Abstract
The invention discloses a river crab culture device and a special culture pond, and provides a hole-dwelling river crab culture mode under the running water condition. For solving the problem, the river crab culture device is characterized by comprising a pipeline of which one end is closed and the other end is connected with a netty crab pot, the upper end of the netty crab pot is provided with a netty pot cover, and the lower end of the netty crab pot is provided with a bait chamber. The river crab culture device and the special culture pond effectively overcome several defects of the traditional river crab culture, large river crabs can be cultured at low cost and risk and high delicacy. By culturing the river crabs in the mode, the bait utilization rate is improved by 60 percent, the survival rate is improved by 30 percent, and the average mass of the river crabs in the same period is increased by 20-30 percent compared with that in the traditional culture.
Description
Technical field
The invention belongs to aquaculture field, be specifically related to a kind of culture of Chinese mitten crab device and special-purpose culturing pool.
Background technology
The cultivation of existing river crab is many carries out the extensive style cultivation in lake, river, artificial pond, its major defect is: the survival rate that can't precisely know the river crab early, middle, late stage; Can't constantly guarantee the interior requirement to every key elements such as water quality, dissolved oxygen, pH values of river crab growth cycle; Can't accurately know the bait picked-up situation of every river crab, river crab thrown in too much mistake I haven't seen you for ages by bait and water quality exerts an influence, and can cause the death of river crab when serious; Shelling and growing state that can't every river crab of accurate recording, thus meticulous aquaculture management can't be accomplished; Collective fishes for and can cause the river crab damage, affects survival rate.
Summary of the invention
The technical problem to be solved in the present invention provides a kind of hole under the running water condition and occupies formula culture of Chinese mitten crab mode.
For addressing the above problem, the technical solution used in the present invention comprises a kind of culture of Chinese mitten crab device, it is characterized in that: described crab cultivator comprises pipeline, described pipeline one end is closed, the other end connects netted crab pot, and described netted crab pot upper end arranges netted cage lid, and the lower end arranges the bait chamber.
Described culture of Chinese mitten crab device is characterized in that: described netted cage lid front end arranges hook.
A kind of special-purpose culturing pool of river crab of realizing according to described crab cultivator, it is characterized in that the special-purpose culturing pool of described river crab comprises the first cistern, the first sedimentation basin, the sand filter of connection, described sand filter with one roughly the water inlet in S-shaped pond be connected, be inserted with one group of described culture of Chinese mitten crab device on the pool wall in described pond, the delivery port in described pond connects the second cistern, the second sedimentation basin, clear water reserviors successively, described clear water reserviors one end arranges the backwater hidden pipe, and the other end of described backwater hidden pipe is connected with the first cistern by water pump.
The special-purpose culturing pool of described river crab is characterized in that described the second cistern, the second sedimentation basin, clear water reserviors are provided with the discharge of wastewater mouth.
The special-purpose culturing pool of described river crab is characterized in that on the described pond heat preservation greenhouse being set.
The culture of Chinese mitten crab device of reality of the present invention and special-purpose culturing pool have effectively overcome the some shortcomings of traditional culture of Chinese mitten crab, can do the on earth river crab of cost, end risk, fine, the large specification of cultivation.By the manner cultivating river crab, bait utilization improves 60%, and survival rate improves 30%, increases 20-30% with river crab average body amount in the cycle than the tradition cultivation.
Description of drawings
The present invention is further detailed explanation below in conjunction with the drawings and specific embodiments.
Fig. 1 is the structural representation of culture of Chinese mitten crab device of the present invention.
Fig. 2 is the structural representation of the special-purpose culturing pool of river crab of the present invention.
Embodiment
As shown in Figure 1, the new described crab cultivator a of this practicality comprises cylindrical tube 1, and described pipeline 1 one ends are closed, and the other end connects the crab pot 2 made from nylon wire, and described crab pot 2 also is cylindricality, and its upper end arranges netted cage lid 3, and the lower end arranges bait chamber 4.The specification of described pipeline 1 is diameter 10-12cm, height 60-80cm, and the specification of described crab pot 2 is diameter 12-14cm, height 30-40cm.For preventing that river crab from escaping from crab pot, described netted cage covers 3 front ends hook 5 is set.It is the ventilative and requirement of creeping that guarantees river crab that described crab pot 2 and cage lid 3 all adopt network structure.
As shown in Figure 2, a kind of special-purpose culturing pool of river crab of realizing according to the crab cultivator, comprise the first cistern 6 that is communicated with by pipeline or water channel, the first sedimentation basin 7, sand filter 8, described sand filter 8 with one roughly the water inlet 10 in S-shaped pond 9 be connected, the pond 9 of described S shape is by the stacked bar earthwork 19 in the middle of a square pond, the earthwork 19 two ends reserve the flowing water road junction, then at the flowing water road junction at interval gate 20 is set, thereby form the pond 9 of a continuous S shape, the pond 9 of S shape can guarantee the circulation of pool inner water, can place again simultaneously more crab cultivator, be inserted with several culture of Chinese mitten crab devices a on the pool wall in described pond 9, every cube of normal conditions are put 8-12, the delivery port 11 in described pond 9 connects the second cistern 12 successively, the second sedimentation basin 13, clear water reserviors 14, described clear water reserviors 14 1 ends arrange backwater hidden pipe 15, and the other end of described backwater hidden pipe 15 is connected with the first cistern 6 by water pump 16.
Be provided with discharge of wastewater mouth 17 at the second cistern 12, the second sedimentation basin 13, clear water reserviors 14, can discharge the waste water in the pond, 9 arrange heat preservation greenhouse 18 in the pond, the heat preservation greenhouse 18 general forms that sun net and plastic foil are set at support that adopt, effectively the temperature in the balancing tank guarantees the growth of river crab.
The pond operation principle: the water source flows to the first cistern 6, enter the first sedimentation basin 7, sand filter pond, 8 shallow lake and filtration, clean water is flow to pond 9, then by the second cistern 12, the second sedimentation basin 13,14 pairs of used water of clear water reserviors form sediment pond and filtration, the water pump 16 of the other end by backwater hidden pipe 15 is evacuated to the first cistern 6 with water at last, forms a circulation.
The above only is preferred embodiment of the present invention, not in order to limiting the present invention, all any modifications of doing within the spirit and principles in the present invention, is equal to and replaces and improvement etc., all is included within protection scope of the present invention.
