Abstract
The present invention discloses a black carp fry breeding method and belongs to the field of fry breeding. The method comprises the following steps of: pond preparation, fry breeding, fry stocking and feeding management. The pond preparation is to prepare a pond with an area of 1000-2000 m<2>, a depth of 1-1.5m and a sludge thickness less than 20cm, and clear the pond 15 days before fry stocking. The seedling breeding is to fertilize 5500-6500 kg/ha of green manure or 3500-4500 kg/ha of manure 4-7 days beforestocking the fry, and ferment, compost and disinfect the green manure or the manure by 1-2% lime. And then the water in the pond is deepened to 0.5m after 4-5 days of fertilization and to 0.6-0.7m after 5 days of fertilization. A dense net is used to perform filtering during the process of water inlet. The technological means is capable of improving the survival rate of black carp fry and producing robust and strong fry, thereby improving the ability thereof to resist illness.
Description
Technical field
The present invention relates to nursery to cultivate, especially a kind of black carp seeding cultivating method.
Background technology

Black carp is one of four large Chinese carps, except containing except abundant protein, fat in black carp, also containing the abundant trace element such as selenium, iodine, therefore has anti-ageing, antitumaous effect.Be rich in nucleic acid in the flesh of fish, this is the necessary material of human body cell, nucleic acid food delaying sanility, the treatment of aided disease.
The present stage cultivation of black carp seedling uses conventional methods, and the survival rate of fry is general, can not meet the need of market.
Summary of the invention
Goal of the invention of the present invention is: for above-mentioned Problems existing, and provide a kind of black carp seeding cultivating method, can improve the survival rate of fry, fry is strong, strong, and the ability of resist the disease is also improved.
The technical solution used in the present invention is as follows: black carp seeding cultivating method, comprises the following steps: pond prepares, and nursery is cultivated, and fry is put in a suitable place to breed, feeding and management;
Described pond is prepared as pond area 1000-2000m
2, the dark 1-1.5m in pond, silt depth <20cm, fry is cleaned up the pond before putting 15 days in a suitable place to breed;
Described nursery is cultivated as putting 4-7 days green manuring 5500-6500kg/ hectares or muck 3500-4500kg/ hectare before seedling, green manure or muck fermentation, become thoroughly decomposed and use 1-2% lime disinfection, apply fertilizer after 4-5 days, water to be added and be deep to 0.5 meter, add after 5 days and be deep to 0.6-0.7 rice, during water inlet, use close net filtration;
Described fry is put in a suitable place to breed as selecting fine day to be in the wind place, and the input membrane postlarva of 7-8 days, breeding density 100-150 ten thousand fishes/ha, when putting in a suitable place to breed, water temperature and the outdoor temperature difference are no more than 2 DEG C.
Preferably, described feeding and management is that fry puts 1-10 days soya-bean milk of throwing something and feeding in a suitable place to breed, wherein first 5 days 33kg/ hectares, latter 5 days 38kg/ hectares, every day 2 times, and full pool spilling head is even, and every the 6-8 days 15-20cm that add water, soya-bean milk of throwing something and feeding after 10 days accounted for the 5-7% of total fry body weight.
Preferably, in feeding and management when the cultivation fry of 25 days grows to more than 3cm, the pond depth of water adds to 1.3-1.5m.
In sum, owing to have employed technique scheme, the invention has the beneficial effects as follows: adopt above-mentioned technological means can improve the survival rate of black carp seedling, the fry of output is strong, strong, and the ability of resist the disease is also improved.
