Culture techniques of Sturgeon

Sturgeon is a kind of fish with a long history, special shape and the oldest on the earth. There are eight kinds of wild Sturgeon living in China, including Chinese Sturgeon and Siberian Sturgeon. However, the Chinese Sturgeon is a state-protected animal and cannot be fished. Now some edible Sturgeon are farmed, mostly Russian Sturgeon, European Sturgeon and other Sturgeon imported from foreign countries. How to cultivate Sturgeon will be different from other fish culture methods.

1. Construction of breeding farms

Culture Sturgeon, because the fish size is relatively large, so it is best to have a pond culture, if there is no pond to build a cement pond to culture, generally a pond is about 4 meters long, 3 meters wide, more than 2 meters deep. The number of Sturgeon raised in the pond can be determined according to the size of the Sturgeon. There should be clean water sources nearby, aquaculture, preferably live water aquaculture, mobile water aquaculture. Where fish fry are cultivated, they should be built separately. Generally, they can be made into sheds and raised in large plastic containers. The small fish fry looks like other fish. Prepare some separate equipment.

2. Culture preparation

Before stocking, clean the cement pool, sprinkle lime solution, soak for about a week, then wash it clean, and then soak in clean water for a few days. Release it before breeding and re-irrigate it to a water depth of about 1.5 meters. The seedlings are not released into the pond until they are of a certain size. Feed and aerator should be prepared before stocking, and oxygen should be replenished in deep water. The inlet and outlet should be covered with gauze to filter the water source.

3. Fish fry restocking

Before stocking, fish fry should be disinfected, for example, soak in salt water or lime water for minutes at first, thoroughly sterilize, wash and release. Release healthy fish fry, the water depth of fish fry is about 30 cm, pay attention to warm water culture. The fish soaked in salt water can easily adapt to the temperature of the pond water. The fry should be the same size. The growth is balanced. Put a few pieces before going down the pool to see if the water temperature is suitable and then put it all.

4. Feeding

Sturgeon is carnivorous fish, mainly eat underwater organisms, fish and shrimp and so on, if the cement pond culture, there are generally no aquatic animals. Put it on your own, not like a pond. Can put small fish and shrimp, insect larvae, cultured feed worms, maggots, earthworms and so on can be fed. It can also be fed artificially. Bone meal, fish meal, and other healthy feed. The food fed should be clean and sterilized.

5. Management tasks

Feed, disinfect food and salvage food residue regularly every day. When the water quality is not clean, you should change the water quickly and disinfect it regularly. The depth of aquaculture water should be about 1.5 meters. If there is no oxygen in the water, fish floating head, flapping, use an aerator to increase oxygen. Patrol every day. Observe the activities and the environment.

There are many differences in the details of Sturgeon culture, but there are also similarities, and there are similarities in the breeding process, but changes have been made according to the characteristics of Sturgeon.
