Abstract

The invention discloses an offshore seining cultivation device. The device comprises a mooring system, a buffer system, a head rope, a seine and a bottom anchor, wherein the mooring system consists of a main rope, a main anchor and an auxiliary rope; the buffer system consists of middle floaters and sandbags; head rope floaters pass through the head rope; the seine is positioned below the head rope and is provided with a vertical manrope, a horizontal manrope and a ground rope; and the bottom anchor is connected with the horizontal manrope. The device is characterized by also comprising a tensioning rope tied to the joint of the main rope and the auxiliary rope, wherein the other end of the tensioning rope is tied to the seine; the sandbags are tied to the tensioning rope; and a circle of waist floaters is arranged on the seine below the tie point of the tensioning rope and the seine. An anti-escape net is fixed on the inner side face of the seine between the horizontal manrope and the ground rope, and extends out of the seine, and the bottom of the anti-escape net is provided with an anti-escape ground rope. The device has the advantages of simple structure, convenient operation, effective prevention of the stack and wear of seines and the escape of the cultivation products, suitability for the seining cultivation in various offshore areas, and significant meaning and effect on the cultivation of various economic aquatic products.

Description

technical field

[0001] The invention relates to an aquaculture device, in particular to a purse seine culture device suitable for offshore. Background technique

[0002] Seine aquaculture is to cultivate economic aquatic products in a certain area surrounded by meshes in fresh water and sea waters. It is an ecological breeding method that combines artificial and natural bait and is closer to the natural environment. It has the characteristics of wide breeding area, low investment, quick effect and no need for oxygenation.

[0003] At present, the purse seine culture device mainly consists of several vertical poles and aprons and sandbags (sinks) etc., and the vertical poles play a supporting role, the garments are bound on the vertical poles, and the bottom is fixed on the bottom of the water with sandbags (sinks). This farming device is mainly suitable for areas such as lakes or tidal flats with small wind waves and tidal ranges, while the marine environment (wind waves an...
