Description

A kind of ecologic breeding mixing net cage
Technical field
The utility model relates to a kind of fish culture net cage, particularly a kind of ecologic breeding mixing net cage.
Background technology
In recent decades, the high speed development of mariculture industry brings very large negative effect to environment.Investigation is had to show, in the feed dropping into fish cultivating system, the fish food of nitrogen by not eating up of the phosphorus of about 85%, the carbon of 80%-88%, 52%-95%, excretion and the breathing of fish give environment, the organic or inorganic input of this fish meal, substantial impact is created on the organic matter in water and nutritive salt, may eutrophication be caused; The intensive cultivation of fish, shrimp, shellfish or other economic aquatic animals not only result in the ever-increasing nutrient concentration in coastal waters, result also in the change of dissolving inorganic nutrients structure and depositional environment, negatively may affect the biocoenosis in downstream in addition.
The formation of body eutrophication is mainly by the impact of the factors such as nutriment, dissolved oxygen, temperature, illumination, hydrodynamic force and bed mud.Wherein the increase of nutriment is basic reason; Dissolved oxygen, temperature and illumination can affect algal grown, cause the change of algal kind and quantity; When water body flow is slow, the diffusion of nutriment can be hindered, thus nutriment is accumulated, and also gives the hydraulics that those algae comparatively adapting to slow flow water bodies are suitable simultaneously; Dissolving, deposition dynamic equilibrium is there is in nutritive element between water body and basic sediment thereof, after exogenous nutrition thing enters water body, deposit in bed mud by physics, chemistry and biology effect, when water nutrition thing content drops to certain limit, nutrients in bed mud will be discharged in water body again, the eutrophication of aggravation water body.
In order to prevent and treat body eutrophication, the administering method used at present can be divided into physics, chemistry and biological method.Physical method refers to directly by dredging the method that the physical means such as desilting, the dirty reduction of discharging of joint is administered.These Measures compare are directly effective, but large-scale desilting dredging gigantic project, need substantial contribution, and the bed mud dug out and algae are difficult to safe disposal.Chemical method refers to comes organic matter in adsorption and sedimentation water and algae by adding chemical agent, or kills the method for algae.These methods need to add chemical agent in a large number, cost is larger, the chemical agent simultaneously added has toxicity or is difficult to decompose, destructible Marginal Sea Ecosystems long-term damage marine environment are when starting to use biological method, and people attempt utilizing the purifying water bodies such as microorganism, phytoplankton and Detritivorous fish.But utilize spatter property animal to carry out in the process of purification of water quality, animal itself also can carry out metabolism, produce metabolite, increase the weight of the load of ocean water body ecotope.Although phytoplankton can absorb a large amount of nutritive salt, phytoplankton population quantity is difficult to control, and is difficult to effectively be separated phytoplankton.
Compare with other clean biometric, tangleweed for the treatment of breeding wastewater and the maximum biology of marine ecology reparation, has a lot of distinctive advantage as present stage.The biofiltration research of G.caudata shows that tangleweed can reduce nutriment significantly, approximately can remove NH4 in 4 hours +59.5%, NO3 of-N -49.6% and the PO4 of-N 3-12.3% of-P.
Summary of the invention
The technical problems to be solved in the utility model is to provide a kind of ecologic breeding mixing net cage, this net cage can by shellfish, fish and algae mixed breed, both the growth of algae had been conducive to, marine environment can be improved by purifying water body again, the availability of bait can also be improved, improve the ability of resisting air quantity, reduce costs.
Object of the present invention realizes by following technical scheme:
A kind of ecologic breeding mixing net cage, is characterized in that: this mixing net cage is made up of shellfish culture net cage and fish culture net cage,

Described fish culture net cage is stainless steel cuboid framework, described fish culture net cage is fixed on the central authorities of shellfish culture net cage, the vertical and horizontal at four summits place of this fish culture net cage respectively stretch out two hawsers, and the other end of this hawser is fixed with two summits of the fish culture net cage of correspondence respectively;
The framework of the upper surface of described fish culture net cage is provided with the bait string bag, and this bait string bag extends internally; All be with interior purse seine in the surrounding of this cuboid framework, top and bottom, the aperture of this interior purse seine is 1.0-1.5cm, and in this fish culture net cage, cultivation has economic fish;
Top periphery between described fish culture net cage and shellfish culture net cage is planted on the net and is implanted with algae;
Described hawser is fixed with lifting rope or cage; Cultivate on this lifting rope or in cage and have Filter feeding bivalves; Shellfish can with the algae of the residual bait of fish, excreta and top for food, and algae can purify again the Water quality of surrounding, and the nutritive element in water can promote again the growth of algae.
Eight drift angle places of described shellfish culture net cage and four drift angle places of fish culture net cage are respectively provided with a spud pile, and this spud pile stands vertically in seabed.
Wherein, the length of side of described shellfish culture net cage is 18-20m, and the length of side of described fish culture net cage is 8-10m.The suitable size of two net cages, can resist the strike of stormy waves well, particularly in the summer that typhoon is prevailing, reduces economic loss.
Wherein, described Filter feeding bivalves is scallop, oyster or mussel; Described economic fish is Scioenops ocellatus, large yellow Crocker or little yellow croaker.
Wherein, the aperture of the described bait string bag is 1.0-1.5cm.Bait can be placed on toward in pocket, bait is slowly fallen by Action of Gravity Field, and fish can fully ingest, and improves bait utilization.
Described algae is laver, asparagus or Compositae weed.
Compared with prior art, the utility model has the advantages that:
1, described ecologic breeding mixing net cage achieves the ecologic breeding of shellfish, fish and algae, and shellfish can, with the algae of the residual bait of fish, excreta and top for food, prevent the high phosphorus nitrogen materials such as residual bait to cause the phenomenon of body eutrophication to occur; Algae can purify again the Water quality of surrounding, and the nutritive element in water can promote again the growth of algae.
2, the capacity of anti-storm of described ecologic breeding mixing net cage is strong, and can according to actual sea area situation, and the quantity of the whole net cage of flexible combination, shape and layout thereof, adaptability is stronger.
3, the setting of the described bait string bag, when feeding, bait is placed on the string bag, is slowly declined, improve bait utilization rate, reduce cost by Action of Gravity Field bait.
