Abstract
The invention discloses an efficient ecological crab breeding method and belongs to the field of aquaculture. The efficient ecological crab breeding method includes digging a crab pond, laying 5-10cm thick silt at the bed of the pond, and setting up an anti-escape net around the crab pond; cleaning the pond in winter, and scattering 120-160kg of quick slim per acre; transplanting waterweeds in the pond in February to March in the next year, applying 20-30kg of organic fertilizer per acre, putting in crab seeds for breeding, keeping the water temperature at 5-10 DEG C for the crab seeds, and putting in crucian summerlings at the same time; putting in 300-500kg of snail per acre from April to July, putting in 70-80 silver carp summerlings per acre on June to July, and applying phycomycetes fertilizer on July to August while enhancing fertilizer management to prevent disease damage. The crucian and the silver carp are intercropped with the crab, water environment is improved by the aid of the snail and the waterweeds, reasonable fertilizer management is performed, and accordingly large-weight river crabs can be cultivated efficiently. In addition, the intercropping increases breeding benefit.
Description
Technical field
The present invention relates to aquaculture field, specifically design a kind of ecological efficiently crab cultural method.
Background technology
At present, the crab cultural technique reaches its maturity under people's exploration, but the breed of most crab remains single aquaculture model, and only the breed to river crab is difficult to make maximization of economic benefit.But present cover is supported, ecologic breeding still lacks successful technical experience and guidance; Tradition crab pool environment might not be fit to the growth of other species; Adding needs preparation rationally, food chain is to satisfy different plant species coexistence in the crab pond efficiently, and the crab pond is raised together with pattern and is in the exploratory stage always.
Summary of the invention
Goal of the invention: the purpose of this invention is to provide a kind of ecological efficiently crab cultural method of raising together with crucian and silver carp.
Technical scheme: in order to realize the foregoing invention purpose, a kind of ecological efficiently crab cultural method of the present invention comprises the steps:
(1) excavation crab pond, and at the bottom of the pond, lay 5 ~ 10cm mud, and build the anti-net of escaping around in the crab pond;
(2) clean up the pond winter, mu is splashed with 120 ~ 160kg quicklime, adds water; Begin in the pond, to transplant pasture and water then 2 ~ March of next year, mu organic fertilizer 20 ~ 30kg puts juvenile crab then in a suitable place to breed, and said water temperature of putting juvenile crab in a suitable place to breed is 5 ~ 10 degrees centigrade, throws in the crucian summer flower simultaneously;
(3) from April ~ July mu throw in spiral shell 300 ~ 500kg, in 6 ~ July mu throw in silver carp summer flower 70 ~ 80 tails, throw in phycomycete fertilizer to 7 ~ August, during strengthen feed management, prevent disease.
Wherein, the feed management behind the input juvenile crab comprises: crab is adopted frozen fish feed and artifical compound feed to cooperate with feed and throws in, and the injected volume in 3 ~ April accounts for 3 ~ 5% of river crab body weight, and the injected volume after May brings up to 6 ~ 9%.
The present invention not only can improve the feed intake of river crab through throwing in crucian and silver carp, also can improve the water body quality.
Adopt the zinc sulphate pulvis to shed water surface desinsection in the infusorian high-incidence season, utilize C5H6Br2N2O2 simultaneously water body disinfection.
Beneficial effect: a kind of ecological efficiently crab cultural method of the present invention is on the basis that crab is cultured; Cover is supported crucian and silver carp, improves water body environment through screw and pasture and water, in conjunction with rational feed management; But high-efficient culture goes out the river crab of high body weight, supports through cover simultaneously and improves culture benefit.
Embodiment
Through embodiment the present invention is further specified below.
A kind of ecological efficiently crab cultural method comprises the steps:
(1) excavation crab pond, and at the bottom of the pond, lay 5 ~ 10cm mud, and build the anti-net of escaping around in the crab pond;
(2) clean up the pond winter, mu is splashed with 120 ~ 160kg quicklime, adds water; Begin in the pond, to transplant pasture and water then 2 ~ March of next year, mu organic fertilizer 20 ~ 30kg puts juvenile crab then in a suitable place to breed, and said water temperature of putting juvenile crab in a suitable place to breed is 5 ~ 10 degrees centigrade, throws in the crucian summer flower simultaneously;
(3) from April ~ July mu throw in spiral shell 300 ~ 500kg, in 6 ~ July mu throw in silver carp summer flower 70 ~ 80 tails, throw in phycomycete fertilizer to 7 ~ August, during strengthen feed management, prevent disease.
Wherein, the feed management behind the input juvenile crab comprises: crab is adopted frozen fish feed and artifical compound feed to cooperate with feed and throws in, and the injected volume in 3 ~ April accounts for 3 ~ 5% of river crab body weight, and the injected volume after May brings up to 6 ~ 9%.
Wherein,, not only can improve the feed intake of river crab, also can improve the water body quality through throwing in crucian and silver carp.
Adopt the zinc sulphate pulvis to shed water surface desinsection in the infusorian high-incidence season, utilize C5H6Br2N2O2 simultaneously water body disinfection.
The above only is a preferred implementation of the present invention; Be noted that for those skilled in the art; Under the prerequisite that does not break away from the principle of the invention, can also make some improvement and retouching, these improvement and retouching also should be regarded as protection scope of the present invention.
