Abstract
The utility model discloses an ecological type fish shell polyculture net cage comprising a gravity type net cage, wherein a demersal shellfish culture device is arranged at the bottom of the gravity type net cage and provided with a rectangular main body plate; culturing holes are uniformly distributed in the main body plate, and an archy adhering groove is manufactured in each culturing hole; and positioning holes are formed in side walls of the adhering grooves, and aeration pipes are arranged in the positioning holes in a penetrating mode. The demersal shellfish culture device is arranged at the bottom of the gravity type net cage for culturing shellfish, and residual baits and excrement of cultured fishes on the upper layer can be effectively adsorbed. Through adsorption of algae and the shellfish on the bottom layer, discharging of organics can be greatly reduced, and environment stress is reduced. The ecological type fish shell polyculture net cage has the advantages of being convenient to manage, low in cost, convenient to manufacture, high in culturing density, good in culturing weight increment effect, and eco-friendly.
Description
Technical field
The utility model relates to a kind of offshore type high-density aquiculture facility, relates in particular to environmental fish shellfish and raises together with net cage.
Background technology
In the ocean, the shallow sea fishery resources be now with main, the most direct resource that future, the mankind relied on, it provides most of protein requirement of the mankind.But the shallow sea About The Ecosystem of Fishery is owing to being subjected to the effect of human activity, and ecotope is increasingly serious, and the normal activity of fishery resources has been upset in these activities of the mankind, and the About The Ecosystem of Fishery function is damaged, and the shallow sea About The Ecosystem of Fishery has faced serious crisis.For the globality of keeping the shallow sea About The Ecosystem of Fishery with and continuous production and normal function, the About The Ecosystem of Fishery that not only needs protection be the more important thing is the mechanism of its functional deterioration of research and recovery and the reconstruction of function.Shellfish is generally phytophagy, mainly ingest algae and organic debris etc., and feed foundation is abundant.Inner bay one band nutrient concentrations in river mouth is high, a large amount of phytoplanktons that can grow, and the urban sewage of rivers runoff and injection becomes the abundant food source of shellfish often with a large amount of organic matters, is the ideal place of shellfish culture.The fish-farming in shallow marine water shellfish does not need bait throwing in, can support the sea vast; Mudflat aquaculture does not generally need cost to set up cultivation ground yet, puts in a suitable place to breed after seed and can gather in general 1～2 year, and cost is low and earn a large income, and therefore, shellfish culture has become the important component part of aquatic products industry.Carry out fish-Bei-ecological compound utilization and ecosystem function recovering technology such as algae; technology, ecological engineering designing technique, the ecosystem that degeneration was controlled and slowed down in research build integrated technology; progressively implement scientific management and the reparation of living marine resources; to promoting protection and the sustainable development of the coastal ocean ecosystem, promote recovery and the development of fecundity of the sea to be significant.
Summary of the invention
The purpose of this utility model be for prior art a kind of convenient management is provided, with low cost, easy to make, cultivation density is high, cultivation gaining effect good, eco-friendly environmental fish shellfish is raised together with net cage.
The utility model solves the problems of the technologies described above the technical scheme that adopts: environmental fish shellfish is raised together with net cage, comprises gravity type net box, wherein: be provided with the benthic mollusca cultivator bottom gravity type net box; The benthic mollusca cultivator has the main board of rectangle; The main board gap is evenly equipped with and cultivates the hole, and each cultivates the groove that adheres to that is shaped with arch on the hole; The sidewall that adheres to groove is shaped with to run through in locating hole and this locating hole and is provided with gas tube.The gravity type net box bottom is provided with the benthic mollusca cultivator and is used for cultivated shellfish, can effectively adsorb residual bait and the excreta of upper strata cultured fishes.By bottom algae and shellfish absorption, can greatly reduce organic discharging, reduce environmental pressure.Adhering to groove and can adhere to shellfish on main board, and because its surface area is large, open ended biomass is also relatively high.Run through being provided with gas tube and being positioned at the part of adhering to the groove inboard and having micropore in locating hole, be used for carrying out artificial oxygenation to adhering to groove.
For optimizing technique scheme, Adopts measure also comprises: the main board downside is shaped with paired clip bar, and the spacing of clip bar can coordinate clip to adhere to the groove head portion just.The clip bar can make a plurality of the utility model devices be stacked into cubic, thereby increases carrying capacity.At this moment, only need to inflate the gas tube that is positioned at bottommost, cultivate along with bubble successively passes the inflation that the trough inner water body can be realized all are adhered in the hole, namely saving the energy increases again carrying capacity.
Spacing between the cultivation hole is more than or equal to the width that adheres to groove.The advantage of this design is to prevent that the groove that adheres to of lower floor from penetrating in cultivation hole, upper strata and be expressed to aquaculture organism.
Benthic mollusca cultivator formula is: contain by weight percentage
350～800 order cast iron powders 25～30%;
Curing aluminium dry powder doses 1～3%;
Super high molecular weight low-pressure polyethylene surplus.
The molecular weight of super high molecular weight low-pressure polyethylene masterbatch is in 2,500,000 ten thousand units of unit to 400.
Also contain in formula: graphite powder 3～5% or calcium stearate 3～5% or spherical silicon-base oxide nano powder 0.1～0.2% or its combination.
Because the environmental fish shellfish of the utility model is raised together with net cage, adopted the main board gap to be evenly equipped with the cultivation hole, and be shaped with the groove that adheres to of arch on each cultivation hole; The sidewall that adheres to groove is shaped with to run through in locating hole and this locating hole and is provided with gas tube.Adhering to groove and can adhere to shellfish on main board, and because its surface area is large, open ended biomass is also relatively high.Run through being provided with gas tube and being positioned at the part of adhering to the groove inboard and having micropore in locating hole, be used for carrying out artificial oxygenation to adhering to groove.Thereby, the utlity model has convenient management, with low cost, easy to make, cultivation density is high, good, the eco-friendly advantage of cultivation gaining effect.
