Sturgeon is one of the oldest fish on the earth, with a long life history and special form. There are eight kinds of wild sturgeon living in China, among which Chinese sturgeon and Siberian sturgeon are often heard. However, the Chinese sturgeon is a national protected animal and cannot be caught. At present, some edible sturgeons are artificially cultured, mostly Russian sturgeon, European sturgeon and other sturgeons imported from abroad. The culture of sturgeon will be different from that of other fish.

1, farm construction

For sturgeon breeding, it is best to breed sturgeon in the pond, because the fish will grow bigger. If there is no pond, a cement pond will be built to breed sturgeon. Generally a pond is about 4 meters long, 3 meters wide and 2 meters deep. The number of sturgeons in the pond can be determined according to the size of sturgeons. There should be clean water sources nearby for aquaculture, preferably running water aquaculture or running water aquaculture. The place where fry are cultivated should be built separately. Generally, it can be used as a greenhouse to raise seedlings in large plastic containers. Young fry look similar to other fish. Prepare some separate equipment.

2. Breeding preparation

Before stocking, clean the cement pool, sprinkle with lime solution and soak it for about a week, then clean it and soak it in clear water for a few days. Release before breeding, and then re-irrigate to the water depth of about1.5m. The seedlings will not be put into the pool until they are cultivated to a certain size. Feed should be prepared before stocking, oxygen aerator should be prepared, and oxygen should be supplemented in deep water. Inlets and outlets should be covered with nets to filter water.

3, fried stockings

Before stocking, fry should be disinfected, for example, they should be soaked in salt water or lime water for a few minutes at first, and then cleaned after thorough disinfection before stocking. Stock healthy fry. The water depth of stock fry is about 30 cm. Pay attention to warm water culture. Fish soaked in salt water can easily adapt to the temperature of the pool water. Stocked fry should be the same size. Balanced growth. Put a few before entering the pool to see if the water temperature is suitable, and then put them all in.

Breeding in the right place

Step 4 feed

Sturgeon is a carnivorous fish, which mainly feeds on underwater creatures, fish and shrimp. If it is cultured in cement ponds, there are generally no aquatic animals. Drop it by yourself, unlike a pond. Fish, shrimp, insect larvae and feed worms can be put in, and maggots and earthworms can be fed. It can also be fed with artificially prepared feed. Bone meal, fish meal and other healthy feed. The food you feed should be clean and disinfected.

5, management tasks

Feed, disinfect and salvage food residues regularly every day. When the water quality is not clean, change the water quickly and disinfect it regularly. The culture depth should be about one and a half meters. If there is no oxygen in the water, the fish will float and flutter, and an aerator will be used to increase oxygen. Patrol every day. Observe activities and environment.

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