Embodiment 1

[0024] A method for improving the quality of carp nursery, comprising the following steps:

[0025] (1) Select parent fish: select carp with good growth condition and well-proportioned body shape as parent fish, the age of said parent fish is 2 years, body weight is 1kg, and has typical species characteristics.

[0026] (2) Cultivate broodstock: put the broodstock selected in step (1) into the breeding tank for cultivation, and feed the broodstock special feed. Wherein, the water temperature of the cultivation pond is controlled at 8° C., and the dissolved oxygen in the water is controlled at 6 mg / L. On average, each broodstock is fed with 3% of its body weight by the weight of the special feed for broodstock every day. The special feed for broodstock is prepared from the following raw materials in parts by weight: 50 parts of soybean meal, 30 parts of bone meal, 20 parts of fish meal, 5 parts of silkworm chrysalis, 5 parts of choline chloride, 0.3 part of calcium dihydrogen ...

Embodiment 2

[0031] A method for improving the quality of carp nursery, comprising the following steps:

[0032] (1) Select parent fish: select carp with good growth condition and well-proportioned body shape as parent fish. The age of said parent fish is 3 years, body weight is 2kg, and has typical species characteristics.

[0033] (2) Cultivate broodstock: put the broodstock selected in step (1) into the breeding tank for cultivation, and feed the broodstock special feed. Wherein, the water temperature of the cultivation pond is controlled at 12° C., and the dissolved oxygen in the water is controlled at 15 mg / L. On average, each broodstock is fed with 5% of its body weight by the weight of the special feed for broodstock every day. The special feed for broodstock is made from the following raw materials in parts by weight: 60 parts of soybean meal, 40 parts of bone meal, 30 parts of fish meal, 10 parts of silkworm chrysalis, 10 parts of choline chloride, 0.5 part of calcium dihydrogen ...

Embodiment 3

[0038] A method for improving the quality of carp nursery, comprising the following steps:

[0039] (1) Select parent fish: select carp with good growth condition and well-proportioned body shape as parent fish. The age of said parent fish is 3 years, body weight is 2kg, and has typical species characteristics.

[0040] (2) Cultivate broodstock: put the broodstock selected in step (1) into the breeding tank for cultivation, and feed the broodstock special feed. Wherein, the water temperature of the cultivation pond is controlled at 10° C., and the dissolved oxygen in the water is controlled at 10 mg / L. On average, each broodstock is fed with 4% of its body weight by the weight of the special feed for broodstock every day. The special feed for broodstock is prepared from the following raw materials in parts by weight: 55 parts of soybean meal, 35 parts of bone meal, 25 parts of fish meal, 7 parts of silkworm chrysalis, 7 parts of choline chloride, 0.4 part of calcium dihydroge...

Abstract

The invention discloses a method for improving quality of carp fry cultivation, and belongs to the technical field of aquaculture. The method comprises the following steps: selecting parent fish, cultivating the parent fish, promoting estrus of the parent fish, hatching fertilized ova and cultivating juvenile fish, wherein when the parent fish is cultivated, the parent fish is fed with parent fishspecial feed; the parent fish special feed contains soybean meal, bone meal, fish meal, silkworm chrysalis, choline chloride, calcium dihydrogen phosphate, vitamin premixed feed, yeast powder, garlic, salt and traditional Chinese medicine additives; and the traditional Chinese medicine additives include milkvetch root, radix codonopsitis, baical skullcap root, Chinese angelica, colla carapacis, twotoothed achyranthes root, sichuan lovage rhizome, bunge swallowwort root, officinal magnolia bark, immature orange fruit, liquorice root, mongolian dandelion herb, honeysuckle bud and flower, motherwort herb and opuntia dillenii. The method provided by the invention solves the problem of poor quality of the carp fry cultivation in a traditional carp breeding process.

Description

technical field [0001] The invention belongs to the technical field of aquaculture, and in particular relates to a method for improving the quality of carp nursery. Background technique [0002] Commonly known as carp guaizi, Maozi, etc., carp belongs to Cyprinidae. Its body is flat on the side and round on the abdomen, with a horseshoe-shaped mouth, two pairs of whiskers, a long base of the dorsal fin, and a thick and serrated hard spine on the dorsal and anal fins. , the lower leaves of the caudal fin are orange-red. Carp usually inhabit the bottom of water bodies overgrown with aquatic plants in rivers, lakes, reservoirs, and ponds, and mainly feed on benthic animals. Carp has strong adaptability, cold resistance, alkali resistance, and hypoxia resistance. It can lay eggs in running water or still water. The spawning places are mostly in aquatic plants, and the eggs adhere to aquatic plants to develop. Carp is one of the freshwater fishes with the most varieties, the wi...
