Abstract
The invention relates to a breeding device, in particular to a large-scale grouper breeding device employing a large outdoor fish pond. The invention aims to solve the problems that during the current process from the growth stage of fertilized eggs of groupers to the initial feeding stage, a great amount of larval fish dies, the facility investment at the earlier stage of current artificial breeding is higher, more links are involved, the operation is complicated, the hatching water and farming water cannot circulate mutually, the nurture environment is changed, and the larval fish cannot be placed in the original incubator facility for a long time, so that the survival rate of fry is extremely low, and even the mass death of a great amount of fry is caused. A rainproof awning is bound with a supporting framework, four sides of an opening of a hatching bag are bound at the lower parts of four parallel sides of the supporting framework, a parallel opening is formed in any side wall by shearing and sewed with a group of upper and lower zippers, the parallel opening is sealed through a filter screen sewed on the inner side of the parallel opening, a filtering window comprises a group of zippers and a filter screen, and an air pump is communicated with an inflation pipe and a plurality of air connectors. The large-scale grouper breeding device is used for large-scale grouper breeding.
Description
Technical field
The present invention relates to the fish hatching and breed industry, particularly relate to outdoor large-scale fish pond propagation in scale fry.
Background technology
Ablen fertilized egg is the less transparent float gamogenetic egg in ovum footpath, and existing to utilize outdoor large-scale fish pond artificial propagation in scale ablen fry be all can control under the Marine water condition, cardinal principle is to utilize the buoyancy of fertilized egg to wait for by being placed on fertilized egg dividing in a plurality of small waters that passively the fertilized egg cell divides, until the prelarva opening, then scoop out and put into the extensive hatching of large-scale fish pond (1900-6600 cubic meter) realization; Main incubator, as grouper fertilized egg is rendered in a plurality of cement pits, is scooped out and is put into fish pond after the prelarva opening; Grouper fertilized egg is rendered in a plurality of hatching pails, after the prelarva opening, scooped out and put into fish pond.Find by test that ablen prelarva opening is scooped out to put into behind fish pond and gather a large amount of fresh water in fish pond and the spray as heavy rain, strong wind, cause fish pond salinity instantaneous variation, raindrop are pounded upstream face, due to alevin stage individuality little, slim and frahile, can't survive.And existing artificial culturing method link is many, complex operation, easily causes prelarva to be hit and damage rear death; Observe because ablen incubating oosperm water quality and the fish pond water quality that will put into cultivation can not be consistent at any time, fry can not adapt to new water body environment at once, produces stress reaction, and mortality; The nurturing an environment change causes fry opening feed immediately, further causes large quantities of death of fry; Can not be placed on for a long time after the prelarva opening in the small water of former hatching and cultivate, must scoop out and put into fish pond.Therefore propagation in scale ablen fry is subject to long-term obstruction.
Summary of the invention
The objective of the invention is to grow into prelarva mortality in opening feed process in order to solve existing ablen fertilized egg, existing artificial breeding facility investment in early stage is larger, implement the link multioperation loaded down with trivial details, after ablen prelarva opening, as the heavy rain strong wind, in large-scale fish pond, can't survive, the hatching water quality causes the prelarva mortality with the inconsistent generation stress reaction of fish pond water quality that will put into cultivation, nurturing an environment changes fry opening feed immediately and causes large quantities of death of fry, can not be placed on for a long time in former hatching facility the problem that survival rate is extremely low that causes of cultivating after the prelarva opening, the outdoor large-scale fish pond of a kind of ablen propagation in scale device has been proposed.
The present invention solves the problems of the technologies described above the technical scheme of taking to be: described breeding device comprises anti-rain awning, support frame, incubation bag, filter window, air pump, the main gas charge pipe, gas tube, the gas head, the rain-proof sunshade cloth that described anti-rain awning also evenly nails on core by four limit bound edges is made, one side is by the support frame back timber, " people " word shape two bottom sides is bundled into one with the parallel corresponding both sides tension of support frame respectively, described support frame is cut off to glued joint by plastic pipe to be made, back timber is close to the anti-rain awning middle part, parallel corresponding both sides are bundled into one with anti-rain awning " people " word shape two bottom sides respectively, parallel four binding incubation bag opening four limits, bottom, limit, described incubation bag consists of support frame and filter window, described incubation bag by waterproof cloth make make bottom lock upper opening four limit bound edges evenly nail core is arranged, square with degree of depth is bag-shaped, sidewall cuts flat the row mouth and sews up slide fastener and lower slide fastener on one group arbitrarily, wherein on every group parallel with lower slide fastener mouthful of position of slide fastener by making the parallel mouthful of screen pack shutoff that place is inboard, parallel four bottoms, limit of described support frame and incubation bag opening four limits are bundled into one, described filter window consists of one group of slide fastener and a screen pack, every group of parallel sewing up on the incubation bag sidewall of described slide fastener, every of described screen pack is made parallel mouthful of every group of slide fastener position shutoff of incubation bag inside sidewalls, described air pump is communicated with the main gas charge pipe, described main gas charge pipe is communicated with a plurality of gas head gas tubes, described gas tube is communicated with a plurality of gas heads respectively.
The present invention has following beneficial effect, and the anti-rain awning of incubation bag of the present invention can be resisted heavy rain, strong wind, the sun and tan by the sun, and has guaranteed ablen fertilized egg until the normal growth of prelarva opening; Incubation bag is arranged in outdoor large-scale fish pond, and the incubation bag prelarva of untiing binding can easily enter fish pond, and the workflow simple operations is convenient; After opening filter window, in the incubation bag water quality short time, can be consistent with cultivation fish pond water quality; The filter window of opening has guaranteed that the interior water body of incubation bag and fish pond flow mutually, can be placed on for a long time in former hatching facility and cultivate after the prelarva opening; Compare with existing artificial breeding grouper method, hatch the facility self-control early stage simply, small investment, popularize easily; Implement link few, easy to operate, can be untied as required at any time incubation bag and be put prelarva to the operation in fish pond, avoided prelarva to be hit dead after damage; Avoid running into the heavy rain strong wind and caused can't surviving of opening prelarva; Because inside and outside water body flows mutually, avoided fertilized egg to grow into prelarva mortality in opening feed process; Avoided the prelarva mortality caused due to nurturing an environment change generation stress reaction and opening feed immediately; Avoided can not being placed on for a long time the low survival rate caused in former hatching facility after the prelarva opening.
