Abstract
The invention discloses a kind of cultural method of Micropterus salmonoides, comprise the following steps：The preparation of culture pond, put in a suitable place to breed it is preceding prepare, net cage classification, classification are fed, water quality management and fished for.The cultural method of the Micropterus salmonoides of the present invention uses the breeding way of culture pond combination aquaculture net cage, good growing environment is provided for the growth of Micropterus salmonoides, comprehensive nutrition is provided for the growth of Micropterus salmonoides by scientific and reasonable forage compounding, and the method fed using classification cultivation and gradient, effectively prevent because in feeding process individual difference too greatly caused by the situation that cuts one another's throats, improve the survival rate of fry, it is ensured that the economic benefit of raiser.
Description
Technical field
The invention belongs to technical field of aquaculture, and in particular to a kind of cultural method of Micropterus salmonoides.
Background technology
Micropterus salmonoides original name Micropterus salmoides, belongs to Perciformes, Sunfishes, rich in thiamine, protein, riboflavin, cigarette
A variety of human bodies such as acid, dietary fiber, vitamin C, vitamin E, vitamin A, cholesterol, carrotene, retinol, magnesium, copper, selenium
Required nutritional ingredient, being capable of nourishing liver and kidney taste, also effective in cure to cold cough；In addition, perch can also control fetal irritability, life
The diseases such as the few breast of production, ready-to-be mother and puerpera eat perch and can mend body, do not result in overnutrition again and cause obesity, are that body-building is mended
Blood, strengthening the spleen and replenishing qi and the safe and comfortable good merchantable brand of beneficial body.
The breeding way survival rate of Micropterus salmonoides is low at present, density is low, the speed of growth is slow, deficiency in economic performance, Micropterus salmonoides
Although can natural spawning in the pool pure and fresh in water quality, with pasture and water, spawning rate is low, and fry size is uneven, easily from mutually residual
Kill, and the bad control of cultivation density, individual size heterogeneityization is serious.In breeding process, food nutrition also not comprehensively, mainly with
Chilled fish or lower trash fish are bait, and vitamin and mineral supply is not enough；In addition, to water quality requirement in Micropterus salmonoides breeding process
Also very strict, agricultural chemicals and water pollution can all cause disease and the death of Micropterus salmonoides.For these reasons, it is necessary to existing
Micropterus salmonoides propagate artificially, seedling-raising technique is improved improvement, with improve propagate quality artificially.
The content of the invention
The invention provides a kind of cultural method of Micropterus salmonoides, existing Micropterus salmonoides cultural method survival rate is solved
Low, density is low, the speed of growth is slow, deficiency in economic performance the problem of.
The invention provides a kind of cultural method of Micropterus salmonoides, comprise the following steps：
Step 1, the preparation of culture pond：Select abundant water, the pure and fresh free of contamination water head site of water quality, water head site physical features compared with
Pond is transformed or newly dug to lower, and pond bottom compacting is laid two relative side walls in 15-20cm 37 lime earth, pond and set
It is in 120 ° -150 ° of slope to be set to pond bottom, and two other relative side wall is vertical with pond bottom, close perpendicular to pond
Two side-walls of pool bottom are mounted on aquaculture net cage, and oxygenation is also equipped with close to two side-walls perpendicular to pond bottom
Machine；
Step 2, preceding preparation is put in a suitable place to breed：Breed fish fry first half of the month, select fine day afternoon 3 when after pond is disappeared
One week is stood after poison, sanitized, then toward filling new water in pond, standing three days after new water filling is finished, then toward in pond
The chicken manure become thoroughly decomposed is delivered, injected volume is 70-90Kg/ mus, when observing that water quality is micro- green or micro- brown, open the oxygenation in pond
