Aquatic animal fertilized ovum in-vitro incubating device

Abstract

The invention discloses an aquatic animal fertilized ovum in-vitro incubating device. The aquatic animal fertilized ovum in-vitro incubating device is characterized by comprising an incubator, a nutrient solution disinfecting device, a circulating device for circulating a nutrient solution in the incubator in the incubating process, a temperature control device for controlling the temperature in the incubator, and a filtering device for separating fertilized ova from the nutrient solution, the filtering device is provided with a wavy first slide groove, a wavy second slide groove and a filterscreen arranged on the first slide groove and the second slide groove, the circulating device is provided with an overflow hole, and the overflow hole is higher than the lowest portion of the filter screen and lower than the highest portion of the filter screen. By simulating the micro flowing water environment in the natural conditions and meanwhile keeping the temperature and cleanliness of thenutrient solution, the aquatic animal fertilized ovum in-vitro incubating survival rate is increased.

Description

technical field [0001] The invention relates to a hatching device, in particular to an in vitro hatching device for fertilized eggs of aquatic animals. Background technique [0002] Among the important traditional economically farmed fish in China, the eggs produced by many kinds of fish are all sticky eggs, such as carp and crucian carp. Traditional hatching of sticky eggs generally adopts hatching on artificial fish nests or debonding hatching. Although the artificial fish nest hatching method is easy to operate, the hatching rate is not high, and a certain amount of fish eggs will be lost. Using the debonding hatching method, although the hatching rate has been improved, the debonding of fish eggs is a tricky job, especially in the case of a large number of fish eggs debonding, and it has high requirements for operators. , has certain damage to fish eggs. Contents of the invention [0003] In order to overcome the deficiencies of the prior art, the present invention ...
