Abstract
The present invention is a kind of extensive family juvenile crab miniflow network of rivers case breeding method of river crab, belongs to aquatic products culture of Chinese mitten crab technical field.Trestle is specifically set up in pond, cross bar is set between trestle, net cage is hung on cross bar, adjusts water-adding system, and the water that net cage is added in control keeps net cage inside and outside in miniflow water state.The juvenile crab that a kind crab output is cultivated in each net cage, becomes a family.The present invention carries out in outdoor earth pond, and juvenile crab is subjected to a degree of exercise, quality naturally and is improved.One 2 mu of pond can cultivate 200 familys, substantially increase the scale and breeding process of breeding.The water in entire pond is in the state flowed always, it is ensured that the homogeneity of each family juvenile crab nurturing an environment, environmental deviation is smaller, and inherent cause is highlighted, and the comparativity between each family increases, and the accuracy of selection increases, and Breeding progress is accelerated.
Description
Technical field
The present invention relates to a kind of culturing and reproducing of aquatic products, especially a kind of breeding method of river crab juvenile crab, specifically
It is a kind of extensive family juvenile crab miniflow network of rivers case breeding method of river crab that ground, which is said, belongs to aquatic products culture of Chinese mitten crab technical field.
Background technique
River crab scientific name Eriocheir sinensis (Eriocheir sinsensis H.), is under the jurisdiction of Arthropoda, Crustachia, ten
Sufficient mesh, Grapsidae, bending of leg crab subfamily, Eriocheir.River crab meat flavour is delicious, full of nutrition, is a kind of depth by the favorite water of the masses
Product is the particularly important aquatic products economic living in China.With the continuous development of crab farming, the demand of river crab breeding is increasingly
Vigorous, river crab fine-variety breeding is increasingly by the attention of insider.At present river crab fine-variety breeding mainly use unexpected mass incident and
Two methods of family selective breeding, family selective breeding is because its fast feature that is in progress becomes preferred method.Existing family selective breeding side
Formula may be roughly divided into two classes, and one kind is to use the small-sized appearances such as hatching cylinder in workshop by the way of early stage shrimp crab industrial seedling rearing
(200 liters of volume or so) of device progress, one kind be use current mainstream river crab earth pond ecological seedling raising manners, build small-sized Tu Chi into
Row.Both of which is all haveed the defects that intrinsic, the former indoor raising of seedling mode is to have been produced the mode eliminated, output
Juvenile crab constitution it is weaker, later period cultivation survival rate is low, and soil pond quantity needed for the latter is more, at high cost and each pool environment homogeneity compared with
Difference, it is more difficult to form scale, these have all delayed the process of river crab good variety selection.
Summary of the invention
Needle indoor raising of seedling juvenile crab constitution of the present invention is weak, the mono- pond seedling raising environment homogeneity difference of Tu Chi problem at high cost, invention
A kind of breeding method of the extensive family river crab seedling of net cage miniflow water in native pond.The technical scheme is that a kind of river crab
Extensive family juvenile crab miniflow network of rivers case breeding method, it is characterized in that the following steps are included: the firstly, soil of 2~5 mu of sizes of selection
Pond is as culture pond, it is desirable that has individual culvert system, bottom of pond is flat, and pond is using preceding thoroughly removing mud；Secondly,
Trestle is set up in pond in parallel, cross bar is set up between two trestles, net cage water-adding system is installed in trestle side；Third, juvenile crab training
It educates and uses water process；4th, net cage is suspended on cross bar, kind crab is put into row children in net cage after being fitted into production seedling cage, after arranging children
Remove the production seedling cage equipped with kind of crab；5th, micro- running water technology juvenile crab, until growing up to megalops larva；Finally, whole pond water body treatment,
Each net cage individually fishes out seedling and puts in a suitable place to breed, and juvenile crab, which is cultivated, to terminate.The trestle, bridge floor is 1 meter wide, and bridge is 2 meters high, trestle spacing in pond
1.2 meters are arranged in parallel, and cross bar are set up between two bridges, bar is away from 1 meter.The net cage is pentahedron structure, with 80 mesh sieve tulles
It is fabricated to, the square that bottom surface is 1 meter of side length, 1.5 meters high, top-open, net cage is fixed on the rigidity that the materials such as reinforcing bar are made into
On skeleton, tighten bolting silk net open and flat.The net cage suspension 1000 square meter pond of quantity is no more than 200.The net cage
Water-adding system includes water pump, main pipeline, and branch pipe(tube) and regulating valve, branch pipe(tube) can go deep into lower 1 meter of net cage internal water, branch pipe(tube) end
It blocks, is spaced 10cm on underwater portion tube wall from top to bottom and opens 1 and iris out water hole, aperture 2mm, water hole side is respectively irised out in 8 holes of every circle
Dislocation is opened.The water process is that 20 days ponds are filtered into seawater, water inlet by 150 mesh sieve tulles bags before kind of crab row is young, the depth of water
1.8 meters, 15 days waters are successively sterilized using tea seed cake, bleaching powder before kind crab row is young, are inoculated within 10 days and are determined in pond before kind crab row children
To culture Chaetoceros and chlorella, water transparence is made to reach 20cm~30cm.Micro- running water technology juvenile crab is regulating valve
Door makes each net cage every 12 hours 1m3 water can be added.Fresh and alive wheel animalcule is fed into net cage daily, maintains wheel animalcule density in net cage
Not less than 500/L, wheel animalcule density is not less than 100/L outside net cage.The whole pond water body treatment is by being repeatedly discharged
Seawater in pond, be added equivalent fresh water mode carry out, each displacement be no more than 20cm, every 12 hours 1 time
Advantageous effect of the invention:
The present invention carries out in outdoor earth pond, and juvenile crab is subjected to a degree of exercise, quality naturally and is improved.Using net
One 2 mu of pond can under the premise of case nursery is ensuring to efficiently use Water space, and nonoverload guarantee condition of water quality is excellent
To cultivate 200 familys, the scale of breeding is substantially increased.Type of rearing is surveyed using miniflow water, it is ensured that the water in net cage
Matter is pure and fresh, reduces mesh blocking, and the wheel animalcule outside net cage can also be brought back in net cage, guarantees the bait of juvenile crab abundance
Supply.And the mode of flowing water makes the water in entire pond be in the state flowed always, it is ensured that each family juvenile crab cultivates ring
The homogeneity in border, environmental deviation is smaller, and inherent cause is highlighted, and the comparativity between each family increases, the accuracy of selection
Increase, Breeding progress is accelerated.
Detailed description of the invention:
