Guide How Livestock Catfish
This time I would Distributing Benefit Guide How Cultivation Type Catfish let's look at the following article.

A. Location and media for catfish

Altitude location for catfish farming areas lowland to highland (about 700 m above sea level). While the ideal temperature for life catfish between 25-28 ° C. For larval growth between 26-30 ° C. In the spawning period between 24-28 ° C, and for the level of acidity (pH) water pools ranged from 6.5 to 9. The hardness (degrees granules kasac) optimal maximum of 100 ppm and 50 ppm. Turbidity water (turbidity) that will be caused by mud between 30-60 cm, to measure it can use a tool called sicchi disk.

     Then the levels of oxygen (O2) for adult catfish 0.3 ppm to saturate for seed / child catfish. CO2 content should be less than 12.8 mg / liter at a temperature of 25 ° C water and ammonium bound 147.29 to 157.56 mg / l.

Although catfish, including fish that can adapt to the environment of low water conditions, the quality of ugly, muddy, dirty and a little oxygen, but to maintain the quality of farmed catfish and maximum should pool water for maintenance should not be contaminated by hazardous waste.

B. Seeding catfish

In carrying out the cultivation, seeding stage is very important and should be well prepared.

1. Preparation of the parent catfish

The characteristics of the male parent and a female parent

Catfish male characteristics: smaller head size

     Chest skin color or darker than the base body female parent

     Urogenital papilla (sex) rather prominent (tapered) memenjang towards the rear. Located behind the anus and reddish

     Bone agile movements of short and somewhat flattened head / flat (depress) Stomach slimmer

If the abdomen in-stripping manually from the stomach to the direction of the tail, will come out thick white fluid (spermatozoa; seminal) The skin is more delicate than the female catfish parent.

Catfish female characteristics:

Larger head size chest skin color or basic body somewhat brighter urogenital papilla (sex) oval (rounded leaves), reddish, the hole is rather wide, and is located behind the anus movements were slow bone short and somewhat convex head Stomach bloated and soft If parts The belly-stripping manually from the abdomen towards the tail, will come out a yellowish liquid (ovum / egg), skin rougher than the male catfish

Parent catfish were chosen to be quite aged. Local catfish began mature at the age of 6-8 months. At this age, the local catfish body weight reached 100 g. For African catfish reach two or three times (200-300g). That is, in this age of the parent catfish are able to spawn. In addition, select a parent who has a body length of about 20-50 cm. For aquaculture, the parent should catfish comes from the cultivation that has been accustomed to life pond.

2. Preparation of the spawning pool

The base and walls of the pool should be made permanent. If not possible, spawning and maintenance can be performed catfish pond or pool walled land with the land base. The slope of the land base of the pool is made about 5-10 degrees.

Spawning pool consists of two main parts, namely the shallow (70%) and pools (30%). Part puddles created in the middle pool with a depth of 50-60 cm. This puddle serves as a refuge parent when venting pool.

In spawning catfish, on the sides of the pond should be prepared nest nesting. The inside of the tub needs to be equipped spawning nests in the form of a wooden box without basic size (25 x 40 x 30) cm as spawning nests.

The top of the nest box provided with holes and lid to see the eggs in the nest. Meanwhile, the front of the nest box a little dark. Nest also need to be roofed and gravel as the media puts egg hatching results.

Apart from the wooden box, spawning nests can also be made from coal pile, plastic buckets, or other former rod. Before use, nest boxes should be in a hygienic condition. Therefore, clean the nest by washing with water, then rinse with 40% formalin or KMnO4, then rinse with clean water and dry.

3. Spawning

Spawning can be done in two ways, namely natural spawning and artificial spawning (injection / hipofisasi).

In the process of natural spawning, there are two ways, namely, Breeding pairs and broadcast spawning, but I will inform logged to just spawning in pairs only.

Catfish spawn sepenjang years. Most spawning occurs simultaneously with the arrival of the rainy season, sepenjang rainy season to dry season transition. Throughout his life, the parent catfish aquaculture capable of spawning up to 15 times. Parent catfish are well maintained will spawn every 2-3 months and will continue to spawn up to 5 years old.

For 10 days, starting from the time the parent is inserted into the spawning pond, pond water level is entered only a puddle surface (30-60Cm). on days 10-20, the pool water is increased to 10-15 cm (up to close the spawning nests), and feeding is stopped.

Denagn this treatment, within 10 days following the parent will spawn and lay eggs in the nest available. Approximately 24 hours later, the eggs will hatch, the seed can remain in the care of the parent or separately maintained in an seedling (the pond).

Spawning pairs

Spawning in the pair is not much different from natural spawning. The difference lies only in the size of the spawning pond is needed. Tub or pool spawning in pairs can be made of concrete or terrazzo with a size of 1m x 1m or 1m x 2m. As a place to spawn, spawning nests pool should be equipped on the inside.

After spawning pond is ready, scatter a pair of parent in a tub filled with water up to about 25 cm. Water conditions should be flowing and stocking should be done at 14:00 to 16:00. Let the parent for 5-10 days and give feed intensively. Entering the 10 days, a pair of parent usually has spawn, lay eggs, and the eggs hatch within 24 hours. Eggs are good is bright yellow. Children catfish that have hatched and young (larvae) can be fed naturally beruapa water fleas or mosquitoes. Having increased in size. Children worms and catfish can be boiled egg yolk.

4. Hatching

Hatching eggs can be done in two ways, namely:

     Hatched pond seedling / nursery

     Left to hatch naturally nest found on the spawning pond.

Method 1

There are steps to be taken if the eggs are maintained in an seedling (the pond), namely: Immediately remove eggs once spawning is complete.

Maintain intensive eggs in the pond seedling (the pond).

Larval growth requires pool water temperature between 26-30 ° C.

Method 2

If allowed to be in the care of the parent, let the eggs hatch and the separation of parent seed to be gradual.

The stem and seed separation is done by the following steps. When the seeds a week old, immediately separate the mother from the pool and let the males stay in the pool keep her children.

After the age of 2 weeks, separate puppies from the male parent. Next, remove the catfish chicks from the nest and move to an seedling (nursery).

To collect seed, first venting the pool water to the extent puddle. Furthermore, seed flow through the discharge pipe and fry catfish that has been moved to the pond can be reared intensively.

C. Enlargement Seeds

After hatching, breeding seeds need extra attention and maintenance intensive. Extensive maintenance is expected to reduce the death rate of seed and make them grow to be more rapid.

feeding

     On days 1 to 3, catfish seed does not need to be fed extra because they have a yolk sac (yolk sac) were taken from the hatch.

Day 4 until the end of week 2, the seeds were given zooplankton, ie daphnia and Artemia containing protein 60%. The dose is 70% times the biomass each day. Two types of natural food is given four times a day. Feed stocked around a water intake (inlet).

Approximately 2-3 days before feeding zooolankton ends, catfish seed gradually introduced to the feed in the form of powder containing 50% protein. The powder feed may be a mixture of egg yolks, flour shrimp, as well as a bit of porridge nestum. To get used to the new feed, feed powder is given approximately 10-15 minutes before administration of zooplankton.

         The third week, flour feed given as much as 43% times the biomass each day.
         Fourth week, flour feed given as much as 32% times the biomass each day.
         Fifth week, feed flour dberikan 21% x biomass each day.
         Sixth week, the seeds were fed in the form of floating pellets.

Nursery and enlargement

Maintenance performed in an catfish seed seedling (nursery) with nursery through three stages, namely nursery 1, 2, 3.

the pond 1 is used for treating seed until its size reaches about 1-3 cm. density of the pond to the seeds of this size between 60-100 tail / .

Furthermore, seed size of 3 cm is maintained further on seedling pool 2 until he reached 21-30 days and the length is about 5-6 cm. The seeds of this size can be kept back in the pond seedling 3 or it could be sold as seed.

After maintained in seedling pool (the pond) 3 up to 35-45 days old stomping, body length catfish has reached 10-15 cm. The seeds of this size would be great if it is maintained in a rapid rearing ponds.

Although complicated manual way cattle and catfish farming is very short, but for those of you who want to start a cattle or catfish, the info guide above earlier may be added value for you and hopefully be useful information, but for those of you who want to get the info more information please read only See how other cultivation. semongaa this article very useful.
