Description
Technical field
The utility model relates to technical field of aquaculture, particularly relates to a kind of incubating oosperm device in grouper artificial breeding is produced.
Background technology
Embryo development procedure and the influence factor of research aquatic livestock not only have scientific meaning, and contribute to the assurance of relevant art link in Seedling production.But, some aquatic livestock, as having the Shrimp waste animal of oogenesis habit, the more difficult acquisition of its fertilized egg; Or in sampling process, parent is died unexpectedly, and all can hinder follow-up research.Even to some directly by the kind that ovum produces in water, as the fish of majority, its incubating oosperm is also often subject to the harm of water mold, protozoa etc. under experimental conditions, causes hatching unsuccessfully.Because the existence of these problems, the environmental factors such as research water Inversion phenomenon are then more difficult on the impact of some kind embryonic development.Some rareness species, the kind that especially some egg load are less, its embryonic development research also can be subject to the puzzlement of the problems referred to above.Frequent sampling easily alarms parent, even causes abandoning ovum, not only delays research, and wastes the chance of seed breeding, affects the protection of rare species.In addition, during Shrimp waste biological engineering, the phenomenon dead after laying eggs of seed selection parent happens occasionally, and seriously will hinder the process of breeding.
Grouper, belong to Perciformes, body oblong is slightly flat-sided.Mouth is large, and tool supplemental maxillary, tooth apicule, what have is expanded into canine tooth.Body by little ctenoid scale, have often be embedded in subcutaneous.Dorsal fin and the prosperity of stern fin spine, tail fin circle or spill, variation in body color is a lot of, normal in brown or redness, and tool striped and spot, be the big-and-middle-sized seafood fish of water warm.Grouper is nutritious, and fine and tender taste is pure white, similar chicken, have the title of " extra large chicken ".Ablen fertilized egg is the less transparent float gamogenetic egg in ovum footpath, and existingly utilize outdoor large-scale fish pond artificial propagation in scale ablen fry to be under all can controlling Marine water condition, cardinal principle utilizes the buoyancy of fertilized egg to be placed on fertilized egg dividing in multiple small water to wait for that fertilized egg cell divides passively, until prelarva opening, then scoop out and put into large-scale fish pond (1900-6600 cubic meter) and realize extensive hatching; Main incubator, as rendered in multiple cement pit by grouper fertilized egg, is scooped out and is put into fish pond after prelarva opening; Grouper fertilized egg is rendered in multiple hatching pail, scoop out after prelarva opening and put into fish pond.By test find ablen prelarva opening scoop out put into fish pond after gather fish pond fresh water and the spray in a large number as heavy rain, strong wind, cause fish pond salinity instantaneous variation, raindrop pound upstream face, because individuality alevin stage is little, slim and frahile, cannot survive.
Prior art is that the plate that grouper fertilized egg is housed is sunk under water middle hatching, and such hatching pattern incubation rate is lower.Prior art be adopt to hang the method for ovum with ovum, exactly bolting silk is put into parent fish pond, fertilized egg is produced on bolting silk, injects after taking-up, the fertilized egg obtained so not only surface is clean, and transparency is also bad.
Utility model content
The purpose of this utility model is to overcome the deficiencies in the prior art, provide a kind of hatching apparatus of grouper fertilized egg, the manufacture of this device is cheap, quality is light, simple to operate, hatchability of fertile eggs is high, hatching water body is identical with seedling water, can not cause Early larval stress, hatchability of fertile eggs is high.
The utility model is achieved through the following technical solutions:
A kind of hatching apparatus of grouper fertilized egg, comprise main frame, incubation bag, sunshade net and aerating device, described main frame is that rectangular vinyl tube joins end to end and forms by four cross sections, on the vinyl tube of the length direction of described main frame, be provided with multiple foam plastic float; Described main frame is provided with four short support bars and two struts of drawing money on credit, the upper end of four short support bars and two struts of drawing money on credit is provided with sunshade net, described aerating device comprises 9 gas stones, and gas stone is arranged in the bottom of incubation bag, and gas stone is inflated by inflator pump.
Further, four short support bars are positioned at the corner place of main frame, and two struts of drawing money on credit are positioned at the vinyl tube centre position on two length directions of main frame.
Further, the length of described main frame is 4m, and width is 3m.
Further, the length of described foam plastic float is 40cm, and width is 30cm, is highly 30cm.
Further, described incubation bag is sewn into the waterproof plastic cloth of 2-3mm the incubation bag that length, width and height are 4m × 3m × 1m, select in the both sides of incubation bag the 150 mesh sieve tulles of 1m × 1m to be used for current respectively to exchange, hook is set in incubation bag upper edge portion and is convenient to be suspended on main frame.
Further, the height of the short support bar of every root is 0.8m, and the draw money on credit height of strut of every root is 1.5m.
Compared with prior art, the beneficial effects of the utility model are: 1, the utility model is by being provided with sunshade net, can resist heavy rain, strong wind, the sun tan by the sun, ensure that ablen fertilized egg until the normal growth of prelarva opening; 2, the utility model manufacture cheap, quality is light, simple to operate, hatchability of fertile eggs is high, hatching water body identical with seedling water, can not cause Early larval stress, hatchability of fertile eggs is high.
