the pool must be drained telebih first

Catfish is one of the types of fish that can live in a high density. This fish has a conversion rate of feed into body weight is good. By this nature, catfish farming will be very profitable if done intensively. There are two segments of catfish farming, namely segments and segments hatchery rearing. Segment hatcheries to produce seed betjuan catfish, while the enlarged segment aims to produce catfish ready for consumption. On this occasion alamtani will discuss the preparation stages of rearing catfish farming segment.

Preparation of a catfish pond


There are various types of pools that can be used for catfish farming. Each type has advantages and disadvantages to an individual when viewed in terms of cultivation. To decide what is the appropriate pool, please consider environmental conditions, availability of labor and resources there. These types of pools are commonly used in catfish farming is ground pools, pool cement pool tarp, and a floating net cages. However, in this article we will discuss ground pool, considering the type of pond is the most widely used by fish farmers. As additional knowledge, please read how to make a fish pond. Stages to be done in preparing the ground pools are as follows:


Before catfish seed sown, the pool must be drained telebih first. Pegeringan long range 3-7 days or depends on the heat of the sun. As a rule, when the ground was cracked, the pool can be considered dry enough. Draining the pool aiming to break the existence of microorganisms that cause seedling diseases. Microorganisms can bekembang of catfish farming earlier period. By draining and drying, most of the pathogenic microorganisms will die.


After drying, the surface of the plowed soil with a hoe or reversed. Tillage is needed to improve soil friability and dispose of toxic gases that accumulate in the soil. Along with the process of piracy, lifting a layer of black mud found at the bottom of the pond. The mud is usually stinks because storing toxic gases such as ammonia and hydrogen sulfide. The gases that are formed from a pile of leftover food that is not eaten fish.


Liming serves to balance the acidity of the pond and help eradicate pathogenic microorganisms. Type used is dolomite lime or quicklime. Liming is done by stocked evenly on the surface of the pond. Once dotted with lime, lime the soil to seep through to the inside. The dose required for liming is 250-750 grams per square meter, or depending on the degree of soil acidity. The more acidic the soil the more lime is needed.


The next step is fertilization. Use a blend of organic fertilizer plus urea and TSP. Types of organic fertilizer is recommended manure or compost. The dose is as much as 250-500 grams per square meter. While chemical fertilizers are urea and TSP each 15 grams and 10 grams per square meter. Fertilizing the pond aims to provide nutrients for aquatic biota such as phytoplankton and worms. Biota is useful for natural food catfish.


The water level is ideal for catfish farming is 100-120 cm. Filling the pool is done in stages. Once fertilized pond, fill it with water to the extent of 30-40 cm. Let the pool exposed to sunlight for one week. With such depth, sunlight can still penetrate to the base of the pond and allow the bottom of the pond biota such as phytoplankton grow well. Water pond was overgrown with greenish phytoplankton. After one week, the seeds are ready stocked catfish. Furthermore, the pool water added periodically in accordance with the growth of channel catfish to the ideal altitude.
