Overwintering culture device of Japanese yellow croaker

Abstract

The invention discloses a Japanese croaker overwintering culture device, and aims to provide a method that can effectively solve the problem that the Japanese croaker indoor culture pond needs to frequently remove residual bait, dead fish and other sundries at the bottom of the pond, which will increase the The energy consumption of the heating device of the large indoor breeding pond, and the Japanese yellow croaker's overwintering culture device that is likely to cause the problem that the water temperature of the indoor breeding pond will fluctuate. It includes a floating culture cage; a sewage pipe; a fixed taper sleeve, the upper edge of the fixed taper sleeve extends upward to form a vertical guide sleeve, and the lower end of the fixed taper sleeve is connected with the sewage pipe through a vertical valve sleeve; the circulation pipe, the circulation pipe One end of one end is connected with the valve sleeve interface, and the other end extends into the floating culture net cage, and a water pump is also provided on the circulation pipeline; a piston assembly, the piston assembly includes an upper piston and a lower piston that are slidably arranged in the vertical valve sleeve; The floating spacer is set on the vertical guide sleeve; the air bag is connected with the floating spacer.

Description

technical field [0001] The invention relates to a culture device for Japanese croaker, in particular to a wintering culture device for Japanese croaker. Background technique [0002] The Japanese yellow croaker is a carnivorous fish belonging to the genus Scrotoaceae and the genus Yellow croaker. The suitable living water temperature is 6-32 ℃. Meager generally needs to be moved into indoor breeding ponds in winter, and heating devices are generally arranged in the indoor breeding ponds to ensure the water temperature of the indoor breeding ponds. [0003] As the Japanese croaker is a carnivorous fish, the bottom of the indoor breeding pond is easy to gather debris such as residual bait and dead fish, so it is necessary to frequently remove debris such as residual bait and dead fish at the bottom of the pool to ensure fresh water quality. In the process of removing debris such as residual bait and dead fish at the bottom of the pool, part of the water in the indoor aquacult...
