Method and special device for enclosure culture of fishes

Abstract

The invention discloses a special device for enclosure culture of fishes. The special device comprises a cylindrical netting with the tail and the head connected, wherein an edge opening rope penetrates the upper edge opening of the netting; a traction rope is arranged on the outer side surface of the netting along the circumference and is connected with a ring-shaped floating body, so that the middle part of the netting can obtain traction buoyancy; and a sinker component is arranged at the lower edge opening of the netting in a penetrating manner, so that the lower edge opening of the netting can sink into sand and mud under the action of gravity. The invention provides the method and the special device for enclosure culture of fishes, which has the advantages of reasonable structure, convenience in construction, economy, high efficiency, stable volume of culture water body and small workload.

Description

technical field [0001] The invention relates to a method for cultivating aquatic products and its special cultivating equipment, in particular to a fish seine cultivating method and its special device. Background technique [0002] Ordinary net cage culture fish usually set multiple shallow net cages intermittently on floating rafts. Although the water resources are fully utilized, due to the small water body of the culture, in order to improve economic benefits, a higher density culture method is adopted, usually poses a risk of fish disease outbreaks. In order to prevent the above-mentioned risks, deep-water cage culture technology has been developed. Because it adopts large-scale net clothing, the utilization rate of water body is greatly improved, and the depth of culture water body is also increased a lot. However, it also has certain defects. For example, under the action of waves and currents, the netting will move with the current, and the actual aquaculture water b...

Problems solved by technology

Net pen culture has a long history in our country. It is usually the method and experience of intercepting a large water body (2-3 sides are banks) in lakes and rivers for fish farming. However, due to the small exchange of water bodies, it is also extensive and extensive. , lower yield and benefit

In addition, the layout of the fence adopts the construction form of bamboo poles inserted in a row and combined with ditching and burying the net, which consumes a lot of work.
