Aquatic animal fertilized ovum in-vitro incubation device

Abstract

The invention discloses an aquatic animal fertilized ovum in-vitro incubation device. The aquatic animal fertilized ovum in-vitro incubation device is characterized by comprising a water tank, wherein columnar sponges are arranged inside the water tank, a plurality of grooves are evenly formed in the outer side walls of the columnar sponges, central water adsorption tubes are inserted into the center of the columnar sponges, a plurality of small holes are evenly formed in each central water adsorption tube, a drain pipe with a valve is arranged at the tail end of the central water adsorption tube through a submerged pump, the outlet end of the drain pipe is communicated with an external filter which is provided with a plurality of layers of filter cotton in a placement mode, the external filter is also communicated with the water tank through a drain pipeline, the columnar sponges and the central water adsorption tubes are matched with each other, the number of the columnar sponges and the number of the central water adsorption tubes is multiple, the tail end of each central water adsorption tube is connected with the drain pipe through the submerged pump, a temperature control heater is further arranged in the water tank, and a plurality of horizontal grooves are further formed in the grooves. The aquatic animal fertilized ovum in-vitro incubation device can imitate a slight water running environment in natural conditions, and can keep an incubation water body to be clean and keep the environment to be stable.

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] Studying the embryonic development process and influencing factors of aquatic animals not only has scientific significance, but also helps to grasp the corresponding technical links in seed production. However, for some aquatic animals, such as shrimps and crabs with ovipositing habits, it is difficult to obtain fertilized eggs; or accidental death of broodstock during the sampling process will hinder subsequent research. Even for some species that directly lay their eggs in water, such as most fishes, the hatching of their fertilized eggs under experimental conditions is often harmed by saprolegnia, protozoa, etc., resulting in hatching failure. Because of these problems, it is more difficult to study the influence of environmental factors such as water temperature and salinity on the developme...

AI Technical Summary

Problems solved by technology

Frequent sampling can easily disturb the parent body, and even lead to the abandonment of eggs, which not only delays research, but also wastes the opportunity of seed breeding, affecting the protection of rare species

In addition, when shrimps and crabs are artificially bred, the phenomenon of death after breeding broodstock occurs from time to time, which will seriously hinder the breeding process
