Hatching device of adhesive sinking fish eggs and use method of hatching device

Abstract

The invention provides a hatching device of adhesive sinking fish eggs and a use method of the hatching device. The hatching device comprises a water pool, wherein the water pool communicates with a plurality of hatchers through a water supply pipe; a water pump is arranged on the water supply pipe; each hatcher comprises a casing and a hatching sieve arranged in the casing; air stone is arrangedin the casing and is connected with an air supply mechanism through an air pipe; a regulating valve is arranged on the air pipe; and the air stone is arranged under the hatching sieve. The device andthe method have the advantages that the fish egg accumulation is avoided; and the efficient hatching of the adhesive sinking fish eggs can be realized.

Description

technical field [0001] The invention relates to the field of hatching sticky fish eggs, in particular to a hatching device for sticky fish eggs and a method for using the same. Background technique [0002] Since the 1980s, my country's aquaculture industry has been developing vigorously. The eggs of nearly half of the aquatic fish are sticky eggs, and the annual market demand for fry is very large. At present, the artificial incubation of sticky fish eggs mainly uses traditional equipment, such as hatching tanks, which mainly rely on water flow and timing vibration of the hatching tank or manual sieving. The obvious disadvantage of traditional equipment is that the water demand is too large, and there is a certain probability of fish egg damage caused by human factors. [0003] In recent years, some small-scale circulating water system hatching equipment has appeared. The main hatching equipment is conical glassware or spherical glassware. Although these devices reduce th...

The obvious disadvantage of traditional equipment is that the water demand is too large, and there is a certain probability of fish egg damage caused by human factors

Although these devices reduce the water usage rate and reduce the intensity of manual operation, but because the hatching area at the bottom of the glass vessel is too small, the water flow speed of the water pipe at the bottom is not easy to control. Eggs are damaged by violent collision
