The Complete Guide Catfish

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

1. Preparation Pond Catfish
There are various types of pools that can be used for a catfish . Each pool type has advantages and disadvantages of each when viewed in terms of cultivation . To decide what the appropriate pool , please consider the environmental conditions , the availability of manpower and funding sources exist .
Types of pools that are commonly used in catfish farming is ground pools , pool cement pool tarp , floating nets and cages . However, in this article we will discuss ground pool , considering the type of pool is the most widely used by fish farmers . For additional knowledge , please read how to make a fish pond . Steps that must be done in preparing the ground pools are as follows :


a. Drying and Tillage

Before the seeds sown catfish, the pool must be dried first. Drying time ranges from 3-7 days or depend on the hot sun. As a rule, when the ground was cracked, the pool can be considered to be quite dry. Drying ponds aims to break the presence of microorganisms that cause germs. Microorganisms can bekembang of catfish farming previous period. By draining and drying, most of pathogenic microorganisms will die.
Once drained, plowed soil surface or reversed with a hoe. 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 contained in the bottom of the pool. The sludge is usually stink 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 by fish.

            b. Liming and Fertilization

Liming serves to balance the acidity of the pond and help eradicate pathogenic microorganisms. Type of lime used is dolomite or lime.Liming is done by stocked evenly on the surface of the pond. Once dotted with limestone, turning the soil in order to chalk seep inside. The dose required for calcification is 250-750 grams per square meter, or depending on the degree of acidity of the soil. The more acidic the soil the more lime is needed. The next step is fertilization. Use organic fertilizer blend plus urea and TSP. Type of organic fertilizer is recommended manure or compost. The dose 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.


        c.Water Management Pond

The ideal water level 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 pool and allows 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, water pools plus a regular basis according to the growth of catfish to the ideal height.
