Description
Technical field
The utility model relates to a kind of net cage aquaculture device for feeding fish bait, belongs to aquaculture device technical field.
Background technology
The decline of China coastal seas wild fishery resources is serious, and day among adding, the coming into force of Sino-Korean fisheries agreement, seawater fish cage culture becomes the Preferential Developmental Industry of fishing for transferring fishermen's job, fisheries structural adjustment.Cage culture has intensive, the feature such as high density, high benefit, is the main force of China's fishery new industry.According to incompletely statistics, national marine fish culture net cage about has more than 70 ten thousand, and the cultured fishes forming scale also have kind more than 30.China's Net Cage Culture of Marine Fishes bait is mainly based on chilled trash fish, and within 2006, national marine fish culture output is 770,000 t, has the cultured output of more than 80% to be that iced trash fish shrimp by throwing something and feeding freezing obtains.These easily cause following problem based on the bait of chilled trash fish shrimp: one is the destruction of aggravating further coastal water fishery resource; Two is pollute marine environment and water quality; Three is due to changes such as weather, season, sea situations, cannot ensure there are enough feed fish supplies every day, affect breeding production; Four is because water quality, substrate pollution and feed fish cannot be guaranteed supply, and can bring out the generation of disease; Five is nutritional imbalances, causes that cost is high, of poor quality, benefit is low.For addressing these problems, have developed efficient, the low stain artifical compound feed for seawater fingerling palatability and nutrition-allocated proportion in recent years, this kind of feed is mostly graininess.At present, Ningbo City, Zhejiang Province has started to advance at administrative Area of The East China Sea forbids adopting chilled fish to carry out the cultivation of the fingerlings such as yellow croaker, progressively adopts artifical compound feed to substitute.
Used in mariculture granular bait for fish is a dead lift and throwing something and feeding at present substantially in the mode of throwing something and feeding, and labour intensity is large, inefficiency, especially needs in the fry cultivation stage that trace is multiple batches of throws something and feeds, and is washed away by ocean current to prevent bait.
In addition, research shows at feed coefficient, slow heavy property bait suppose that mask has significant advantage compared with buoyancy bait, but existing net cage feeder is when throwing is raised, and bait usually has little time to be sunk to seabed by eating up, and both polluted seawaters, also result in waste.
Bait throwing machine for fish pond is directly applied to net cage cannot address this problem, main cause has cage size little, and the bait face of shedding can not be too large; Further, device for feeding fish bait is directly fixed on net cage lattice, can only directed bait throwing in, and bait is thrown in uneven, and cause cultured fishes nutritional imbalance, body size differs.Especially the fingerling such as large yellow Crocker, when feeding certain specification, can form the high density shoal of fish, if bait throwing in inequality will cause the shoal of fish and rob food, causing the phenomenon of shoal of fish hypoxia death in net cage.
