Abstract
The invention relates to a two-crops-in-one-year artificial breeding technology of non-polluted freshwater shrimps. The technology comprises the steps that after being arranged and sterilized, a breeding pond is injected with new water and fertilized, and juvenile shrimps are put into the breeding pond to be bred; the two-crops-in-one-year breeding mode is adopted, and the juvenile shrimps are put into the breeding pond in March and July in the same year respectively; the shrimps are caught in June and January, and the breeding pond is cleared; feedstuff is put regularly in a quantified mode in the breeding period, and the mixed breeding mode is adopted in the second crop. The technology can effectively increase the yield and benefits of the freshwater shrimps and promote the development of the freshwater shrimp breeding industry.
Description
Technical field
The present invention relates to the nuisanceless freshwater shrimp artificial culture technology of a kind of two crops in one year, particularly relating to can the nuisanceless large-scale farming freshwater shrimp of scale, improves output, increases economic benefit.
Background technology
Freshwater shrimp formal name used at school Japanese macrobrachium supernbum is the fresh water shrimp that economic benefit is very high, is Crustachia, Decapoda, shrimp section.It extensively originates in China fresh water lake, delicious meat, and nutritious, protein content is high, belongs to famous and precious aquatic products.So serious owing to fishing for, and the backwardness of cultural technique, cause the reduction of germ plasm resource degeneration and freshwater shrimp quality.Unreasonable due to cultivation, expansion scale blindly, does not bring the raising of quality and the increase of economic benefit, cause freshwater shrimp to occur on the contrary hatching is abnormal, sexual maturity in advance, the situation such as the incidence of disease is high.How to pass through the artificial propagation techniques of improvement freshwater shrimp, by non-nuisance, ensure its Quality and yield, increase economic efficiency, become the Main way of research.
Summary of the invention
The object of the present invention is to provide a kind of more effective nuisanceless freshwater shrimp artificial propagation techniques, improve quality, the increase yield of freshwater shrimp.
The technical scheme that the present invention solves the problems of the technologies described above is as follows: the nuisanceless freshwater shrimp artificial culture technology of a kind of two crops in one year, comprises the following steps:
All need before input to arrange culturing pool, adopt quicklime to throw in sterilization;
After injecting new water, execute fermentation fertilizer 200kg, after 1 week, put juvenile prawn in a suitable place to breed for every mu;
Start March to throw in first batch, feed of throwing something and feeding at regular time and quantity, rise April and fish for, by the end of June the dry pool;
Early July puts second batch in a suitable place to breed, raises together with, feed of throwing something and feeding at regular time and quantity, rises December and fishes for, and January in next year cleans up the pond.
On the basis of technique scheme, the present invention can also do following improvement:
Culturing pool area is moderate, arranges multiple pools mouth, depth of water 1.3m, and slope is than 1:3, smooth at the bottom of pond, and substrate is black earth clay, the thick 5-10cm of mud; Side of a pond shoal plantation water peanut, wide 1.5m, face, pond pasture and water coverage rate is more than 30%; Fishpond is by every mu of 100kg lime disinfection, and inject the dark new water of 60cm, organic fertilizer 200kg/ mu cultivates water quality, can put juvenile prawn in a suitable place to breed after 1 week; The breeding mouth of a river, pond adopts diagonal way to arrange, and water inlet is more than face, pond, and discharge outlet and the water surface are with high, and gauze seals, and prevents the harm of the animals such as snake, the frog, mouse; Establish one, aerator simultaneously.
Described first batch of concrete steps of putting juvenile prawn in a suitable place to breed are as follows further:
The noon that early March weather is fine throws in, and stocking size is 1000 tails/kg, throws in 6.5kg, monoculture for every mu, and juvenile prawn needs physique healthy and strong, anosis without wound.
Described first batch of concrete steps of throwing something and feeding are as follows further:
Threw something and fed before April rice bran, flour, wheat bran, 5d throws in once, and injected volume is 1.5% of shrimp body gross weight; Arrange in pairs or groups after April broken spiral shell, small fish is rotten, and 1d throws in once, and injected volume is 2% of shrimp body gross weight; When more than 18 DEG C the morning 10 time, respectively throw in once when afternoon 6, injected volume is 1.5% of shrimp body gross weight.
Described first batch of concrete steps of fishing for are as follows further:
Freshwater shrimp is fished for from April, uses cage harvesting, after working continuously 5 days, has a rest one week, catch stay greatly little, the dry pool by the end of June.
Described second batch of concrete steps of raising together with juvenile prawn are as follows further:
Early July weather is thrown at fine noon, and stocking size is 1000 tails/kg, throws in 7kg for every mu, and juvenile prawn needs physique healthy and strong, anosisly raises together with summer flower variegated carp, megalobrama amblycephala without wound, throws in summer flower variegated carp, each 600 tails of megalobrama amblycephala for every mu.
Described second batch of concrete steps of throwing something and feeding are as follows further:
Feed of throwing something and feeding only throws full-valence pellet feed, adds a small amount of fresh and alive small fish, 2 times/d, more than 25 DEG C, throws something and feeds 3 times, and the morning, once in afternoon twice, injected volume was about 4% of shrimp body gross weight; Adjust according to actual conditions.
Described second batch of concrete steps of fishing for are as follows further:
Freshwater shrimp is fished for from December, uses cage harvesting, after working continuously 5 days, has a rest one week; Last a small amount of diddle-net that adopts is fished for, and January in next year cleans up the pond.
The invention has the beneficial effects as follows:
Freshwater shrimp grows neatly, and survival rate is high; Non-nuisance, quality is high; Two crops in one year and raise together with mode, output is high, high financial profit;
Embodiment
Build 200hm
2breeding farm, point 16, large pulk mouth, depth of water 1.3m, slope is than 1:3, smooth at the bottom of pond, and substrate is that black earth sticks scholar, the thick 5 ~ 10cm of mud, and the row of filling is convenient, and water source used all meets fishery water standard, pH value 7 ~ 8, and each pool mouth joins 2 3kW aerators.The thick 5-10cm of mud, side of a pond shoal plantation water peanut, wide 1.5m, sterilizes breeding farm, fertilising.Water temperature more than 20 DEG C, early March throws in first batch, juvenile prawn 7000 tails/mu, and vegetable feed of only throwing something and feeding before April, comprises rice bran.Flour, wheat bran, 5d throws in once, and injected volume is 1.5% of shrimp body gross weight; Arrange in pairs or groups after the April broken spiral shell of feed of animal origin, small fish is rotten, and 1d throws in once, and injected volume is 2% of shrimp body gross weight; When more than 18 DEG C the morning 10 time, respectively throw in once when afternoon 6, injected volume is 1.5% of shrimp body gross weight.Start April to fish for successively, catch and stay greatly little, June does the pool.Early July puts second batch in a suitable place to breed, raises together with, and only throws full-valence pellet feed, adds a small amount of fresh and alive small fish, 2 times/d, more than 25 DEG C, throws something and feeds 3 times, and the morning, once in afternoon twice, injected volume was about 4% of shrimp body gross weight; According to actual conditions adjustment, January in next year cleans up the pond.
