Abstract

The invention discloses a boat-type solar fish-farming net cage in river, comprising a flow rate regulation device. The flow rate regulation device comprises a flow rate measurement cabin, the inner of the flow rate measurement cabin is provided with a tension spring, a flow rate measurement board, a draw bar, and a plurality of regulation pieces for controlling the opening and closing of the flow rate measurement cabin. One end of the tension spring is fixed on the flow rate measurement cabin, and the other end is connected with the draw bar. The draw bar passes through a draw bar sleeve arranged on the flow rate measurement cabin and is fixedly connected with the flow rate measurement board, and the regulation pieces are arranged on the flow rate measurement cabin in revolving and are movably connected with the draw bar. The net cage of the invention is free of the limitation of the power supply, achieves the illumination, the insect killing and automatic feed of bait by using the solar energy. The net cage can automatically control the flow entering the net cage and ensure the reasonable flow-resisting capability of the fishes in the fish-farming, and is suitable for the normal growth of the fishes. In addition, the net cage can kill the injurious insects when illuminating, thereby protecting the wild fish resources in the rivers and developing the farming production of the wild fishes.

Description

technical field

[0001] The invention relates to fish aquaculture machinery technology, in particular to a river boat-type solar-powered fish culture net cage, which is suitable for cultivating wild special fish in rivers and the like. Background technique

[0002] With the improvement of people's living standards and the improvement of food structure, people's desire to eat wild fish is getting stronger and stronger. As people continue to plunder wild fish in rivers, the annual water volume of wild fish in rivers is gradually increasing. The number of wild fish in the market has decreased, and the individuals have become smaller and smaller, causing the contradiction between supply and demand in the market to become increasingly prominent, resulting in a shortage of wild fish in the market, increasing prices, and increasing demand. This requires us to find a farming method that can not only protect wild fish, but also develop wild fish farming.

[0003] At present, the net ...
