Incubation device for clustered eggs of aquatic product

Abstract

The invention relates to an incubation device for clustered eggs of an aquatic product. The incubation device is characterized in that the incubation device comprises a water tank, a rotating shaft is arranged above the two ends of the water tank and is fixedly provided with at least one water stirring paddle wheel, the rotating shaft is driven by a motor, the water stirring paddle wheel rotates along with the rotating shaft to stir the water in the water tank, a water inlet is arranged at the left end of the water tank, a water outlet is arranged at the lower part of the right end of the water tank, the water tank is internally provided with a horizontal support rod which is used for placing a net cage where clustered eggs are contained, a horizontal guiderail is further arranged at the upper part of the water tank, a water pushing trolley is arranged on the guiderail and is fixedly provided with at least one pair of water scraping rods vertically extending into the water tank below, the water scraping rods are located between the side wall and the net cage, a water scraping plate is connected between the pair of water scarping rods and is lower than the support rod, a row of water guide pipes are arranged at each of the two sides of the water scraping plate, one side of each water guide plate, which is close to the water scraping plate, is upwards slant, and the other side of each water guide plate is downwards slant. According to the incubation device, the incubation success rate of the clustered eggs of the aquatic product is greatly improved, and the incubation density and the yield of fish fries are high.

Description

Technical field [0001] The invention relates to an aquaculture device, in particular to an aquatic mass egg hatching device, belonging to the technical field of aquaculture. Background technique [0002] At present, the artificial incubation of aquaculture such as aquaculture generally adopts the method of loop or incubation barrel. However, these two types of incubation facilities are not ideal for the incubation of massive eggs. The incubation loop is generally built outdoors, with a large site and high construction cost, which is not suitable for small-scale incubation. In production practice, the use of incubators for incubation, the water flow is not constant, and the egg mass can not be fully contacted, the egg mass is prone to hypoxia, and there are many dead spots in the incubator, resulting in a large part of the egg mass death due to hypoxia, and the hatching rate and hatching density are very low. Summary of the invention [0003] The technical problems that the presen...

Problems solved by technology

[0003] The actual technical problems that need to be solved in the present invention are: the traditional artificial hatching method has a large-scale loop hatching site, high construction cost, and is not suitable for small-scale hatching; the hatching bucket is used for hatching, the water flow is not constant, and the eggs cannot be fully contacted. Eggs are prone to hypoxia, and there are many dead spots in the hatching bucket, resulting in the death of a large part of the eggs due to hypoxia, and the hatching rate and hatching density are very low
