Water-saving fish egg incubating device

Abstract

The invention discloses a water-saving fish egg incubating device which comprises a water tank, an overflow pipe, an incubator and a water inlet pipe, wherein the water tank and the water inlet form a high-level water source treatment tank; water flow overflows from the overflow pipe after being full; the upper part of the water inlet pipe is connected with the incubator through a metal opening; the front end of the overflow pipe is connected with the water tank; the rear part of the overflow pipe is connected with a filter; the upper part of the filter is connected with the overflow pipe; the lower part of the filter is connected with an adjustable speed water pump through a water pipe; the front side of the adjustable speed water pump is connected with a miniature air conditioner; the rear part of the adjustable speed water pump is connected with an aerator; the left side of the adjustable speed water pump is connected with the filter through the water pipe; the rear part of the miniature air conditioner is connected with the adjustable speed water pump; the front part of the adjustable speed water pump is connected with the water inlet pipe; a circulating water adjusting valve is arranged on the water inlet pipe; the upper part of the water inlet pipe is connected with the incubator through the metal opening; the left side of the water inlet pipe is connected with a germinating branch pipe; a seedling collecting valve is arranged on the germinating branch pipe; the front end of the germinating branch pipe is connected with the water inlet pipe; and the rear end of the germinating branch pipe is connected with a seedling collecting tank.

Description

technical field [0001] The invention belongs to the field of aquaculture equipment, in particular to a water-saving fish egg artificial hatching device. Background technique [0002] The hatching rate of fish species determines the number of larvae. With the continuous development of aquaculture industry, the demand for artificial hatching of fish eggs is increasing. Therefore, fish egg hatching technology is one of the key technologies in large-scale fry breeding technology. First, the high-performance fish egg hatching device is an important guarantee for improving the hatching rate of fish eggs. [0003] The fertilized eggs of most cultured fish in my country are sinking eggs. When sinking fish eggs are hatched artificially, the factors that affect the hatching of fish eggs are ammonia, nitrogen, oxygen, water temperature and pH value. During the hatching process, the oxygen consumption is high, the PH value of the water does not change much, and the ammonia and nitroge...

AI Technical Summary

Problems solved by technology

[0004] At present, the commonly used facilities for the incubation of sinking fish eggs include hatching rings, hatching tanks, hatching buckets, hatching tanks, etc. The disadvantages of the above-mentioned devices are that they occupy a large area and the cost of equipment is high; the water consumption is large, and the water flow speed is not easy to control. The water exchange surface area is small, and the water treatment facilities can't keep up, which will lead to insufficient oxygen supply and deterioration of water quality; the quality and temperature of hatching water are greatly affected by the quality of water source and weather conditions, which will affect the development of fish egg embryos, and even develop deformity or death. Thus causing Saprolegnia infestation; at present, relying on drugs to inhibit Saprolegnia is one of the most important measures to improve the hatching rate of fish eggs
