Technical field
The invention belongs to aquacultures and marine resources development field, and in particular to one kind fishes cultivation for huge net cage
The device of fish is used to support seawater fish cage culture and expands to far-reaching sea.
Background technique
With the fast development of China's mariculture industry, the extensive sea-farming in coastal waters brings industry conflict, ecology danger
A series of problems, such as evil, pest and disease risk, quality safety.Therefore, mariculture industry is expanded from coastal waters to offshore and far-reaching sea
Inexorable trend as China's sea-farming industry development.
As cage culture offshore is more and more remoter, the depth of water and sea situation rank are also increasing, and the net cage volume of cultivation is also got over
Come greatly, therefore cultured fishes capture technique has become problem concerned by people.At present people pass through frequently with cage-farming
Fishing technology include cast net fishing, purse seine fishing in net cage, etting pull-up caught etc., the advantages of these fishing styles is letter
Easily, the disadvantage is that needing more manpower.Force ship heavy industry is that the semi-submersible type steel frame construction net cage that Norway builds has used machinery in the recent period
It drives, the method for mechanical lifting；The full submersible net cage of " dark blue No. 1 " in China then uses buoyancy tank halieutics.This latter two net cage
Halieutics it is excessively complicated.And it also needs to start entire fishing system for fishing part fish, the cultivation to fishing is not planned
Fish have certain injury.All it is badly in need of a kind of easy mechanization batch fish-catching apparatus both at home and abroad at present.
