Large-scale ecological purse seine breeding device in shallow sea

Abstract

The invention discloses a large-scale ecological purse seine breeding device in shallow sea. The large-scale ecological purse seine breeding device in the shallow sea comprises a buoyancy system, a netting system, a dragon-shaped sandbag and an anchoring system, wherein the buoyancy system comprises double-row main floating pipes which are arranged in a parallel mode at intervals and a shore connecting structure which is fixedly arranged on the shore; two ends of the main floating pipes are respectively connected to the shore connecting structure and can longitudinally move up and down relative to the shore connecting structure; the netting system comprises a purse seine and the upper end of the purse seine is fixedly connected with the main floating pipes; the dragon-shaped sandbag is arranged at the bottom of the netting system; the anchoring system comprises a main anchor rope, the upper end of the main anchor rope is connected to the main floating pipes, and the lower end of the main anchor rope is fixedly arranged at the bottom of the sea through a piled anchor or an anchor block. The large-scale ecological purse seine breeding device in the shallow sea has the advantages of meeting the strength requirement of the buoyancy system of the purse seine by utilizing a mode of fixing the purse seine under the HDPE (high-density polyethylene) main floating pipes; ensuring a purse seine system to be always connected closely with a coastal connecting section and avoiding escape of the fish due to the fact that a buoy which is arranged in the shore connecting structure changes along with water levels; and being capable of avoiding the purse seine winding under different tide levels by arranging a chain and a floating ball string in the purse seine.

Description

technical field [0001] The invention relates to a shallow sea culture device, in particular to a shallow sea large-scale ecological seine culture device. Background technique [0002] Aquaculture in marine facilities has made an important contribution to the economic development of marine fishery in my country. At present, seine culture, raft culture and cage culture are the most important methods for the development of marine aquaculture. Among them, large-scale seine culture in shallow seas is the expansion of traditional inshore tidal seine culture to deep waters in the open sea, but structurally It is significantly different from the traditional coastal tidal flat seine project. Generally, it can be fenced on one or more sides by relying on the outer islands. It will be one of the important forms of marine facility breeding in the future. [0003] Compared with other farming models such as deep-water cage culture, large-scale seine aquaculture in shallow seas has signif...

AI Technical Summary

Problems solved by technology

During the breeding process, many hard-shelled marine organisms will be attached to the poles. When there are wind waves and tidal ranges, the seine will rub against the hard-shelled marine organisms on the poles with the ups and downs of the sea water, and the seine will Considering the tidal range, the depth is designed based on the high tide level, and there will be slack at low tide levels, which will cause damage to the seine net and cause the breeding objects to escape from the seine net

And most of the damaged parts of the seine are concentrated in the water and are difficult to detect, so that the application of the above-mentioned aquaculture device is greatly restricted
