Fish culture technology

Disinfection and sterilization of fish ponds (culture ponds), release of fish fry, feed feeding, water quality control, daily management and fishing market, etc., different fish culture density and feed feeding are different, which can be determined according to the habits of fish species.

At present, the common methods of fish culture are:

1. Fish culture in pond

Ponds are the most common way of raising fish in rural areas, especially in mountainous and hilly areas. A dam is usually built at the foot of the mountain or halfway up the hillside, and a small pond is built, so that it can not only raise fish, but also be used to irrigate downstream farmland during the dry season.

two。 Rice field fish culture

Rice field fish culture is more in the mountainous areas of Hunan, Guangxi, Guizhou and other areas, generally raising a species called rice flower fish. When using rice fields to raise fish, the ridges of rice fields should be raised, it is best to install a block at the drain, and then dig a few deep ditches in the rice fields to facilitate the activities of the fish. We should also check the amount of water in the paddy field regularly and replenish it in time when the amount of water is insufficient.

3. Fish culture in reservoirs or lakes

The vast water area of the reservoir, of course, is not extensive farming, but a small area surrounded by a net, so that the fish cannot escape, and the management is similar to that of fish farming in a pond. The particular thing to pay attention to is to check the firmness of the fence regularly, otherwise the fish will be raised in vain.

4. Fish culture in artesian water

Without any treatment, the water for fish culture can make use of the drop formed by the natural topography to make the water flow through the fish pond without power. This type of equipment is simple and economical, but it is limited by geographical conditions and affected by climate.

5. Open circulating aquaculture

Its main feature is that a natural water body is selected as a reservoir and purification tank, which needs power pumping into the running pool, the drainage of the running pool is still back to the original pool, and the fish culture system is always connected with the natural water of the external source, so it is called open. Because of the low technical requirements, simple equipment and easy construction, this method is mostly adopted in our country at present.

The majority of farmers before fish culture, it is best to understand the local market situation, master culture technology, so as to maximize the efficiency of culture.
