Abstract

The invention discloses an early-stage cultivation method for hatched young misgurnus anguillicaudatus and relates to the field of aquaculture. Within three days after young misgurnus anguillicaudatus is hatched, all yolks disappear, mouth parts are formed, and boiled egg yolks start to be fed by a person. The method comprises the following steps: boiling eggs, taking out the egg yolks, and filling the egg yolks in a 120-mesh silk bag for pinching and washing; splashing an egg yolk suspension, and feeding the young misgurnus anguillicaudatus, wherein water flow in a loop for hatching the young misgurnus anguillicaudatus decelerates during feeding, the feeding amount of the young misgurnus anguillicaudatus on the first day is 10/1000,000, the feeding amount of the young misgurnus anguillicaudatus on the second day is 15/1000,000, and the feeding amount of the young misgurnus anguillicaudatus on the third day is 20/1000,000; feeding the young misgurnus anguillicaudatus for four times every day; after the young misgurnus anguillicaudatus is fed for three days and the color of the young misgurnus anguillicaudatus body changes from black into light yellow, taking the misgurnus anguillicaudatus out of a pond, and performing summer flower cultivation. The method is simple in operation process; the quick growth of the young misgurnus anguillicaudatus can be promoted; the young misgurnus anguillicaudatus is fed with the egg yolks and soybean milk, the growth of zooplankton in a water body inside a cultivation pond can be promoted, and the zooplankton can serve as natural baits of the young misgurnus anguillicaudatus; with milk powder added into the soybean milk and a traditional Chinese medicine composition water extract, the growth of the young misgurnus anguillicaudatus can be promoted, the resistance of the young misgurnus anguillicaudatus can be improved, the stress response to the environment is reduced, and the survival rate of the young misgurnus anguillicaudatus is improved.

Description

Breeding method in early stage after a kind of loach seedling hatching
Technical field
The present invention relates to aquaculture field, relate in particular to the breeding method in early stage after a kind of loach seedling hatching.
Background technology
Loach (Misgurnusanguillicaudatus) has higher nutrition and medical value, and at home and abroad on market, demand is larger, and price is better, propagates profit artificially high, instant effect, cultivation promise well.The cultured area of domestic loach is 1,500 ten thousand~2,000 ten thousand square metres, mainly concentrates on the ground such as Jiangsu, Henan, Hubei, Shandong, Anhui and Sichuan, and aquaculture model is mainly that pond purse seine has soil cultivation.The principal element of restriction loach breeding benefit is that loach growth rate is slow at present, and a year growth rate is difficult to reach more than 3 times; Loach parent seed selection, reinforced cultivating are one of sport technique segments important and crucial in loach artificial breeding.After loach spawning and hatching goes out loach seedling, need to carry out meticulous especially feeding and management to loach seedling, in loach artificial culture technology, it is immature that loach Early seedling stage is cultivated technology at present, and loach death of seedling rate is higher.
Summary of the invention
Technical problem to be solved by this invention is to overcome the defect of prior art, further proposes the breeding method in early stage after a kind of loach seedling hatching.
Technical problem to be solved by this invention realizes by the following technical solutions.
Breeding method in early stage after a kind of loach seedling hatching, it is characterized in that: loach seedling is hatched latter 3 days, yolk all disappears, mouthpart forms, start manually to throw something and feed, the yolk of throwing something and feeding and boiling, method is that egg is boiled, taking-up yolk is contained in 120 mesh sieve thin,tough silk bags to be pinched and washes, getting yolk suspension splashes and throws something and feeds, while throwing something and feeding, for hatching the circuit current of loach seedling, slow down, feeding volume is 10 of every 1,000,000 tail seedling first days, 15 of second days, the 3rd day 20, throw something and feed every day four times, throw something and feed after three days, seedling body color is transformed into when faint yellow by black, just can go out pond and proceed to the fry culturing stage,
Fry culturing, adopt loach seed rearing pond to cultivate, put the seedling sterilization of cleaning up the pond in first 10 days, then water filling is 20 centimetres, execute appropriate fertilizer and cultivate food organisms, treat that the property of medicine disappears, water colour just can be thrown seedling after turing green and occurring great quantity of small zooplankton, cultivates 40 square metres of pool areas, 10 centimetres of humus soil of cement pit bottom paving, while putting seedling, the depth of water is 40 centimetres, stocking rate 2500 tails/square metre, every pond 100,000 tails;
Loach seedling proceeds to be cultivated behind pond, adopt soya-bean milk cultivating method to cultivate loach seedling, soya-bean milk can not only directly be ingested by loach seedling, can also cultivate the zooplankton in water body, after loach seedling lower storage reservoir, splash every day 4 times, consumption is every 100,000 tail loach seedling every days with 0.75 kilogram of soya bean soya-bean milk, in soya-bean milk, add a small amount of yolk, milk powder and traditional Chinese medicine composition water extract and throw something and feed in the lump, can promote loach seedling Rapid development and improve resistance; After two weeks, change and feed manufactured feed, fixed point is thrown something and fed, and adds animality fresh feed, every day at the upper and lower noon each once, with loach seedling, eat up as degree in 2~4 hours.
Traditional Chinese medicine composition water extract is to filter the liquid obtaining after being decocted by Chinese medicine composition water, and Chinese medicine composition comprises the raw material of following weight portion:
15 parts of the Radixs Astragali, 10 parts of the bighead atractylodes rhizomes, 20 parts, French beans, 15 parts, raw Radix Glycyrrhizae, 20 parts of dried orange peels, 4 parts, raw lotus leaf, 8 parts of folium isatidiss, 7 parts, wax gourd, 5 parts of dandelions.
Change and feed after manufactured feed, cultivate depth of water and be controlled at 0.3~0.5 meter, within every three days, exchange a part of water yield, when 30 ℃ of temperature are above, add a cover sunshade net, eliminate harmful animal, by the special pond of 30 days, cultivate, loach seedling grows to 3~5 centimetres, can proceed to the breeding of mature loach stage.
Beneficial effect of the present invention is:
Breeding method in early stage after loach seedling hatching provided by the invention, operating process is simple, can promote seedling Fast Growth, when adopting yolk and soya-bean milk to throw something and feed loach seedling, also can promote to cultivate the zooplankton growth in pool inner water body, zooplankton can be used as the natural bait of loach seedling, the milk powder adding in soya-bean milk and traditional Chinese medicine composition water extract not only can promote the growth of loach seedling, can also improve the resistance of loach seedling, reduce to environment stress, improve the survival rate of loach seedling.
