Description

Technical Field

[0001] The utility model relates to the technical field of fish sperm inactivation, in particular to a large yellow croaker sperm inactivation device. Background Art

[0002] In the process of fish gynogenesis induction, homologous or heterologous sperm only acts as a stimulus source and does not combine with sperm and egg, so homologous or heterologous sperm needs to be inactivated. In the sperm inactivation operation, the sperm is generally inactivated by ultraviolet light in a relatively closed box.

[0003] The Chinese utility model patent (CN213784861U) discloses a highly efficient sperm inactivation device for bream, comprising a body of the sperm inactivation device for bream, a chassis, a box, a square container, a scale, a power switch button, a working indicator light, a power socket, a rotating shaft, a flip cover, a slot and an ultraviolet lamp. The sperm inactivation device for bream is provided with a chassis on the body, a box is provided on the chassis, a square container is placed at the bottom of the box, a scale is engraved on the inner wall of the square container, a power switch button is provided at the lower right corner of the front end of the box, a power socket is provided at the back of the box, a flip cover is provided on the rotating shaft, a slot is provided at the front end of the top of the flip cover, and an ultraviolet lamp is provided in the flip cover. The above device utilizes the ultraviolet height and intensity under certain conditions to completely inactivate the sperm of bream; its disadvantage is that due to the surface tension of the sperm diluent, the diluent cannot be truly spread in the culture dish, and the chassis cannot be completely placed horizontally under the ultraviolet lamp, which will cause uneven sperm inactivation and affect the final test effect.
