Abstract
The invention provides a power-driven air-pressure egg taking device for fish artificial reproduction, and relates to an egg taking device used in the fish artificial reproduction process. The power-driven air-pressure egg taking device aims to solve the problems that in an existing fish artificial reproduction process, stronger strength of hands is needed to squeeze the abdomen, the technical levels of operators are different, the parent fish is damaged easily when the abdomen is squeezed, and death is caused; the number of the large-scale produced parent fish is large, the labor intensity is high, and the working efficiency is low. According to the power-driven air-pressure egg taking device, a power-driven air inflation pump and an air inflation bag are utilized to inflate and squeeze the abdomen of a fish body, so that an original artificial manual operation is changed to mechanical operation of the power-driven air inflation bag in the female parent fish egg taking process, the labor intensity is lowered greatly, and the working efficiency is improved by 75% compared with the traditional method; through appropriate control of a airflow control valve and an air pressure gauge, the operation process of egg squeezing through the air inflation bag is made to be more stable and even, harm to the fish body is lower, and the death rate of the female parent fish reproduction is reduced by 50% compared with the traditional method. The power-driven air-pressure egg taking device is suitable for being used in the fish artificial reproduction process.
