Stain-repellent stretch net cage for farming large yellow croaker

Abstract

A stain-repellent stretch net cage for farming large yellow croaker relates to a cage for mariculture of the large yellow croaker. The stain-repellent stretch net cage for farming large yellow croaker is provided with a floating system and a net system and is characterized in that the floating system is in a rectangular frame structure with double floating pipes, the net system is in a combined structure of a longitudinal cage upper end net, a longitudinal cage lower end net and a cage bottom net; the cage bottom net is fitted on a frame wrapped with a synthetic fiber mesh, and the frame is connected with lower edge horizontal ropes of the longitudinal cage lower end net; after the longitudinal cage lower end net is connected with the cage bottom net, vertical man ropes longitudinally disposed along the longitudinal cage upper end net from upper horizontal ropes of the longitudinal cage upper end net extends to edge ropes of the cage bottom net; crossing man ropes are added to the bottom of the cage, crossing man ropes are added along diagonals of the bottom of the cage, a high-strength polypropylene rope is tied to an intersection of the two crossing man ropes arranged along the diagonals of the bottom of the cage, and a cylindrical foam float is tied to the other end of the high-strength polypropylene rope.

Description

technical field [0001] The invention relates to a net cage for cultivating large yellow croakers at sea. Background technique [0002] Existing large yellow croaker breeding net cage can be divided into square large yellow croaker breeding net cage, circular large yellow croaker breeding net cage according to its frame shape. The synthetic fiber mesh and rope raw materials used in the existing large yellow croaker breeding cages consume a lot of raw materials, and the fouling and adhesion are very serious in the breeding production, resulting in a large number of times for farmers to change the mesh, and the labor intensity of changing the mesh is relatively high. The water exchange is not smooth, which affects the normal growth and development of large yellow croaker and the breeding benefits. During the development of large yellow croaker cages, some problems need to be solved urgently, such as the problem of antifouling of large yellow croaker cages, the problem of energ...

AI Technical Summary

Problems solved by technology

The synthetic fiber mesh and rope raw materials used in the existing large yellow croaker breeding cages consume a lot of raw materials, and the fouling and adhesion are very serious in the breeding production, resulting in a large number of times for farmers to change the mesh, and the labor intensity of changing the mesh is relatively high. The water exchange is not smooth, which affects the normal growth and development of large yellow croakers and the breeding benefits

During the development of large yellow croaker cages, some problems need to be solved urgently, such as the problem of antifouling of large yellow croaker cages, the problem of energy consumption of large yellow croaker cages, the problem of bait utilization coefficient of large yellow croaker cages and the The low problem of box body volume retention rate etc., these problems are technical problems that have not been solved for a long time in this technical field, and processing large yellow croaker breeding cages with stretching nets is also a technical problem that has not been solved for a long time, this area urgently needs to develop a kind of It can be used in stretched net cages for large yellow croaker breeding to ensure that the large yellow croaker breeding cages have better antifouling function, lower energy consumption, higher bait utilization coefficient and box volume retention rate, and improve the quality of large yellow croaker farming. The economic benefits of cages can improve the level of complete facilities and equipment for large yellow croaker breeding cages, promote the sustainable development of large yellow croaker breeding industry, and improve the grade of large yellow croaker industry
