Abstract
The invention relates to a crab roe culturing method in a high density crab roe culturing tank of blue crabs, relating to an aquiculture method, and providing a crab roe culturing method in a high density crab roe culturing tank with high culturing density, high survival rate and high weight growth rate during the culturing period, and the method can enhance the culturing quality of the blue crabs. The crab roe culturing facilities: the crab roe culturing tank made of stones and bricks, etc., with the wall height of the crab roe culturing tank lightly lower than that of a neap tide, the tank depth of 1.5 to 2.0m, and area of 200 to 500m<2>; the crab roe culturing tank is provided with a water inlet and a water outlet, the bottom of the tank is a layer of sand with a shielding object positioned, the tank mouth is tightly covered with a steel sheet, and the water in the tank is replaced twice every day when the tide comes. The crab roe culturing measures are that: mated female crabs with complete appendages are divided into two kinds: one kind is just mated female crabs, and the other is the female crabs mated for one month, and the two kinds are cultured respectively, with a culturing density of the female crabs being 5 to 10crabs/m<2>; the daily feeding quantity of small fishes and shrimps is controlled between 5 to 12 percent of the total weight of the blue crab, and that of low value small shellfishes is controlled between 20 to 35 percent of the total weight of the blue crab, and all foods are cast once respectively in the morning and evening.
Description
Technical field
The present invention relates to a kind of aquaculture method, especially relate to a kind of high-density blue crab fat-breeding method in fat-breeding pool that promotes the female crab weight increase and the development of ovary.
Background technology
The mud crab build is big, growth is fast, delicious meat, is China's important mariculture crab class in south.Sexually matured female crab because of the crust both sides are full of red ovary, is called as " Hong Gao Charybdis "." Hong Gao Charybdis " tasty, nutritious, favored by the consumer deeply.Employing is manually educated the cream technology thin crab is fattened short cream, has the advantage of culture-cycle weak point and remarkable in economical benefits.Educate at present the cream technology mainly adopt soil pool cultivated urge cream fatten (the Chen Fen Son. mud crab is urged cream and fattens Synergistic technique, and science is breeded fish, 2004,10:26-27).But Tu Chi educates, and cream faces that mud crab cuts one another's throats, disease propagation and the wayward equivalent risk of condition of water quality, educates cream specification requirement height.
Summary of the invention
The objective of the invention is at the existing problem of the pool cultivated mud crab of soil, provide a kind of mud crab educate the cream cultivation density, culture during mud crab survival rate and rate of body weight gain height, can improve the high-density blue crab fat-breeding method in fat-breeding pool of blue crab cultivation quality.
Concrete grammar of the present invention is as follows:
1) educate cream pond facility: educate the cream pond and build, educate cream pond pool wall height a little less than little tidal height with materials such as stone, bricks, the dark 1.5～2.0m in pond, area is at 200～500m
2, to educate the cream pond and be provided with water inlet and discharge outlet, the shop sand bed is placed veil at the bottom of the pond, the tight-lipped cover net sheet in pond, the tide of receiving every day changes water 2 times;
2) educate the cream measure:
(1) select that appendage is complete, the female crab of mating by the female crab of firm mating and one month female crab classification of mating put in a suitable place to breed;
(2) 5～15/m of breeding density
2
(3) strengthen raising: day throwing amount of raising a small fish shrimp is controlled at 5%～12% of mud crab TBW; Low value band shell shellfish is controlled at 20%～35% of mud crab TBW, divides sooner or later and throws for 2 times;
3) harvest: educate catch during the cream fertilizer stay thin, multiple stocking and multiple fishing.
Educate the cream pond and preferably be chosen in the middle low tidal region of the harder beach in reclamation area, inner bay substrate or rock phase, sandy intertidal zone.The sand bed thickness of educating at the bottom of the pond, cream pond is preferably 10～15cm, and veil is preferably earthen-ware pipe, pipe of cement etc., and the net sheet is preferably 2 layers of polyethylene net sheets, mesh 1～2cm.
The 9th side tooth has the semilune ovary one to the optic stalk base portion to the firm female crab of mating from the crust both sides, with hand extruding abdomen navel top, the visible big milky round dot of soya bean; One month female crab ovary of mating enlarges gradually, underfill crust edge still, and light is observed down, visible some transparent places, abdomen navel top round dot transfers yellow to by milky.Low value band shell shellfish is selected from oyster, pushes up at least a in clam, blue clam, short tooth clam, the spiral shell etc. partially, can be controlled in 20%～35% of mud crab TBW.Described branch is thrown for 2 times sooner or later can adopt upslide 30%～40% early, throws 60%～70% evening.
Compare with existing blue crab cultivation method, the present invention has following outstanding advantage: mud crab educates the cream pond and is chosen in low tidal region in the marine site, and the tide of can receiving every day changes water 2 times, and it is abundant to change water, and condition of water quality is good, does not need spended time to regulate and control water quality meticulously, and operation is simple.It is low to educate the cream breeding process mud crab incidence of disease, need not medication.The present invention has reached and has improved the purpose that mud crab educates the cream quality and increases income, and the mud crab survival rate is more than 90% during the breed, rate of body weight gain about 15%.
