Description
Technical Field
The invention belongs to the field of fishery equipment manufacturing, relates to a deep water net cage for culturing reefs loving fishes in the deep and far seas, and particularly relates to a basalt fiber deep water net cage capable of shunting, lifting and internally arranging imitation reefs.
Background
The offshore cage aquaculture in China has a development history of more than twenty years, and deepwater cage aquaculture activities are developed in the east to the Dalian, the Qinhuang island, the tobacco station, the Qingdao, the south to the Zhuhai, the Zhanjiang, the North sea, the Hainan island and the south Shaji island. At present, main equipment for mariculture in China is a HDPE floating pipe wind wave resistant deepwater net cage or a large steel pipe truss liftable deepwater net cage, and the HDPE floating pipe net cage has the problems that the depth of a nylon or composite fiber net cover is 8-12 meters, the perimeter of the net cage is 30-80 meters, cultured fishes are easily injured when the net cage is just in a rolling region of sea waves in a typhoon period, and meanwhile, a large amount of crustacean marine organisms are attached to the net cover, the weight of the net cage is increased, holes are formed in the flexible net cover due to abrasion, and the cultured fishes die and escape. The large steel frame type net cage is difficult to fix, the net cage is difficult to abrade and tear at the net hanging points, the escape of the fish is caused, and meanwhile, the problems that the shellfish marine organisms are attached and difficult to clean are easy to occur to the metal truss and the net cage.
The existing deep water net cage can only culture floating seawater fishes such as large yellow croakers, golden pompanos and the like in upper water areas, but no net cage suitable for benthic reef loving fishes is available, and the benthic reef loving fishes are characterized in that a stone gap and a hole which can be attached to and attached to can hide the fishes are used for being accumulated in piles in gaps of seabed reefs with weak water flow or in water areas where island reefs can keep away from the water flow. The conventional deep water soft net is not suitable for reef-attaching fishes, due to the fact that the reef-attaching fishes inhabit at the bottom and gather in piles, the net cage swings up and down and left and right when stormy waves exist, the reef-attaching fishes are thrown out and turned over in piles, scraping injury is caused, fins on the back of the fish scrape and abrade net lines, holes are formed, the cultured fishes escape phenomenon is caused, and serious economic loss is caused.
Particularly, aiming at the special products of islands in south China sea, reefs-loving fishes, namely the groupers, the technology for cultivating the groupers in onshore industrial ponds in south China is mature, the cultivated groupers are produced by about 10 ten thousand tons every year in a cultivation scale and account for 80 percent of the market of the groupers in China, but the deep sea cage-cultivated groupers are not available. The main reasons are that grouper inhabits at the bottom and gathers in a pile, one side of the net cage is easy to be heavier, groupers roll in a pile after being affected by wind and waves, the groupers are easy to scratch and cause diseases and even death, the dorsal fins of the groupers easily abrade the existing flexible net cover, the groupers escape, and irrecoverable economic loss is caused.
Another reason that the existing deep water net cage is not suitable for culturing reef-loving fishes is that deep sea water space cannot be effectively utilized, the depth of the net cage is usually 8-12 meters, the reef-loving fishes are all accumulated at the bottom of the net after being full, the available water is very limited, the water with the depth of 15 meters below to 30 meters cannot be fully utilized, the culture density is low, the culture cost is high, the income is low, and the waste of the effective culture water is also caused. Therefore, no net cage suitable for deep and open sea culture suitable for reef-loving fish domestication and culture exists at present.
