Abstract
The invention relates to a layered cage rearing device and a using method thereof. The cage rearing device comprises at least one cage body, wherein the cages are overlaid to form a group; a movable feeding door is arranged on the lateral side of the cage body; round holes are formed on the cage separator and coaming of the cage body; the cage body is formed by two pairs of symmetric arc edges and straight edges; a plurality of through holes are formed symmetrically on the outer rims of the arc edges; and a lantern ring is arranged in the center of the top of the cage body. By using the device and the method, the raising density is increased to 4,000 to 12,000 crabs per Mu from hundreds of crabs per Mu, 6 to 20 crabs can be reared in every square meter (on square meters, the raising density includes soil pond raising, and also can be used as calculation bases for indoor high-density raising), so that mutual killing among crabs is completely avoided, and the survival rate of the crabs is improved.
Description
Technical field
The invention belongs to aquatic breed field, particularly relate to the raise in cages using method of device and this device of a kind of layering that is used for crayfish culture.
Background technology
Crab is one of important aquatic products of China, and is with its meat flavour deliciousness, nutritious and liked by everybody.But because its cultured area per unit area yield is low, and cannibalisation rate height, the easy infection germ, survival rate is lower, and the breed difficulty is bigger.Especially domestic common mariculture kind mud crab and swimming crab, the breed survival rate of crab class is at 10-20% under traditional breeding way, and per unit area yield has only 50-150 kilogram/mu, differs greatly with other breed varieties such as prawns.Its most important 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
Technology crayfish culture per unit area yield to be solved by this invention hangs down problem, and provide a kind of by improve cultivation density, reduce cannibalisation, device and using method thereof are raised in cages in the layering that reduces effects such as disease generation.
A kind of layering device of raising in cages, the described device of raising in cages comprises the cage body of being made up of cage layer dividing plate and coaming plate, the described device of raising in cages is at least one cage body, between the described cage body by being superposed to one group up and down, described cage body side surface is provided with activity bait throwing in door, is provided with circular hole on the cage layer dividing plate of described cage body and the coaming plate, and described cage body is made of two pairs of symmetrical arc limit and straight lines, outer, described arc limit symmetry offers several through holes, and described cage body top center position is provided with the collar.
Described cage body is a plastic material, and is superposed to one group up and down with 6.
The length of described every group of cage body is 41cm, and wide is 36cm, and height is 72cm.
The through hole that passes each layer by rope between the described cage body closes up the back stack.
Described activity bait throwing in door is provided with movable button and circular hole.
A kind of raise in cages method of device of above-mentioned layering of using comprises the following steps:
(1) adopting the layering device of raising in cages, is one group with 6 cage bodies, puts a crab for every layer;
The density of (2) placing in water is with 1～3 group/m
2, in the small size cement pit, culture, above cement pit, shelve bamboo pole, the layering device of raising in cages is hung on bamboo pole; Culture in large-area pond, the parallel hawser that draws supports hawser with timber above the pond, and the layering device of raising in cages is hung on the hawser; Also can hang the layering device of raising in cages with the fixed point buoyant raft, hitch point is aligned, and whenever stays the canoe navigation of water surface passage for bait throwing in, observation in the ranks;
(3) according to cultivation density air feed equipment is set, is beneficial to survival environment for the crab in the device of raising in cages provides;
(4) invalid individuality is taken out in bait throwing in every day twice, and the growth and the disease situation of observing crab, replenishes new healthy individual;
(5) regularly do the whole device of dew, promote the normal shell of crab class.
Beneficial effect
Use device of the present invention to culture, improved the survival rate of crab class greatly, per mu yield is multiplied, and compares with domestic present cultural method, it is advantageous that:
(1) increased cultivation density, be increased to 4000～12000 every mu by original every mu hundreds of, every square can support 6～20 (by square, it is pool cultivated promptly to comprise soil, can be used as the basis of indoor highly dense breed again);
(2) avoid cutting one another's throat between the crab class fully, improved the survival rate of crab class;
(3) can check the situation of the ingesting residual bait of cleaning in time at any time, 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 culturing be handled, not need the water body in full pond is handled; Simultaneously can also do sth. in advance the processing time, improve treatment effect, prevent the disease diffusion, save the drug use amount, thereby reduced influence environment;
(5) the dried dew time be can artificially control, the shell and the growth of crab class promoted;
(6) compare with traditional ground 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 does not have omission;
(7) can put into same cage layer to the male and female crab that selects and carry out mating one to one, make things convenient for carrying out of breeding work.
