Before farming sturgeon should be well prepared, because sturgeon is a warm water fish, so it has certain requirements in all aspects, the area of the farm site can not be less than 5 acres. When 15 days before the release of fry, let the pond into the water about 20cm, and splash the whole pond with quicklime to water. When stocking the fry, you should choose the sturgeon fry without disease and health, and keep the breeding density at 500 tails/mu.
First, how to raise sturgeon
1, in the breeding of sturgeon before there must be adequate preparation, because the sturgeon is a kind of warm-water fish, so it has requirements in all aspects. The area of the breeding site must not be less than 5 acres, generally 6-9 acres is appropriate. Pool water must be deep, and the water quality should be clean and pollution-free, the transportation near the farm should be convenient, and there should be a special feed table in the farm, and at the same time, we should also prepare the oxygen booster or oxygen supply equipment.
2, in the first 15 days before the release of seedlings, you can add the pond water to 20cm or so, and then use quicklime to water for the whole pond sprinkler, the pond disinfection, eliminating toxic substances in the water, the pond can be discharged after about 3 days of soaking pond water. You can also use tea seed cake for pond disinfection, before disinfecting the tea seed cake broken up and soaked in water for 24 hours, for the whole pond sprinkling, so that not only can kill the fish and shrimp in the pond, the rest of the tea bran can also be used for fertilizer.
3, stocking of fish fry must be selected without disease, healthy sturgeon fry, breeding density is generally 500 tails / mu. Stocking must consider whether the water temperature is appropriate, but also consider the time of the sturgeon adult market, if the fry need to be transported, about 2 days before the transportation must stop feeding the fry.
4, the sturgeon is a relatively mild carnivorous fish, mainly to aquatic insects, benthic animals, small fish and shrimp for food, the juvenile fish mainly to zooplankton, benthic animals, aquatic insects and their larvae for food. In the artificial rearing environment, domesticated sturgeon fry and adult fish can ingest artificial feed, feed crude protein content of 40-45%, particle size between 0.6-1 mm, daily baiting rate of 6-8%.
Second, the sturgeon is a sea fish or freshwater fish
1, the sturgeon is more species, living in freshwater is a freshwater fish, living in sea water is a sea fish. Sturgeon is one of the earliest existing origin of vertebrates, belonging to the bony fish class, spoke fins subclass, cartilaginous sclerotinia general order, sturgeon-shaped order.
2, the breeding of sturgeon if the use of feed feeding, you can choose to artificially cooperate with the granular material, granular material, the main raw materials are fish meal, yeast, blood meal, wheat, corn, silkworm pupae and so on. The stability of pellets in water is relatively high and can be maintained for more than half an hour. Fish species should stop baiting for 2-3 days after entering the box, so that the fish species can adapt to the environment, and can start baiting after 2-3 days.
3, the daily management of sturgeon should be arranged to guard, morning, noon and night must be checked. An hour after each feeding of fish to check the feeding situation, adjust the amount of bait, if you find a floating dead fish should be fished out in a timely manner. Every 10 days or so to clean the pond, remove the pond above the debris and algae, to ensure that the pond inside and outside the water exchange smooth.
