Abstract
The invention discloses a method for culturing soft blue crabs indoors. The method comprises the following steps of: constructing a culture pond; making culture baskets; arranging the culture baskets; stocking crabs to be cultured; managing the culture and collecting soft crabs. Horizontal shelves are arranged in the culture pond so that water and air in the culture baskets are favorably exchanged like in natural environment. Meanwhile, dirt in the culture baskets is lessened to benefit the growth of the blue crabs in the baskets and lessen diseases, the culture baskets are respectively provided with hidden chambers containing sediment to naturally accommodate the blue crabs, benefit the growth of the blue crabs, reduce the interference of outside on the growth of the blue crabs and improve the survival rate, and the blue crabs are cultured in respective culture baskets to avoid a phenomenon of mutual fighting among individuals and improve the survival rate in the culture process. Accordingly, the method for culturing soft blue crabs indoors has higher survival rate and good culture benefits.
Description
Technical field
The present invention relates to cultivate the method for soft crab, be specifically related to the method for a kind of indoor culture Portunus trituberculatus Miers soft crab.
Background technology
Portunus trituberculatus Miers is important seafood, be loved by the people, and soft crab is because full crab softness, and the fertile full crab of meat is edible, and instant, liked by people.The crab kind of cultivating soft crab at present comprises blue crab, mud crab and Portunus trituberculatus Miers etc.As publication number is CN101755679A, name is called " method of producing soft crab with Portunus trituberculatus Miers ", the Portunus trituberculatus Miers of not finishing the reproduction shelling that discloses 50～250 grams is transported to indoor, pack in the cylinder mould of adding a cover, cylinder mould is placed in the shell pond cultures, cultivate and comprise inflation at the bottom of the pond, the management of pH value, dissolved oxygen, salinity, water temperature, bait throwing in etc., checked Portunus trituberculatus Miers shelling and death state in the cylinder mould in per 2～4 hours, in time handle.The many crabs of this method cylinder mould are placed directly at the bottom of the pond with foster, cylinder mould, and do not have hidden and the shading condition, and Portunus trituberculatus Miers is affected by environment bigger, and survival rate is lower, and culture benefit is relatively poor.
Summary of the invention
It is higher that technical problem to be solved by this invention provides a kind of survival rate, and culture benefit is the method for indoor culture Portunus trituberculatus Miers soft crab preferably.
The present invention solves the problems of the technologies described above the technical scheme that is adopted: the method for a kind of indoor culture Portunus trituberculatus Miers soft crab comprises the steps:
A, culture the pond and make up: building at indoor cement is 50～60 centimetres breed pond deeply, pool inner water is 30～35 centimetres deeply, be provided with gas tube at the bottom of the pond in described breed pond, vertically be provided with at least two row of horizontal shelves at the bottom of the pond in described breed pond, described horizontal shelf height is 5～10 centimetres, wide is 10～20 centimetres, and the spacing of adjacent two horizontal shelves is 60～80 centimetres; Breed pond size is pressed careat and is decided, and horizontal shelf row number is decided by culturing the pond size, can establish two rows, four rows, five rows, eight row of horizontal shelves etc.;
B, culture the basket preparation: forming the limit basket with plastics is that 30～40 centimetres, height are 40～50 centimetres breed basket, the long limit basket and the end basket of this breed basket all are provided with the flowing flux that width is not more than 1 centimetre, be provided with undercovert in the described breed basket, described undercovert height is 15～20 centimetres, fill silt in the described undercovert, the thickness of described silt is 10～15 centimetres; Undercovert can allow Portunus trituberculatus Miers have nature and perch part, help the Portunus trituberculatus Miers growth, reduce the interference of outer its growth of bound pair, improved survival rate, Portunus trituberculatus Miers is hidden to get final product the undercovert length and width allowing, and generally is about 10 centimetres, shelve more steady in order to make the breed basket at horizontal shelf, undercovert is located near culturing the basket middle part, and the flowing flux effect is to change water, gets final product not allow Portunus trituberculatus Miers climb out of;
C, breed basket are shelved: described breed basket is intersected shelve on the described horizontal shelf; Horizontal shelf can allow cultures basket and leaves at the bottom of the pond, also can change the water ventilation under end basket, cultures a water in the basket, the gas exchange is preferable, and is similar to natural environment, cultures simultaneously that a dirt reduces in the basket, helps interior the Portunus trituberculatus Miers of basket and grows, the minimizing disease;
D, crab to be prepared are put in a suitable place to breed: one of monoculture reaches listing specification Portunus trituberculatus Miers in described breed frame, carries out the soft crab cultivation;
E, aquaculture management: comprise that timing is thrown something and fed, timing is removed residual bait, oxygenation, changed water and disease control, regularly the time of throwing something and feeding is every day 17～18 o'clock, every day, feeding volume was 5～10% of a Portunus trituberculatus Miers body weight, the bait of throwing something and feeding is trash fish and manufactured feed, regularly remove residual bait and be every day 7～8 o'clock, water transparency is no less than 30 centimetres;
F, soft crab are gathered: during the Portunus trituberculatus Miers shelling of cultivating, checked one time Portunus trituberculatus Miers shelling situation every 2～3 hours, the soft crab that collection has in time shelled, frozen, owing between adjacent two row of horizontal shelves spacing is arranged, order is examined the state that just can understand Portunus trituberculatus Miers, need not the pull-up of breed basket can not alarmed Portunus trituberculatus Miers.
Compared with prior art, the invention has the advantages that the method for a kind of indoor culture Portunus trituberculatus Miers soft crab, comprise that culturing the pond makes up, culture the basket preparation, culturing basket shelves, crab to be prepared is put in a suitable place to breed, aquaculture management and soft crab acquisition step, be provided with horizontal shelf by culturing in the pond, can make and culture water in the basket, the gas exchange is preferable, similar to natural environment, culture dirt reduction in the basket simultaneously, help a basket interior Portunus trituberculatus Miers growth, reduce disease, culture in the basket and be provided with the undercovert that fills silt, allow Portunus trituberculatus Miers have nature and perch part, it is hidden to be convenient to swimming crab, reduced environment to external world stress, reduce the interference of outer its growth of bound pair, help the Portunus trituberculatus Miers growth, improved survival rate, each cultures monoculture cultivation soft crab in the frame, has avoided the phenomenon that cuts one another's throats between the individuality, and the survival rate of cultivating process is improved, therefore the present invention is that a kind of survival rate is higher, and culture benefit is the method for indoor culture Portunus trituberculatus Miers soft crab preferably.
