catfish in a pond with a certain ratio. In this system the male parent is invited free to seek a partner for mating in the nest spawning, so it depends on the activity of the male parent looking for a partner.

2. Pair the system. Performed by placing the male and female in a special pool. Its success is determined by the accuracy of determining a suitable match between the two carriers.

3. Injection seeding system (Hyphofisasi).

Performed by stimulating the catfish to spawn or ovulation with injections of extracts of glands Hyphofise, located next to the bottom of the cerebrum. For this purpose there must be a fish as donors Hyphofise gland that also must be of the type of catfish.

* Stage Cultivation Process

A. Making Fitness.

There are two kinds of / pool type, ie tub and pool (pool excavation). The selection pool type should be tailored to the available land. Technically, both on the type of tub or type of excavation, seeding catfish must have:

Pond reservoir. Get direct input from outside water / water resources. Function for the deposition of mud, water supply, and the growth of plankton. Reservoir pond is a source of water for the pond to another.

Parent pool maintenance. Male parent and bertina during egg maturation pond reared on its own as well as the maturation of the egg and sperm cells.

Spawning pool. The place of marriage of male and female parent. In this pool should be available spawning nests of roofed, brick, bamboo and others as a male parent and female relationships.

Separating pool. Serves to raise chicks that have hatched and been 3-4 days old. Displacement done at that age because chicks began requiring food, which previously were using egg yolk reserves the parent in the digestive tract.

B. Parent Selection

Male parent had a sign:

- Bone shaped flat head

- A darker color

- Movement more agile

- Slim stomach does not look bigger than the back

- Pointy shaped genitals.

Female parent is marked:

- Bone head convex

- Body color brighter

- Slow motion

- Stomach expands more than the back of the genitals is round.

C. Land preparation.

The processing of land (on the ground ponds) include:

- Drying. To clean the pond and kill various germs.

- Liming. Performed with Dolomite lime or zeolite doses of 60 gr/m2 to restore soil acidity and deadly germs are not killed by drying.

- Treatment TON (Nusantara Organic Farms). to neutralize various toxic and hazardous gases of decomposition of organic material remaining previously cultured with a dose of 5 bottles TON / ha or 25 grams (2 tablespoons) / 100m2. The addition of manure can also be done to increase the fertility of the land.

- Revenue Water. Done in stages, initially as high as 30 cm and left for 3-4 days to grow plankton as natural feed catfish.

In type A bath pool, pond preparation that can be done is:

- Cleaning the tub of dirt / residue before seeding.

- Drying the tub to dry and dead germs. Importation of water full and immediate direct fapat treated with the same dose TON

D. Spawning.

Spawning is the process of meeting a male and a female parent to remove the egg and sperm cells. Sign ready mating the male parent is colored red genitals. Female parent sign a yellow egg (if immature green). The fertilized egg attaches to the nest and within 24 hours will hatch into chicks catfish.

E. Displacement.

How to transfer:

- Reduce the water in the nests of spawning until the water 10-20 cm high.

- Prepare a shelter with a bowl or bucket filled with water in the nest.

- Match the temperature at both pools

- Remove the seeds from the nest to the container holding the cup or plate.

- Remove the seeds from the reservoir into the nursery pond with caution at night, because it is still vulnerable to high water temperatures.

F. Nursery.

Is enlarged up to size ready to sell, ie 5-7 cm, 7-9 cm and 9-12 cm with a different price. Nursery pond surface is given in the form of water hyacinth or protective cover of plastic to avoid the rising water temperatures that cause stress catfish easily. Feeding started in puppies catfish nursery ponds was transferred to this.

* Feed Management

Feeding catfish seedlings in the form:

- Natural food form of plankton, larvae, small worms and water fleas (best) is consumed at age under 3-4 days.

- Feed-made for age over 3-4 days. Have high nutrient content, especially protein content.

- To add a feed nutrients, each provision of artificial feed is mixed with the NASA POC with a dose of 1-2 cc / kg of feed (mixed with water to taste), to enhance the growth and endurance because it contains many elements essential minerals, protein and vitamins in optimum amounts.

* Water Management

The size of the water quality can be assessed physically:

- Water should be clean

- Bright green

- Brightness / transparency medium (30-40 cm).

The size of the chemical quality of water:

- Free of toxic compounds such as ammonia

- Have optimal temperature (22-26 0C).

To maintain water quality that is always in optimal condition, providing a TON of fertilizer is needed. TON containing elements essential minerals, fats, proteins, carbohydrates and humic acids are able to nurture and nourish natural food in the form of plankton and worm-type worms, neutralize toxic compounds and create a balanced ecosystem pond. TON treatment performed at the time of the land by way of dissolved and pour on the soil surface in the pool and at the new water intake, or at least every 10 days. Dosage is 25 g/100m2 TON.

* Health Management

Basically lelePada fish, puppies raised catfish will not hurt if you have a high endurance. Tillers catfish get sick more often caused by environmental conditions (water) is bad. Very bad water conditions encourage the growth of various germs either in the form of protozoa, fungi, bacteria and others. So in catfish hatcheries health management, which is more important is the maintenance of water conditions and high nutrition. In both of that, the role of TON and very large NASA POC. However, if the puppy already catfish disease, it is recommended to perform appropriate treatment. Diseases caused by infection with protozoa, bacteria and fungi can be treated with formalin, a solution of PK (Potassium Permanganate) or table salt. The use of these drugs must be carefully and the dose used must also comply.
