Cultivation mode of sea bass fry

Sea bass, which is the main sea bass at present, is mainly distributed in the coastal areas of China, Japan and Korea. The main producing places of sea bass in China are in the East China Sea and the Yellow Sea, which are the main economic fish. At present, perch has been cultured for a long time, the main breeding seedlings are fresh water seedlings and sea water seedlings, how to cultivate the seedlings is the main content of our article.

I. Pool cultivation

Nursery ponds can be built on their own, there is no clear stipulation how, generally small ponds 5 to 50 cubic meters, large ponds 50 to 200 cubic meters. The depth of the pond is about 2.5 meters, and the water depth is generally 1.5 to 2 meters. It can trim ponds of various shapes. At present, most ponds are circular nursery ponds. Large ponds are suitable for large-scale cultivation, fast and large in quantity in a short time, but they cannot be managed. Xiaochi is easy to manage, but it is not convenient to operate.

2. Pond cultivation

Ponds can be built and cultivated, and ponds are easy to be managed centrally. Pond drainage and irrigation is more convenient, and do not need to change water one by one, the natural environment of the pond is better, there are some wild bait, can enrich feed, pond space is larger, fish fry are more dynamic. The water source is relatively clean and can flow and change water. It's just that it's a little troublesome if the disease is prevalent.

III. Cage cultivation

You can choose a variety of cages, but it is better to have cages 3 to 4 meters deep, preferably with a cover to prevent escape. Cages that can be set up in any water, including the deep sea. Cage cultivation is relatively close to the natural water environment, cultivation of seedlings is better, can enhance adaptability, resistance and so on. But if there is a high tide or something, you should pay attention.

IV. matters needing attention

Aquaculture ponds and ponds must be disinfected first. Generally, a large amount of quicklime dissolved water is sprinkled throughout the pond, leaving no dead corners. After soaking in the pond for a week, wash away the lime, and then release the fish fry after irrigation. All fish fry must be soaked in bleach disinfectant for 10 minutes before launching. We should also pay attention to the adaptation of the water temperature. The fish fry should first adapt to the water temperature of the pond and then go into the pond.

Sea bass is an important economic fish, there is still a period of seedling cultivation period before seedling culture, there are several cultivation methods determined by the environment, mainly in order to better cultivate sea bass, but also to cultivate more options. The cultivation method can be decided according to the need.
