Description

Technical Field

[0001] The invention relates to the technical field of aquaculture, in particular to an equipment system for hatching red claw crayfish larvae into blackheads. Background Art

[0002] Shrimp fry refers to the small shrimp obtained after hatching, usually only a few millimeters to a few centimeters long. It is the initial stage of shrimp growth. It is divided into marine shrimp fry and freshwater shrimp fry, which are adapted to different water environments. A large number of high-quality and healthy shrimp fry can be obtained through artificial cultivation and used in aquaculture to increase shrimp production and quality.

[0003] The existing equipment system for hatching red claw crayfish larvae to blackheads has a low seed density, making it difficult to intensively manage and scale up. The cultivation system is large in size, consumes a lot of nutrients, and cannot achieve low-cost seed nutrition fortification. Summary of the invention

[0004] The invention aims to provide an intensive equipment system for hatching red claw crayfish larvae into blackheads.

[0005] To achieve the above objectives, the technical solution of the present invention is as follows.

[0006] The equipment system for hatching red claw crayfish larvae into blackheads, the larvae culture tank, extends along the length direction of the equipment system. The hanging rope, extending along the length direction, is arranged in the larvae culture tank and is located on the upper side of the water body of the larvae culture tank, and is used to hang the red claw crayfish larvae.

[0007] The hanging rope suspends the red claw crayfish larvae through the rope body; the rope body comprises a fiber body for hanging the red claw crayfish larvae, and the red claw crayfish larvae are hung on the rope body through the hook of the tail hook and the hook of the fiber body.

[0008] It can be seen that by centrally hanging the red claw crayfish larvae in the larval culture tank for cultivation, intensive management and large-scale cultivation of red claw crayfish larvae can be achieved. The water volume in the larval culture tank is controlled and extremely limited, which is conducive to reducing the amount of nutrient solution in the water, facilitating low-cost nutritional fortification, and improving the immunity and stress resistance of red claw crayfish larvae at a low cost, which is conducive to large-scale cultivation.

[0009] Furthermore, the oxygenating device is used to add oxygen to the water body. The filtering device is used to circulate and filter the water body, which is beneficial to increase the oxygen content of the water body and reduce the turbidity of the water body.

[0010] Furthermore, an insulated room is used to enclose the larval culture tank. A constant temperature device is used to adjust the water temperature.

[0011] Furthermore, the thermostatic device is an air conditioner or a water heater.

[0012] Further, the water supply port of the filter device is located at the first end of the larval culture tank. A drain pipe extending in the height direction is provided at the second end of the larval culture tank opposite to the first end, an overflow port is provided on the upper side of the drain pipe, and the lower end of the drain pipe is detachably sleeved on the drain port of the larval culture tank. The water return port of the filter device is connected to the drain port.

[0013] Furthermore, the water return tank is used to receive the water discharged from the drain port. The water return port is connected to the discharge port of the water return tank.

[0014] Furthermore, the filtering device has a sedimentation tank, which includes a primary sedimentation tank, a secondary sedimentation tank, and an overflow pipe arranged between the primary sedimentation tank and the secondary sedimentation tank. A filter screen is arranged in the overflow pipe.

[0015] Furthermore, the filtration device includes a water pump, the water inlet of the water pump is connected to the final sedimentation tank, and the water outlet of the water pump is connected to the water supply port. The oxygenation device includes an oxygenator, an air pipe and a nano oxygenation tube, which extends in the length direction and is arranged on one side of the larval culture tank close to the first end.

[0016] The oxygen supply device also includes an auxiliary oxygen supply pipe, which is connected to the trachea through a valve. The auxiliary oxygen supply pipe is arranged on one side of the larvae culture tank close to the second end.

[0017] Methods for hatching red claw crayfish larvae into blackheads: Prepare any of the aforementioned equipment systems for hatching red claw crayfish larvae into blackheads.

[0018] Red claw crayfish larvae ready to rupture their membranes and grow a tail hook.

[0019] The tail hook is hooked to the rope body to hang the red claw crayfish larvae on the rope body.

[0020] The rope body is hung on the hanging rope for breeding until the red claw crayfish larvae grow to the black head state.

[0021] It can be seen that using ropes to hang red claw crayfish larvae and limit their range of activities is conducive to intensive management and large-scale cultivation. The water volume in the larval culture tank is controlled and extremely limited, which is conducive to reducing the amount of nutrient solution in the water, facilitating low-cost nutritional fortification, and improving the immunity and stress resistance of red claw crayfish larvae at a low cost, which is conducive to large-scale cultivation.

[0022] Furthermore, the rearing time from the hatching of red claw crayfish larvae to blackhead is 9 to 15 days, and the rearing temperature is 25 to 28°C. BRIEF DESCRIPTION OF THE DRAWINGS
