Abstract
The invention relates to the field of aquaculture, and specifically relates to a crab culturing method. According to the method, through pond environment control and scientific culturing, crabs are kept away from heavy pollution hazards, crab survival rate is improved, and crab development and growth can be stimulated. With the method, crab growth speed is accelerated, crabs are clean and safe, crab quality is better, and crab meat is firm. Therefore, good economic benefit can be provided.
Description
Technical field
The present invention relates to aquaculture field, relate to the cultural method of a kind of crab in particular.
Technical background
Crab, also known as river crab, is fresh water crustacean, grows up in fresh water, crab delicious, nutritious.Crab is at present by Chinese and the universally recognized cuisines of overseas people, at present because the source of crab is still to fish for, it is less that artificial culture work is carried out, the crab of self-sow can not meet the eating requirements of people far away, although rely on the cultivation of small size to carry out the needs in supplementary market in recent years, equally do not alleviate the demand in market yet.Crab contains rich in protein and trace element, has good tonic effect to health.Containing more vitamin A in crab, helpful to the angling of skin.Crab also has treating tuberculosis effect, and eating crab has help greatly to rehabilitation lungy.
Summary of the invention
The technical problem to be solved in the present invention is to provide the cultural method of a kind of crab.
For solving the problems of the technologies described above, the invention provides the cultural method of a kind of crab, comprising the following steps:
(1) construction in pond: select to have abundant water resources, water retention capacity is strong, and ecotope is good, pollution-free source around, fertile soil, the land development pond of substrate natural structure, area is 2.3-2.9 mu, pond is provided with water inlet and discharge outlet, and prevents escaping net in the installation of pond surrounding, is 1-1.5 rice deeply in the middle part of pond, be deeply 1 meter around, the depth of water is the half of the degree of depth, and bottom is provided with the mud of 0.3-0.5 rice, and every mu is provided with an aerator;
(2) put front preparation in a suitable place to breed: putting seedling first half of the month, carry out disinfection to spreading quicklime in pond, and plant a large amount of pasture and water, crab seedling is put into salt solution before putting in a suitable place to breed and soak 10 minutes;
(3) feedstuff feeding: do not feed in the week after putting in a suitable place to breed, after the week, feed dregs of beans and egg compound, dregs of beans and egg ratio are 9:1, throw in feed 3-4kg for every mu, each input sooner or later 1 time every day;
(4) water quality management: ensure that water temperature is at 15 DEG C-25 DEG C every day, change water in time and ensure water temperature, change weekly 1/3 water in pond, every two weeks spreads quicklime in pond, and drives aerator every day 2 hours.
Further, described every mu of cultivation 450 ~ 500.
Further, described anti-escape device is hard calcium-plastic board, and insertion depth is 50 meters.
The beneficial effect of employing technique scheme is: the cultural method of a kind of crab of the present invention, by the environment in pond and the cultivation of science, make crab away from the harm of heavily contaminated, improve the survival rate of crab, the growing of crab can be stimulated, make the growth rate of crab faster, clean safety, quality is better, and meat is solid, thus obtains good economic benefit.
