Artificial incubation equipment for viscid fertilized eggs of fishes

Abstract

The invention discloses artificial incubation equipment for viscid fertilized eggs of fishes and belongs to the field of fish farming. The artificial incubation equipment comprises an inverted-cone shell, a cone-frustum-shaped loop, a net bag, a circular top cover, a main body support and a water inlet and outlet system. The artificial incubation equipment for the viscid fertilized eggs of the fishes has the advantages that the structure with the inverted-cone shell sleeving an inverted-cone net is adopted creatively, a gap is reserved between the inverted-cone shell and the inner inverted-cone net, wall attachment and caking can be effectively avoided with the help of bottom ascending water flow, and the inverted-cone net is capable of effectively dispersing water flow to prevent the water flow from impacting the fish eggs, so that a fish egg incubation rate can be increased; internal clearing of the incubation equipment is facilitated through the detachable bottom cone net bag; with a ringlike water pipe clearing system, the artificial incubation equipment is capable of effectively clearing mildewed embryos during incubation to greatly avoid adverse effect of excessive anthropogenic interference on egg incubation; the artificial incubation equipment is low in manufacturing cost, simple and convenient to operate and particularly suitable for large-scale factory-like breeding application in the field.

Description

technical field [0001] The invention belongs to the field of fish breeding, in particular to an artificial hatching device for fish viscous fertilized eggs. [0002] technical background [0003] With the rapid development of the fish farming industry, the supply of fish fry has gradually shifted to the stage of artificial breeding. In the artificial hatching of fish eggs, people often use corresponding hatching facilities and methods according to different ecological types of fish eggs to improve the hatching rate of fertilized eggs and ensure the smooth progress of fish seed breeding. Sticky eggs are one of the ecological types of fish eggs. The specific gravity of the eggs is higher than that of water. The outer layer of the egg membrane has sticky substances, which can adhere to the surrounding aquatic plants and other objects during incubation without sinking to the bottom. Among them, freshwater fish and seawater fish Fish eggs such as carp, crucian carp, group head br...
