Seawater net cage device capable of preventing attached growth of algae and using method of seawater net cage device

Abstract

The invention belongs to the technical field of marine fishery, and particularly relates to a seawater net cage device capable of preventing attached growth of algae. The seawater net cage device comprises a bracket, wherein a support plate is fixedly connected to the bracket, a rotating shaft is rotatably connected to the support plate, a spherical net cage is fixedly connected to the rotating shaft, a worm is rotatably connected to the bracket, a wind wheel is connected to the worm in a sleeving manner, and a worm wheel is connected to the rotating shaft in a sleeving manner. According to the seawater net cage device disclosed by the invention, wind power in the nature can be used, and the spherical structure of the spherical net cage is used for cooperation, so that in the rotating process of the spherical net cage, netting at all positions of the net cage can receive sunlight, attached algae spores can be effectively irradiated and killed, breeding of the algae spores is avoided, complexity and labor loss of manual cleaning are avoided, the net cage does not need to be taken out for cleaning, and fish culture is not affected.

Description

technical field [0001] The invention belongs to the technical field of marine fishery, and in particular relates to a seawater cage device capable of preventing algae from attaching and growing and a method for using the same. Background technique [0002] At present, for the cultivation of marine fish, the mode of seawater cage culture is generally adopted. Seawater cage culture has the advantages of superior water quality, good quality of fish products, wide sea area, resource saving, flexible maneuvering, convenient management, less investment and high efficiency. . [0003] Since the cages for breeding are placed in seawater for a long time, they are easily attached by some algae plant spores. After a period of time, the algae plants will attach and grow on the cages, thereby increasing the weight of the cages, blocking the mesh, and hindering the smooth flow of water. , affect the exchange of water inside and outside the net cage, increase the pressure of the net, or e...

Problems solved by technology

[0003] Since the cages for breeding are placed in seawater for a long time, they are easily attached by some algae plant spores. After a period of time, the algae plants will attach and grow on the cages, thereby increasing the weight of the cages, blocking the mesh, and hindering the smooth flow of water. , affect the exchange of water inside and outside the net cage, increase the pressure of the net, or even wear the net, scratch the fish body, and affect the growth of the fish. Therefore, it is often necessary to manually remove the net cage and clean it manually. This is more cumbersome, and It is a waste of manpower. In addition, when taking out the cage, the fish in the cage need to be resettled, which will easily frighten the fish and affect the growth of the fish.
