Dead fish salvaging device for large yellow croaker enclosure breeding facility

Abstract

The invention relates to the technical field of salvaging equipment, in particular to a dead fish salvaging device for a large yellow croaker enclosure breeding facility. The dead fish salvaging device comprises a fish storage box, transverse rods and a fish-sucking bucket, wherein a vacuum pump is arranged at one end of a pressure valve; one end of the vacuum pump is connected to an exhaust pipe;a fish inlet is formed in one end of the fish storage box; a fish discharge port is formed in the other end of the fish storage box; a fish storage cavity is formed in the inner end of the fish storage box; a grating is arranged at the bottom of the fish storage cavity; a sundries storage tray is arranged at the bottom end of the grating; an underwater camera and an underwater loudspeaker are arranged on the inner wall of the fish-sucking bucket; a control module is arranged on the inner wall of the fish-sucking bucket and is located at one end of the underwater loudspeaker; an antibacteriallayer is arranged at the inner layer of the fish-sucking bucket; a buffering reinforcement layer is arranged at the bottom end of the antibacterial layer; a waterproof layer is arranged at one end ofthe buffering reinforcement layer; and the vacuum pump and the fish storage box are arranged to avoid the low efficiency of manual salvaging, so that the equipment is relatively efficient in use.

Description

technical field [0001] The invention relates to the technical field of fishing equipment, in particular to a dead fish fishing device used in large yellow croaker fence breeding facilities. Background technique [0002] Large yellow croaker (Pseudosicaena crocea), commonly known as yellow croaker, cucumber fish, yellow croaker, etc., is a famous high-value economic fish with tender and delicious meat, high protein, low cholesterol, rich in EPA, DHA and other highly unsaturated fatty acids. Facility breeding of large yellow croaker is a large-scale, intensive and high-efficiency breeding model. The area of ​​the water body in the fence can reach tens of thousands of square meters, and there is a large space for breeding activities. The large yellow croaker cultivated is slender, bright in color, tight in muscle, and of obviously superior quality In ordinary cages and deep-water cages, the meat quality is comparable to that of wild large yellow croakers. [0003] The large ye...

AI Technical Summary

Problems solved by technology

[0003] The large yellow croaker breeding fence is an engineered breeding facility, and the breeding platform is more than 10 meters away from the horizontal. At present, the garbage floating objects and dead fish in the fence are usually salvaged by manual fishing nets. This method is relatively cumbersome to operate and relies entirely on manual labor. Operation, time-consuming and labor-intensive, resulting in low fishing efficiency, and sometimes frightened or accidentally caught normal fish, so a dead fish fishing device for large yellow croaker pen culture facilities is needed to change the status quo
