Sturgeon Fry Breeding

First, fry holding and cultivation

The fry is raised and needs to be raised in the hatchery (cylinder) for 4 to 5 days. The rotifers can be fed after 2 to 3 days after the fish is released from the membrane. In this case, the rotifers should be fed with 180-200 mesh sieves in a timely manner. The feeding density can reach 10-15/ml, which is equivalent to 1 to 2 drops of water. One.

After the cubs are raised, the raised fry can be cultured for about 20 days, and they can grow into 2 to 2.5 cm in length. The Wuzi Cultivating Pool generally adopts a cement pool, and requires a smooth bottom, inlet and outlet, and a water outlet with a 40-60 mesh screen. After the raised fish siphons are sucked into the dense-eye sieve cages, the seedlings are counted and counted, and the debris is removed. 10,000 to 20,000 tails are released per cubic meter of water. Each day, they were fed one live feed each morning and evening and were fed with rotifers in the early stage. In the middle and late stages, larvae and copepods were fed, and the fish were baited with 100-120 mesh sieves. The feeding density was appropriately reduced. In daily management, shade shelters or concealed objects should be provided to keep the micro-flowing water or micro-inflating to ensure the dissolved oxygen is not lower than 4 mg/ml, change the water 25% to 30% every day, keep the water temperature no higher than 30°C, and the bait should pass clear water Feed after rinsing.

Second, fish breeding

The area of ​​the pond area is 2000~3000 square meters, with a water depth of about 1.8 meters, less silt, and convenient water and electricity. The pond is cleaned, water injected, fertilized and cultivated for food organisms 1 week prior to planting, and water and grass are set around the pond. Mesh, straw and other hidden objects. After the food organisms in the pool water reach a peak and the water quality is stable, they can be planted, and the fish fry can be placed in the hidden place. The main breeding place is about 20,000 larvae per acre, and about 2000 rearing fish are stocked with carp; Raising stocks of 0,800 to 10,000 larvae per acre, polyculture squid, head lice, squid, etc., can also be used with a small amount of stocking squid. Polyculture and collocation varieties should be released after the successful domestication of yellow snapper.

After 2 to 3 days of acclimation and feeding of the fish seedlings in the lower pond, a small amount of feed can be fed within 5 to 6 meters on both sides of the feeding table, 2 or 3 times a day, giving a fixed sound, gradually reducing the feeding range, and finally fixing to the material table. Feeding, domestication can be successful in about 10 days. There are two kinds of commonly used feeds: one is animal feed (frozen sea fish, poultry and other internal organs, etc.), and the appropriate blend of flour, bran, multi-dimensional additives through the hinge of the hinged machine into a soft pellet feed; second is the finished particle Feed, change the particle size and protein content with the size of the fish, generally used in the early, intermediate crushing material, protein content of 40% to 45%, particle size of about 1.5 mm in the later granular material, protein content of 35% to 40%, seedlings Seasonal feeding 3 to 4 times a day. Stingrays like to feed in the evening and at night. They must feed more properly, especially when they are fed by a feeding machine. Each feeding time should be no less than 20 minutes, with 80% to 90% of the fish to eat away.

Daily management of cultured stingrays, ponds must maintain fresh water, maintaining a transparency of more than 40 cm. It is necessary to add new water frequently, preferably well water; properly match with carp seedlings; no fertilization during cultivation; no over-feeding; noon feeding at night, proper activation of aerators; The water temperature does not exceed 30°C. Stick to the patrol pond and find problems in a timely manner.
