Description
Technical field
The utility model relates to bay, coastal opening marine site fishery cultivating technology, is specifically related to a kind ofly improve coastal closing and the device of efficiency of feed utilization in bay, semiclosed marine site cage culture bait throwing in process.
Background technology
Marine fishes provide a large amount of high-quality proteins to people, and China has wide coastline, and seawater fishery industry is in China's fast development, and cultivation abundant species, enormous amount, typical fish are as Cymbaria dahurica, little chrysanthemum, basket fish etc.The features such as marine fishes have high protein, delicious meat, and mouthfeel is good, nutritive value is high liking deeply by consumers in general.Therefore world many countries is all greatly developing sea fishery.
But, due to the ecologic structure of aquaculture self and the defect of breeding way, make major part cultivation there is a lot of environmental problem.In aquaculture process, bait refuse exists with the solubilised state of organic or inorganic thing and particulate form, and its total amount applicable biological analysis and chemical analysis are estimated.With expansion and plant's prolongation service time of cultivation scale, add N and P content in water body, change the vertical distribution of chemokines in water body, accelerate the eutrophication of aquaculture sea area; Facilitate fouling organism growth, the nutritive salt load in waters and the living load of breeding facility are increased all to some extent; Have stimulated phytoplankton breeding, even produce wawter bloom; In culture zone, bacterium increases, dissolved oxygen concentration reduction etc.The organic loading that residual bait, fish excrement etc. produce is the immediate cause causing above-mentioned change, and they make the Flux of cultivation water body suspended particle significantly increase, and accumulate in seabed, change former bottom environment, and restriction carrying capacity, causes plant aging.Fish can not ingest and assimilate whole bait, and residual bait and fish excrement accumulate in bottom culture zone, become the main source of substrate pollution.
In existing cage culture process, the Sinl'Perca chuatsT of employing is comparatively traditional, and namely directly bait throwing in is in net cage, and bait of not ingesting floats loose everywhere, works the mischief to net cage and surrounding S & W body environment.Controlling the organic quantity of substrate is the fundamental starting point reducing cage culture environmental pollution and repair bottom environment.Therefore, how improving bait utilization, is one of direct way reducing cage culture district particle load.
The fishery cultivating in current coastal opening marine site adopts shallow sea cage culture mostly, fish culture net cage utilizes that foam is cursory, plank or floating bamboo across the sea floating, net cage is by anchoring due under water, and most several net cage connects together.Bait mostly swam in sea before not eaten up, bait throwing in adopts directly toward dispenser in net cage, this Sinl'Perca chuatsT is easy to the waste causing feed, a large amount of residual baits wafts to outside by wide-aperture net cage under the effect of wave, cause waste, increase aquaculture cost, and the bait being floated to outside can pollute the marine environment of aquaculture sea area.
Summary of the invention
The utility model technical issues that need to address are: existing fish culture net cage is when bait throwing in, be easy to the waste causing feed, a large amount of residual baits wafts to outside by wide-aperture net cage under the effect of wave, cause waste, increase aquaculture cost, and the bait being floated to outside can pollute the marine environment of aquaculture sea area.
The utility model takes following technical scheme:
Improve a device for bait utilization in fishery cultivating process, comprise net cage 1, anchor, foam plastic float 5, central lace curtaining 2, main rope 6, sinker 3, plank 8; Described net cage floats on the water surface under the effect of foam plastic float 5 and plank 8, fixed by anchoring; Two main ropes 6 connect the lower edges of central lace curtaining 2; The corner of lace curtaining water surface part pulls to net cage corner with four main ropes 6 respectively and is fixed; The below of central authorities' lace curtaining 2 is fixed every segment distance sinker 3 hanging; The part of central authorities' lace curtaining 2 is submerged under water, and part is suspended from the water surface, and the region of central lace curtaining 2 is feedstuff feeding region.
Further, lace curtaining aperture is 2mm, high 0.8m, and wherein 0.4m is positioned on the water surface, and 0.4m is positioned under the water surface.
Further, central lace curtaining 2 four back gauge net cage 1 vertical range is not less than 0.5m.
Further, for preventing lace curtaining floating, fix with sinker every 0.5 meter in the below of lace curtaining.
Further, described central lace curtaining 2, by the main rope 6 of four diagonals, pulls to the corner of net cage respectively, and the corner of net cage is fixed in artificial knotting.
The beneficial effects of the utility model are:
1) bait of net cage of can making to throw something and feed swam among lace curtaining before not ingested, and was unlikely to be blown out net cage by wave, caused waste.
2) substantially increase the availability of feed in steck breeding process, save aquaculture cost.
3) decrease remaining feed that cultured fishes do not utilize to the pollution of marine environment, improve the transparency of breeding environment in steck.
4) under the effect of diagonal pulling, the intensity of net cage increases greatly simultaneously, and capacity of anti-storm and service life significantly strengthen.
5) the suitableeest daily ration, feeding quantity of net cage can also be estimated by the amount of bait residual in lace curtaining after each bait throwing in.
6) the lace curtaining cost for tackling residual bait is lower, can large-scale popularization use.
