Description
Technical field
The present invention relates to shrimp culture technical field, particularly relate to the method for intensive hatching freshwater shrimp in a kind of cement pit.
Background technology
Freshwater shrimp (Macrobrachiumnipponensis), formal name used at school Japanese macrobrachium supernbum, belongs to Crustachia, Decapoda, Palaemonidae.Be strong adaptability in freshwater, distribution is wide, feeding habits are mixed, grow fast, fine and tender taste, the famous and precious aquatic products that delicious in taste, economic worth is very high, deeply look at by consumer parent.The major production areas of freshwater shrimp is in the Yangtze river basin, and all there is breeding scale on the ground such as Jiangsu, Anhui, Shanghai, Zhejiang, Fujian, Jiangxi, Guangdong, Hunan, Hubei, Sichuan, Hebei, Henan, Shandong.The cultivation gross yield of whole nation freshwater shrimp is all at about 220,000 t, and wherein Jiangsu Province's output is the highest, accounts for about 46% of national output, is secondly Anhui (accounting for 18%), Zhejiang (accounting for 9%), Hubei (accounting for 9%).
Cultivation, the raising technology of China freshwater shrimp just began one's study at the end of the nineties.But for many years, the fine-variety breeding of freshwater shrimp and the artificial breeding technique of seed scale are not yet broken through.Enter 21 century, due to the increase with market demand that improves constantly of people's level of consumption, the natural output of freshwater shrimp reduces in addition, and colony's specification reduces, and the output of freshwater shrimp can not meet the needs of domestic market, more can not meet the needs of overseas market.Therefore, the provinces and cities such as Hubei, Anhui, Zhejiang, Shanghai are studied the breeding of freshwater shrimp, cultivation, but because the freshwater shrimp life-span is short, fertility is strong, and pond culture specification is irregular, and size difference is larger, cultured output is always lower, culturist does not reach desirable benefit, and add that freshwater shrimp kind matter is degenerated serious in recent years, colony's specification is less than normal; Commodity rate is low, thus causes the area of shrimp culture and output to be difficult to expand and improve always.
Along with the continuous expansion of shrimp culture scale, the develop rapidly of production, also there are problems in shrimp culture industry, as uneven in shrimp culture technical merit, cultural technique is lack of standardization, and freshwater shrimp kind matter is degenerated, and sexual maturity ahead of time, disease increases, pattern is single etc., causes freshwater shrimp commodity rate low, and grade declines, the market competitiveness is not strong, has a strong impact on the sound development of shrimp culture.
Freshwater shrimp kind matter is degenerated, freshwater shrimp shrimp seedling is under-supply.
Freshwater shrimp is strong adaptability in freshwater, distribution is wide, feeding habits are mixed, it is fast to grow, fine and tender taste, the famous and precious aquatic products that delicious in taste, economic worth is very high, deeply looks at by consumer parent.Anhui Province's water surface aboundresources, be the important cultivation area of freshwater shrimp, output is only second to Jiangsu, and because freshwater shrimp market price remains high always, fisherman is always very high to the cultivation enthusiasm of freshwater shrimp.
But the deficiency of shrimp seedling, the especially deficiency of high-quality shrimp seedling, limit the expansion of shrimp culture scale, become the bottleneck of freshwater shrimp industry development; Because cultural technique is lack of standardization, cause freshwater shrimp kind matter to be degenerated, make shrimp culture family decline in benefits; Seed rearing survival rate is on the low side, makes raiser take in minimizing.
Select the freshwater shrimp kind that proterties is excellent, ensure the supply of high-quality freshwater shrimp seed, specification freshwater shrimp seed rearing and one-tenth shrimp aquaculture technology, become the problem that freshwater shrimp industry development need solve.
Summary of the invention
The object of the present invention is to provide the method for intensive hatching freshwater shrimp in a kind of cement pit, to solve the problem.
Technical problem to be solved by this invention realizes by the following technical solutions:
A method for intensive hatching freshwater shrimp in cement pit, it is characterized in that, in indoor water mud sump, throw in close shrimp carry out seedling hatching, close shrimp is placed in net cage, is placed with weter hyacinth in net cage, and the management method between the incubation period is as follows:
(1) length and width, deeply respectively 5m, 3m and 1.2m of cement pit, 3/4 of cement pit volume is filled in cement pit, filter with 80 eye mesh screens during water filling, Xiang Shuizhong drops into, fruit of Cherokee rose 35g, thizoma curculiginis 65g, PORIA ALBA 48g, fruit of glossy privet 55g, bark of eucommia 76g, Radix Glycyrrhizae 95g;
(2) throwing is raised, and feed throws in bait disc ad hoc in net cage or on weter hyacinth, bait throwing in should be appropriate, eats up as degree in 1-2 hour;
(3) oxygenation, Bubbled stone 8-10 is established in every pond, every day While settling increase the oxygen, to guarantee that pond water-soluble oxygen is sufficient, the blowing pressure forms bubble with Bubbled stone and does not dig the spray at water surface and be advisable in water;
(4) water is changed in blowdown, cement pit blowdown rubber tube, is absorbed by the dirt sunk to the bottom, then pours into new water to former water level; Blowdown every day 1 time, supplements new water to former water level at every turn again after changing water liquid level decline 5-10cm; After changing water at every turn, the fruit of Cherokee rose of the immersion in cement pit, thizoma curculiginis, PORIA ALBA, the fruit of glossy privet, the bark of eucommia, Radix Glycyrrhizae are pulled out, again drops into, fruit of Cherokee rose 3.5g, thizoma curculiginis 6.5g, PORIA ALBA 4.8g, fruit of glossy privet 5.5g, bark of eucommia 7.6g, Radix Glycyrrhizae 9.5g;
(5) check hatching situation in time, every day checks, shrimp of not only will checkmating skims, and also the complete close shrimp of hatching will be sorted out to sell or put back to parent Chi Jixu and feed, use for next time again; Should carefully operate, in order to avoid shrimp body is frightened injured during inspection.
Energising in described cement pit, water flowing, ventilation; Before putting seedling, first scrubbed clean by cement pit, then add water, Xiang Shuizhong adds bleaching powder 1.5-2ppm and carries out disinfection, then is bled off by water, new water of again annotating.
Described cage size 2m × 1m × 1m, mesh goes out not go with prawn, and the young can freely be come in and gone out as principle.
The invention has the beneficial effects as follows:
Method of the present invention can realize intensive hatching in indoor, and incubation condition is convenient to control, and in unit are, incubation rate is high, and the freshwater shrimp seedling hatched is physically fit, and survival rate is high, fishes for conveniently.
