Bird preventing and water-flow preventing floating fish bait feeding device

Abstract

The invention relates to a bird preventing and water-flow preventing floating fish bait feeding device. The bird preventing and water-flow preventing floating fish bait feeding device is characterized in that the device comprises a cylinder body, wherein openings are formed in the two ends of the cylinder body, the upper end opening of the cylinder body is covered by a screen piece, the lower end opening of the cylinder body is maintained open, a plurality of floaters are evenly distributed on the outer wall of the cylinder body, the cylinder body half floats on the water surface through the floating force provided by the floaters, and a part of the upper end of the cylinder body is above the water surface. The bird preventing and water-flow preventing floating fish bait feeding device is simple in structure, easy and convenient to operate, low in manufacturing cost, capable of preventing birds from stealing fodder and preventing the fodder from flowing out of a net cage along with the water flow, capable of effectively avoiding fodder waste in the culturing process and especially suitable for fish culturing in flowing water bodies under fixed point feeding condition.

Description

technical field [0001] The invention relates to a floating fish bait feeding device which prevents birds and water flow, and belongs to the technical field of aquaculture. Background technique [0002] China is a big aquaculture country in the world. Ponds, lakes and reservoirs play an important role in freshwater fishery. Especially since the reform and opening up, my country has implemented the fishery development policy of "focusing on farming", which has enabled aquaculture to develop rapidly. According to the "2012 China Fishery Statistical Yearbook", my country's aquaculture output reached 40.2326 million tons, accounting for 71.8% of the total aquatic product output (56.0321 million tons). At present, aquaculture has become a strong industry to improve the rural economic structure, solve farmers' employment and get rid of poverty. According to statistics, among the various production inputs of aquaculture, feed input cost is the largest. The survey shows that the fee...

Problems solved by technology

[0003] The purpose of the present invention is to provide a floating fish bait feeding device that prevents birds and water currents in order to solve the problem of feed waste caused by birds stealing feed and feed flowing out of cages with water flow in the current aquaculture process. The structure is simple, the operation is simple and easy, and the production cost is low. It can prevent the birds from stealing the feed and the feed flows out of the cage with the water flow, effectively solving the problem of feed waste.
