Abstract
The utility model relates to a crab cage rearing module device, comprising crab cages and a buoy device, wherein the buoy device consists of a long buoy, a short buoy, right-angled turning joints, tee joints and cross joints; the long buoy and the short buoy are hollow cylindrical casings; the right-angled turning joints, the tee joints or the cross joints are mounted at the two ends of the long buoy and the short buoy to form multiple rectangular frames; the width of each rectangular frame corresponds to the length of each crab cage, and the length of each rectangular frame is integral multiples of the width of each crab cage; and the crab cages are arranged in the rectangular frames, each crab cage is a rectangular box body with a plurality of through holes, an opening is arranged in the top of each crab cage, a cover is mounted on each crab cage, a flange is arranged at the opening position of each crab cage, and each flange at the opening position of each crab cage is larger than the width of the corresponding rectangular frame. With the crab cage rearing module device, the cultivation density is improved, the killing of crab seedlings is reduced, the diseases are reduced, and the crab cage rearing module device can be applicable to the production of soft crabs of blue crabs.
Description
Technical field
The utility model belongs to the aquaculture tool technical field, particularly relates to a kind of crab class modular device of raising in cages.
Background technology
Crab is one of important aquatic products of China, and is delicious with its meat flavour, nutritious and liked by everybody.But because its cultured area per unit area yield is low, and the cannibalisation rate is high, the easy infection germ, and survival rate is lower, and the cultivation difficulty is larger.Especially domestic common mariculture kind mud crab and swimming crab, the cultivation survival rate of crab class is at 10-20% under traditional breeding way, and per unit area yield only has 50-150 kg/acre, differs greatly with other breed varieties such as prawns.Its topmost reason is that the crayfish culture space availability ratio is low, and the phenomenon that cuts one another's throat is serious, and breeding way is demanded urgently breaking through.
Summary of the invention
Technical problem to be solved in the utility model provides a kind of crab class modular device of raising in cages, and improving cultivation density, reduce cannibalisation, to reduce disease generation texts, and can be applicable to the mud crab soft crab and produces.
The technical scheme that its technical problem that solves the utility model adopts is: a kind of crab class modular device of raising in cages is provided, comprise crab pot and device with float, described device with float is by long floating drum, short floating drum, the right-angled bend joint, three-way connection and cruciform joint form, described long floating drum and short floating drum are the cylindrical housings of hollow, the right-angled bend joint is installed at described long floating drum and short floating drum two ends, three-way connection or cruciform joint consist of several rectangle frames, described rectangle frame width is corresponding with described crab pot length, the length of rectangle frame is the integral multiple of described crab pot width, described some crab pots are placed in the rectangle frame, described crab pot is a rectangular box that has some through holes, opening and lid is installed above the described crab pot, opening part has flange above the described crab pot, and described crab pot opening part flange is greater than the rectangle frame width.
Described long floating drum, short floating drum, right-angled bend joint, three-way connection and cruciform joint are made of plastics.
At least settle 2 crab pots in the described rectangle frame that is consisted of by long floating drum, short floating drum, right-angled bend joint, three-way connection and cruciform joint.
Beneficial effect
Use device of the present utility model to cultivate, greatly improved the survival rate of crab class, per mu yield is multiplied, and compares with domestic present cultural method, it is advantageous that:
(1) increased cultivation density, be increased to about 4000 every mu by original every mu hundreds of;
(2) avoid cutting one another's throat between the crab class fully, improved the survival rate of crab class;
(3) can check at any time the in time residual bait of cleaning of the situation of ingesting, not only can effectively control the bait feeding amount, can also avoid water quality to degenerate;
(4) can in time find the disease crab, and directly the crab of cultivation be processed, not need the water body in full pond is processed; Simultaneously can also do sth. in advance the processing time, improve treatment effect, prevent the disease diffusion, save the drug use amount, thereby reduced the impact on environment;
(5) but the state of each breeding cage of manual control be placed in the water, perhaps take out separately and do to reveal;
(6) compare with traditional cage catching mode, time point and the quantity of gathering in the crops into crab can arbitrarily control, and workload is little, is not subjected to the restriction of weather, time, and without omission;
(7) can put into same cage layer to the male and female crab that selects and carry out one to one mating, make things convenient for carrying out of breeding work;
(8) can arbitrarily control the size in the collocation of module and the shape of module group.
