Problems solved by technology

[0003] During the hatching and cultivation of fry, it is necessary to maintain the fluidity of the water body. On the one hand, the static water body causes the fry to gather and cause friction and collision between the fry, reducing the survival rate of the fry. On the other hand, the lack of dissolved oxygen in the still water body causes the fry to growth retardation, or even suffocation, at present, the commonly used fish hatching and cultivating devices are mostly hatching loops, which have the following shortcomings: (1) although the water body can have certain fluidity, in order to realize the water body flow, the water consumption is large and the cost is high. (2) When dead eggs and fry appear in the ring road, they cannot be cleaned up in time, causing the spread of saprolegniasis, thereby affecting healthy fry; (3) The timing of feeding eggs in each hatching tank is different, and they should be hatched in the hatching tank as early as possible. The fish roe demembrane early, and the egg membrane dissolving enzyme released into the water enters the hatching tank of the rear fish eggs with the circulating water, which will cause the fish roe put into the hatching tank to demembrane early, and the early demembrane mostly occurs in the caudal fin of the embryonic development During the period from emergence to muscle effect stage, the egg membrane ruptures or dissolves, and the embryo body without the protection of the egg membrane sinks to the bottom of the water and dies

Abstract

The invention relates to the technical field of fry hatching, in particular to a tilapia mossambica roe hatching circulation system. The system comprises a rack, a hatching pond, a temporary raising pond, a fry pond, hatching barrels, a temporary raising basin, a water storage pond and a water supply pond. By forming a hatching cavity, each hatching barrel can be cultured independently to preventdifferent roe feeding times of the hatching barrel. Egg envelope lytic enzymes released by roes without membranes input into the hatching barrel early to water enter the hatching barrel along with circulating water and roes are put in the hatching barrel to lead to membrane release of roes put in the hatching pond, so that the hatching rate is reduced; the content of dissolved oxygen in water is improved through water circulation, so that the hatching rate is prevented from being reduced as a result of oxygen deficit in the hatching process. The dosage of water can be reduced, so that the system is energy-saving and environment-friendly. By arranging the hatching barrels, the temporary raising basin and the fry pond on the rack to form a three-layered three-dimensional structure, an intactfry hatching culture process can be finished, so that the intermediate transfer links are reduced, the hatching efficiency is improved and the production cost is lowered.

Description

technical field [0001] The invention relates to the technical field of fry hatching, in particular to a tilapia roe hatching circulation system. Background technique [0002] The hatching process of fry: fertilized eggs - larvae - fry. The fertilized eggs need to be placed in the hatching bucket for incubation. After hatching, they are transferred to the temporary culture basin for cultivation. The larvae mainly rely on the yolk for nutrition. After absorbing from the yolk sac, they develop to have Until a certain number of fin rays are transferred to the fry pond for feeding. [0003] During the hatching and cultivation of fry, it is necessary to maintain the fluidity of the water body. On the one hand, the static water body causes the fry to gather and cause friction and collision between the fry, reducing the survival rate of the fry. On the other hand, the lack of dissolved oxygen in the still water body causes the fry to growth retardation, or even suffocation, at pres...
