Abstract
The present invention relates to a kind of freshwater shrimp fry Collocation cultivation method, it is related to aquaculture field, comprises the following steps：Shrimp ponds requirement, shrimp ponds processing, cross mating, shrimp seedling is put in a suitable place to breed, feeding manages, water quality management, density domination, the present invention makes full use of the resources of production of free time, Standard cultivation technology, by by after Taihu Lake youth shrimp and local shrimp cross mating, obtain high-quality seed and carry out cultivation cultivation, and to during the breeding of the freshwater shrimp second generation, breed fish fry, on the one hand just regard the feed of fry, on the other hand those small shrimp seedlings are eaten up, retaining space, oxygen consumption is reduced, ensure that freshwater shrimp specification is neat, yield is high.
Description
Technical field
The present invention relates to aquaculture field, more particularly to a kind of freshwater shrimp fry Collocation cultivation method.
Background technology
Freshwater shrimp, scientific name Macrobrachium nipponensis (Macrobrachium nipponense), category shell-fish, Decapoda, swimming suborder,
Eucyphidea, long-armed section, pond crayfish category, a fairly large number of one kind in fresh water shrimp, one of traditional economy shrimp species in China's freshwater aquaculture industry.
Because cultivation freshwater shrimp disease is more at present, cost is high, pollution is big, and cultivation freshwater shrimp enthusiasm is not high, cause a large amount of ponds half uncultivated or
It is idle；Furthermore in propagating artificially, freshwater shrimp specification is small, and feed coefficient is big, causes the vicious circle of freshwater shrimp inbreeding, cultural technique
The problems such as lack of standardization, cannot solve.
In addition because the shrimp seedling supported down in 7-8 months starts amount reproduction second generation shrimp seedling again to September part, they and
The freshwater shrimp for having grown a period of time robs feed and eaten, and also to occupy space in pond, absorb oxygen, the pretty good freshwater shrimp of growing way before being allowed to
Good growing environment is lost, certain difficulty is all brought to feeding management etc., it is uneven to go out the freshwater shrimp head on the pool in the end,
Commercial sized prawn is very poor, and yield is very low, and benefit is naturally bad.
The content of the invention
In view of the above-mentioned problems, the invention provides a kind of improved seeds by after local shrimp and the hybridization of Taihu Lake youth shrimp,
Cultivate the freshwater shrimp fry Collocation cultivation method for coordinating fry to cultivate together after a period of time.
The present invention is achieved by the following technical solutions：A kind of freshwater shrimp fry Collocation cultivation method, comprises the following steps：
(1) shrimp ponds requirement：Nursery pool area 3-5 mus are advisable, and depth of water 1.0-1.2m, bottom of pond is flat, remove mud and are allowed to not
More than 10 centimeters；
(2) shrimp ponds are handled：Cultivated including shrimp ponds sterilization, shrimp pond water quality；
(3) cross mating：Hybridized with the female shrimp from high-quality population and local male shrimp；
(4) shrimp seedling is put in a suitable place to breed：Late July puts the tails of shrimp seedling 6-8 ten thousand in a suitable place to breed for every mu to early August；
(5) management is fed；
(6) water quality management：Water colour keeps highest water with light rice-pudding color or yellow green, transparency 30-40cm, summer and autumn high warm season
Position, every to change water for 8-10 days once, quantity of exchanged water 1/4；
(7) density domination：Every mu of freshwater shrimp pond of September part can breed fish fry 3000 tails.
Preferably, in step 2, quick lime or bleaching powder or bleaching powder can be used in freshwater shrimp pond, injects 20-30cm clear water,
Substrate is carried out disinfection and improved, is drained after 24h.
Preferably, after being sterilized in pond, then enter filter water 30-40cm, and discharge aquaculture special bio fertilizer and contain
The beneficial organism fertilizer formulations of bacillus, for cultivating water quality.
Preferably, in step 3, hybridized using the young female shrimp in Taihu Lake with local male shrimp 2: 1.
Preferably, in step 5, within 10-15 days early stage, combination feed is fed, surrounding is splashed in pond after being mixed thoroughly with water；
Shrimp is grown to 2cm, can feed pellet.
It is tuned into preferably, described combination feed is plant feed and animal fodder in 7: 3 ratios；Feeding volume
Can be eaten up and be defined in 2-3 hours by shrimp, fed the 3-5% that rate is freshwater shrimp body weight days, feed in two times, during morning 8-9, afternoon 4-
When 5, the feeding volume morning accounts for 1/3, in afternoon 2/3, throws in surrounding shoal, is hidden by day and come out at night habit according to freshwater shrimp, is growing vigorous season,
At night after 10 points plus 1 time.
This invention takes above-mentioned corrective measure progress, its advantage is notable：The present invention makes full use of the production of free time
Resource, without increasing professional equipment, no breeding pollution, administrative staff are industrialized, cultural technique standard criterion, discharge biological agent
Water quality is controlled, the use of medicine is reduced, freshwater shrimp is reached pollution-free healthy requirement, improves product quality value.
In addition, the high-quality shrimp seedling after cross mating can play hybrid vigour, the speed of growth, disease-resistant anti-adversity ability are being improved
With delay sexal maturity etc., than traditional local shrimp parent culture go out shrimp seedling improves significantly.
After shrimp seed rearing two months or so, start to breed the second generation, bred fish fry in pond, just will just hatch what is come
Freshwater shrimp is eaten in the presence of feed, and the first generation has also grown into enough big individual, and to pool listing is gone out, commercial sized prawn specification is neat, yield
It is high by more than 30%, and more than 100 jins of fry, economic benefit greatly improves.By the big specification freshwater shrimp 150kg of the cultivation per mu yields of 2 years,
Tradition cultivation freshwater shrimp output increased 60% on year-on-year basis, unit price improve 40%, and economic benefit improves 120%.
Embodiment
With reference to embodiment, the present invention is further illustrated：Experiment is carried out in Jing Zhou.
Embodiment
A kind of freshwater shrimp fry Collocation cultivation method, comprises the following steps：
(1) shrimp ponds requirement：3 mu of nursery pool area is advisable, and depth of water 1.0m, bottom of pond is flat, removes mud and is allowed to be not more than 10
Centimetre；
(2) shrimp ponds are handled：Quick lime is used in freshwater shrimp pond, 20cm clear water is injected, carries out disinfection and improve substrate, 24h heel row
Fall, after being sterilized in pond, then enter filter water 30cm, and discharge aquaculture special bio fertilizer and the beneficial organism containing bacillus
Fertilizer formulations, for cultivating water quality；
(3) cross mating：(female shrimp and local male shrimp use are hybridized using the young female shrimp in Taihu Lake and local male shrimp 2: 1
Conventional equipment is caught, screened)；
