Description

Australia freshwater lobster bionic incubation device

Technical Field

The utility model relates to an aquaculture technical field, in particular to bionic hatching apparatus of Australia freshwater lobster.

Background

Australia freshwater lobster (Cherax aquaticarinatus) is one of the most famous and expensive freshwater economic lobster species in the world at present. The shrimp body is brown green, and the outer side of the big crayfish of the mature male shrimp is bright red, so the shrimp is also named as the red crayfish. The reproduction habit of the Australia freshwater lobster is that eggs are taken in vitro, and fertilized eggs are frequently shaken in the egg taking process, so that fresh water flows through the fertilized eggs to be beneficial to normal development of the fertilized eggs, and the Australia freshwater lobster can be directly put into a pond for culture after a parent is hatched into young shrimps.

The Australia crayfish has a small egg holding amount and can swim in the egg holding process, fertilized eggs are easy to fall off or collide and damage, the hatching rate of the fertilized eggs is seriously influenced, meanwhile, once the egg-holding crayfish dies, the crayfish eggs are difficult to develop smoothly, a large amount of crayfish eggs are wasted, the seed supply is often insufficient due to the reasons, and the development of the Australia crayfish industry is seriously restricted.

CN105557590A discloses an in vitro hatching method for australian crayfish, which comprises the steps of obtaining fertilized eggs, cleaning the fertilized eggs, and placing the fertilized eggs into an in vitro hatching tray for artificial hatching. The in vitro hatching tray is provided with a preposed filter barrel, an ozone disinfection machine, a heating tube, an aerator and an isolation net which are matched with a water body, fertilized eggs are placed on the isolation net, bubble stones are arranged at the bottom of the in vitro hatching tray to produce water flow, the fertilized eggs keep slight movement, the ozone machine controls the regular disinfection by time system, and the fertilized eggs can be hatched into the shrimps after being hatched for about 40-50 days. The method adopts the air bubble stone to produce water flow, still has a fixed water circulation, and is still greatly different from the natural incubation state of the Australia crayfish, and secondly, the method mainly depends on producing ozone for disinfection to improve the incubation rate, the artificial intervention is too obvious, and the whole method has low bionic degree.
