Large-scale large yellow croaker culturing device for high seas and deep seas

Abstract

The invention provides a large-scale large yellow croaker culturing device for high seas and deep seas, which comprises at least three buoys, wherein the buoys are connected with each other through purse nets so as to form a sealed culturing area, wherein the purse nets are formed by connecting net pieces in sequence; ropes are respectively arranged at the upper ends and the lower ends of the purse nets; floaters are arranged at the upper ends of the purse nets; net weights capable of enabling the lower ends of the purse nets to sink into sludge are arranged at the lower ends of the purse nets; the purse nets are expanded to form net walls, so that a bottomless culturing device is formed; sinking piles are arranged outside the purse nets at intervals; and the purse nets are connected and matched with the sinking piles through connecting ropes. The large-scale large yellow croaker culturing device has the advantages of strong wave resistance, large unit culturing area and convenience for placing and recycling; through the adoption of natural resources in the deep sea, artificially cultured large yellow croakers are acclimatized, so that meat qualities and mouth feels of the large yellow croakers are closer to those of wild large yellow croakers; therefore, the economic values of the artificial large yellow croakers are increased.

Description

technical field [0001] The invention relates to the technical field of aquaculture, in particular to a large yellow croaker breeding device, specifically, a large-scale large yellow croaker breeding device in deep waters of open seas. Background technique [0002] Large yellow croaker, belonging to the genus Scroakeridae and the genus Yellow croaker, commonly known as yellow croaker and yellow croaker, is a migratory fish in warm water clusters. It was once one of the four famous marine fishing targets in my country. For the "four big fish". With the overfishing in the early 1970s, the resources were severely damaged, and it has not been able to recover and cannot form a population. Wild large yellow croakers that can be caught today are very rare and expensive. Since the 1980s, people have continued to make up for the demand for large yellow croakers through artificial breeding. However, due to the limitation of the wind and wave resistance of the facilities, seawater cage...

Wild large yellow croakers that can be caught today are very rare and expensive

Since the 1980s, people have continued to make up for the demand for large yellow croakers through artificial breeding. However, due to the limitation of the wind and wave resistance of the facilities, seawater cage culture can only be carried out in shallow water areas in coastal harbors and the single cage area is small. , the water exchange is poor, and the breeding density is high, resulting in the color, strip shape, and taste of the cultivated yellow croaker being incomparable with the wild yellow croaker, so the value is not high

As for the "deep water cages" which have been widely introduced and used, although the supporting area of ​​individual cages has increased and the anti-wind and wave performance has been improved, the area of ​​individual cages is still limited and has not exceeded 1,000 square meters.

[0003] Existing publication number is that CN1393125 title is called " wind and wave deep water net cage " patent discloses a kind of buoyancy adjustable working platform, buoyancy ring and sinker anti wind and wave deep water net cage; Another publication number is that CN1568675 title is " can The patent of Submersible Deepwater Cage” discloses a submersible deepwater cage composed of cylindrical pipes, intermediate connectors, nets equipped with reinforcing ropes, vertically oriented counterweights, and intake and exhaust systems. The relative structure Complicated, difficult to operate and manage, high cost, difficult to popularize, ultimately unable to effectively achieve the goal of improving the quality of large yellow croakers
