The farming cycle of crayfish is relatively long and the requirements for environmental conditions are relatively strict. Especially in the cultivation stage of crayfish seedlings, the management of seedling stocking is particularly important in order to improve the survival rate and growth rate of crayfish.

[0003] The crayfish larvae that are raised each time are often disinfected before being released to ensure their normal growth. In addition, the crayfish larvae are prone to death in new breeding waters due to the water not being adapted to the new water. The existing patent (publication number: CN215346533U) discloses a transitional pond for stocking crayfish larvae, comprising a transitional holding pond body and a centralized stocking pond structure located at the outer end of the transitional holding pond body. The upper end of the transitional holding pond body is provided with a net cage placement partition, a temporary holding net cage body located within the net cage placement partition, a transitional holding pond body inlet pipe located at the lower part of the transitional holding pond body, and a transitional holding pond body outlet pipe. The centralized stocking pond structure includes a stocking pond body, a stocking gate located at one end of the stocking pond body, and a stocking slope structure located below the stocking gate. The advantages of this utility model are: ensuring the adaptation of crayfish larvae to the water transition, effectively ensuring the disinfection of crayfish during stocking, and being easy to install and disassemble, thus improving the breeding rate and possessing excellent practicality.

[0004] Existing patents offer solutions to the above problems, but they have drawbacks such as difficulty in draining the disinfected lobsters from the transition tank and the inability to fully mix the liquid entering the transition tank with the disinfectant.

[0005] To address this, a transitional device for releasing lobster larvae is proposed. Utility Model Content

[0028] During use, lobster larvae are placed in the net frame 2, and the filter screen 3 prevents the larvae from escaping while allowing water flow. Water thoroughly mixed with disinfectant is injected into the transition tank 1 through the liquid mixing mechanism 5. The oxygen pump 63 delivers air through the loop pipe 61 to multiple oxygenation heads 62, forming a uniform bubble flow at the bottom of the transition tank 1 to meet the high oxygen demand of the lobster larvae. The top cover 9 protects the lobster larvae inside the transition tank 1. The ventilation heads 10 on both sides of the top cover 9 discharge carbon dioxide produced by metabolism in the tank through natural convection, maintaining the oxygen and carbon dioxide balance. When stocking lobsters... The electric push rod 44 drives the plug 45 to descend along the inner wall of the control cup 42. The sealing ring 13 on the side wall of the plug 45 forms a dynamic seal with the control cup 42 and the connector 41 to prevent water leakage. The plug 45 descends to below the stocking inclined tube 43. At this time, the lobsters follow the flowing liquid from the inside of the net frame 2 to the stocking inclined tube 43 and enter the subsequent breeding pond. The liquid inside the transition pond 1 is replaced through the liquid outlet pipe 11 and the plug 12. In this way, it is convenient to release and discharge the lobster seedlings after cleaning and transition, and avoid damage to the lobster seedlings during discharge.
