Description
Technical Field
The invention relates to the technical field of aquatic product incubation, in particular to a combinable spiral core for fish egg incubation and an incubation device.
Background
The common cultured fish has various types of fish eggs, one is semi-floating egg, the egg membrane absorbs water and expands, and the fish is suitable for flowing water and is like egg granules of herring, grass carp, silver carp, bighead carp, silver catfish and other fishes; the other is a viscous egg which is suitable for sprinkling water for hatching, and if the viscous egg is hatched by using running water, the viscous egg is subjected to 'debonding' treatment, such as carp, crucian carp, bream, xenocypris davidi bleeker, plagiognathops microlepis and the like. And present stickness roe generally can adopt the roe supporting body to bear the weight of roe when hatching, for example the dictyosome, brush body isotructure, nevertheless the roe breaks away from the roe supporting body easily and removes when the flowing water hatching, and the trickle hatching also has the problem of downstream, so how to guarantee that the roe is difficult to fall from the roe supporting body is a problem that awaits the solution urgently.
Based on the scientific research advantages of the subject group, experimental research is carried out in related fishery bases, and the problem that not only is the situation that viscous roe is well borne by a roe bearing body solved, but also how to efficiently increase the roe bearing body according to the hatching amount requirement is solved, so that a combinable spiral core and a related hatching device which can be combined to increase and decrease a spiral sheet according to the requirement are specially designed, and the prior art which is the closest to Chinese patent with the patent application number of '2019104504734' and the patent name of 'a viscous roe hatching device' is found after retrieval.
Chinese patent with patent application number '2019104504734' and patent name 'a stickness roe hatching apparatus' discloses a stickness roe hatching apparatus, the hatching apparatus includes the incubator, the top of the incubator is provided with the sealed lid, the bottom of the incubator is provided with the delivery port; the viscous fish egg hatching device also comprises a spraying device, a support device and a plurality of fish egg loading devices which are respectively arranged in the incubator, wherein the support device comprises a central shaft and a plurality of hanging supports, the central shaft is vertically arranged, and the hanging supports are radially arranged at the periphery of the central shaft at intervals; the hanging bracket is used for hanging the fish egg loading device; the spraying device is used for spraying water mist to the fish egg loading device, the viscous fish egg hatching device is used for suspending the fish egg loading device through the support device, each fish egg loading device is suspended separately, the problem that fish eggs are overlapped and pressed to lack oxygen can be effectively avoided, and the fish egg hatching rate is improved. However, the fish egg loading device is only a hanging net which is vertical and has limited bearing capacity, fish eggs are easy to slide down under the action of dead weight and water flow after being poured, and the fish eggs are easy to wash off the hanging net when being hatched by running water, which is a problem which is not solved at present and is also a problem to be solved by the invention.
