Sticky fish egg hatching device

Abstract

The embodiment of the invention discloses a sticky fish egg hatching device, and relates to the field of aquaculture equipment. The hatching device comprises a hatching box, wherein the top of the hatching box is provided with a sealing cover; a water outlet is formed in the bottom of the hatching box; the sticky egg hatching device also comprises a spraying device, a support frame device and a plurality of fish egg loading devices; the spraying device, the support frame device and the plurality of fish egg loading devices are respectively arranged in the sticky fish egg hatching box; the support frame device comprises a center shaft and a plurality of hanging support frames; the center shaft is in vertical arrangement; the plurality of hanging support frames are radially arranged at the periphery of the center shaft at intervals; the hanging support frames are used for hanging the fish egg loading devices; the spraying device is used for spraying water mist on the fish egg loading devices. The sticky fish egg hatching device provided by the embodiment has the advantages that the fish egg loading devices are hung through the support frame device; each fish egg loading device is hung in a separated way; the problem of oxygen deficiency due to fish egg overlying can be effectively solved; the fish egg hatching rate is improved. Through the arrangement of a temperature control system, the fish egg hatching temperature and humidity can be effectively controlled; the fish egg hatching rate is further improved.

Description

technical field [0001] The embodiment of the present invention relates to the field of aquaculture equipment, in particular to a viscous fish egg hatching device. Background technique [0002] At present, for the hatching of sticky fish eggs, methods such as hatching in still water in ponds, flowing water hatching and water spraying hatching are usually adopted. The hatching of viscous fish eggs in still water or running water in ponds is easily affected by external weather conditions such as heavy rain, cold waves, etc., and is also susceptible to saprolegniasis. In addition, the length of hatching time is not easy to control with changes in water temperature, resulting in low hatching rates of fish eggs. The cycle is long, which seriously reduces the work efficiency and economic benefits of farmers. [0003] In the prior art, the water-spraying hatching method has been tried to solve the above problems in the pond hatching, but the existing water-spraying hatching method ...
