Problems solved by technology

[0005] People often net shrimp by the river. Shrimp is different from fish and cannot be caught with a hook. Generally, it can only be caught with a net. Generally, a small net is straightened, and a bone or other bait is placed in the middle, and the net is collected after a while. can catch shrimp, but this method of catching shrimp is too inefficient for large-scale shrimping

Embodiment 1

[0026] Such as Figure 1-5 As shown, the lobster catcher with self-resetting net cover includes a breeding box 1, a feeding device 5 is provided above the middle of the breeding box 1, a partition 17 is provided at the bottom of the breeding box 1, and a salt melting device is provided below the partition 17 21. An oxygen outlet pipe 18 is provided below the salt melting device 21, and an oxygen outlet hole 19 is provided on the oxygen outlet pipe 18. Connecting rods 10 are provided on the left and right sides of the breeding box 1, and the top of the connecting rod 10 is connected to the top of the breeding box 1. Several floating beds 11 are arranged on the connecting rod 10, and at least 3 habitat grooves are opened on the surface of the floating beds 11. This breeding box integrates feeding, oxygenation, breeding, and net collection. It has complete functions. It is equipped with a floating bed to reduce the breeding density of the breeding box. There will be lobsters hidd...

Embodiment 2

[0037] Such as Figure 1-5 As shown, when the self-resetting lobster capture device with net cover of the present invention is actually used: put the lobster seedlings that need to be cultured into the device, the lobsters will disperse and hide in the floating bed 11 or the light shield 12, reducing the cost of lobster cultivation. In terms of density, the shading plate 12 can block most of the direct sunlight, and at the same time, the silt layer can provide a layer of camouflage and cover for the lobster, which is closer to ecological breeding. When the bait in the breeding box 1 is insufficient, the feeding device 5 can realize large-area rapid feeding. bait, there will be no phenomenon of lobsters grabbing food and fighting each other. The bottom of the breeding box 1 is provided with an oxygen outlet pipe 18. The oxygen outlet pipe 18 blows out air bubbles in the water, and the air bubbles float up to speed up the melting of oxygen in the water and provide sufficient nutr...

Abstract

The invention provides a lobster trapping device with self-repositioning nets and belongs to the technical field of aquaculture fishing. The device comprises an aquaculture box; a releasing device isinstalled over the middle part of the aquaculture box; a lower part of that inner part of the aquaculture box is provide with a partition plate, a salt melting device is arranged below the partition plate, an oxygen outlet pipe is arranged below the salt melting device, an oxygen outlet hole is arrange on the oxygen outlet pipe, connecting rods are arranged on the left and right sides of the aquaculture box, the top ends of the connecting rods are connected with the top of the aquaculture box, a plurality of floating beds are arranged on the connecting rods, and the surface of the floating beds is provided with at least three inhabiting grooves. The device can culture lobster, has low culture density and fast growth speed, can remove the sludge hidden in the lower part of the abdomen of lobster, can realize automatic net harvesting, has high shrimp catching efficiency, and is suitable for large-scale catching.

Description

technical field [0001] The invention belongs to the technical field of aquatic products fishing, and in particular relates to a lobster catcher with a self-resetting net cover. Background technique [0002] Lobsters are native to Central and South America and northeastern Mexico. The distribution in China has expanded to Anhui, Hubei, Shanghai, Jiangsu, Hong Kong, Taiwan and other places, forming a large number of natural populations. [0003] The head and chest of the lobster are relatively thick, the shell is hard, colorful, the abdomen is short, the body length is generally between 20 and 40 cm, and the weight is about 0.5 kg. It is the largest type of shrimp. The heaviest can reach more than 5 kilograms, known as the lobster tiger. The body is thick and cylindrical, the back and abdomen are slightly flat, the carapace is well developed, thick and spiny, and there is a pair of powerful eye spines in the center of the front edge, with a closed gill chamber. The abdomen ...
