Problems solved by technology

However, there are still some key technical problems to be solved when using submersible cages to culture flounder and flounder. First, there are difficulties in the floating and sinking operations of the cages; Small, it cannot be restored after being deformed in seawater, resulting in deformation of the bottom of the net, which is not conducive to the habitat of flounder fish. major economic loss
At present, the lifting net cages all have a rigid structure net cage frame, which requires more supporting equipment, and the structure of the mooring system is complicated and the cost is high

Abstract

The present invention relates a rope-type sea-water culture net cage which can be conveniently lifted upwards and fallen downwards. It includes the following several portions: net cage frame system consisting of main floats, rope frame, marker float and marker float rope; net bag system composed of net bag, bottom frame and sinker; and gappling system formed from grapnel and rope. Besides, said invention also includes a net cage lifting and falling control system formed from control float, control float rope and control sinker.

Description

technical field [0001] The invention belongs to aquaculture equipment, and in particular relates to a rope-type seawater culture net cage which is convenient for lifting. Background technique [0002] The use of net cages to culture flounder and flounder in the natural open seas of the north can greatly reduce the cost of breeding on the one hand, and on the other hand can reduce the use of farming chemicals and improve the quality of the breeding objects, thereby increasing the value of the cultured species. However, using net cages to breed flounder and flounder fish requires a relatively stable environment at the bottom of the cages for the cultured objects. If floating cages are used for farming, the wind and waves on the ocean surface will inevitably lead to large-scale swings in the cages, which cannot be guaranteed. The bottom of the net cage has been in a stable state, causing friction between the cultured objects and the bottom of the net, resulting in fish damage, ...
