Big fixed net cage for cultivating seawater fishes and using method thereof

Abstract

The invention belongs to the field of seawater cultivation engineering and particularly discloses a big fixed net cage for cultivating seawater fishes and a using method thereof. The big fixed net cage for cultivating the seawater fishes and the using method thereof solve the problems of poor anti-typhoon capability, more diseases, high making cost and the like of the current net cages. Piles of the net cage are distributed along the periphery; a net encloses the piles to form a cage structure; the upside and the lower side of the net are coiled by an upper net cable and a lower net cable; the tops of the piles are connected with diagonal tension cables II; the upper parts of the piles are connected with diagonal tension cables I; and the tops of the corresponding piles are connected by transverse cables. By piling piles under the sea and providing the transverse cables, the diagonal tension cables, the upper and lower cables of the nets to fix the big nets, the cultivating capacity of the net cage is improved, the cultivating cost is reduced, the quality of the cultivated fishes is improved and the cultivating environment is protected. The big fixed net cage for cultivating the seawater fishes and the using method thereof make a full use of and maintain a good ecological environment for cultivation, produce the highly qualified seawater fishes, prevent the cultivating area from being polluted and prevent the occurrence of diseases in the aquaculture, improve the living environment for the cultivated fishes and reduce losses due to natural disasters.

Description

technical field [0001] The invention belongs to the field of marine aquaculture engineering, and specifically relates to a fixed large net cage for cultivating seawater fish and its use method. It is a large net cage design method for increasing the water body of fish culture by driving piles on the seabed to fix the net clothing . Background technique [0002] Cage fish farming is an intensive farming method in large waters. It forms an ecological environment suitable for fish growth in the cage through the free exchange of water inside and outside the cage, and a method of high-density farming. It has the advantages of making full use of natural sea areas and harbor waters, not occupying land cultivated land, high output per unit area, short breeding cycle, high feed conversion, wide range of breeding objects, convenient operation and management, high labor efficiency, high degree of intensification and significant economic benefits, etc. features. The aquaculture cages ...
