Feeding and excrement collection system for fish cage culture

Abstract

The invention relates to the technical field of fish net cage culture, in particular to a feeding and feces collection system for fish net cage culture, which includes a rectangular net cage and a floating support, and also includes a feeding mechanism and a feces collection mechanism. The floating support is horizontal Set, the net cage is horizontally set under the floating support, the feeding mechanism includes a horizontal rotation assembly and a stirring feeding assembly, the feces collection mechanism includes a bottom winding collection assembly and a retrieving assembly, and the bottom winding collection assembly is located at the bottom open end of the net cage , the bottom winding collection assembly includes the first mesh cloth that is attached to the open end of the bottom of the net cage, the first mesh cloth can be horizontally moved and arranged under the net cage, and the retrieving assembly is located on the top of the floating support away from the end of the horizontal rotation assembly , The retrieving component is equipped with a retrieving box that can move to one end of the bottom winding collection component. This equipment can automatically and evenly feed materials, reduce labor intensity, and can collect feces from the net cage from time to time to improve water quality.

Description

technical field [0001] The invention relates to the technical field of fish cage culture, in particular to a feeding and excrement collection system for fish cage culture. Background technique [0002] Pseudomonas is a genus of fish of the genus Siluriformes, Pseudoidae, commonly known as: oxtail, English name: Bullhead, slender body, nearly straight dorsal fin, flat head, flat tail, this genus of fish is in There are about fifteen species in my country, with little difference in body size. They are mostly distributed in various water systems south of the Yangtze River. The individuals are not large, but widely distributed and large in number. They are common small edible fishes. The same species, at present, most of the breeding of catfish at home and abroad is carried out artificially in cages. During artificial breeding, it is usually artificially fed from time to time, which is labor-intensive and uneven in feeding, and the density of cage culture is high. , the high produ...

[0002] Pseudomonas is a genus of fish of the genus Siluriformes, Pseudoidae, commonly known as: oxtail, English name: Bullhead, slender body, nearly straight dorsal fin, flat head, flat tail, this genus of fish is in There are about fifteen species in my country, with little difference in body size. They are mostly distributed in various water systems south of the Yangtze River. The individuals are not large, but widely distributed and large in number. They are common small edible fishes. The same species, at present, most of the breeding of catfish at home and abroad is carried out artificially in cages. During artificial breeding, it is usually artificially fed from time to time, which is labor-intensive and uneven in feeding, and the density of cage culture is high. , the high production of fish feces in a single cage will lead to a decrease in the oxygen content of the local water body and affect the survival rate. At the same time, if the feces cannot be cleaned, it will cause eutrophication in the local water body. Use feeding and manure collection system to solve the problems raised above
