Abstract
The utility model relates to a pyramid-shaped oyster reef suitable for growth of oysters. The pyramid-shaped oyster reef suitable for growth of oysters comprises a reef body. The reef body is an equilateral triangle body composed of six edges. The six edges are composed of six columnar net bags. The six columnar net bags are bundled at the ends of adjacent net bags in the included angle of 60 degrees to form the hollow pyramid-shaped reef body. The pyramid-shaped oyster reef suitable for growth of oysters is suitable for coastal shores with the high sediment deposition speed and the pyramid-shaped oyster reef suitable for growth of oysters is arranged. The reef body has the good stable feature, the pyramid-shaped oyster reef suitable for growth of oysters also can serve as the inhabiting place for aquatic organisms and the favorable conditions are provided for oyster fixation and maintenance of biodiversity of an oyster reef ecological system.
Description
Technical field
The utility model belongs to oyster ecosystem prosthetic device field, particularly relates to a kind of pyramid oyster bioherm that improves marine ecology physicochemical environment and be beneficial to oyster growth, breeding.
Background technology
Oyster bioherm is the reefs being formed by a large amount of oyster aggregation growths; the oyster bioherm ecosystem of its formation has important ecological functions and value, at water body purification, perch habitat formation, bio-diversity conservation, Coupling Ecosystem energy flow, stablize coastline and substrate and promote the aspects such as Cycle of nutrients all to have a very important role.Due to the aggravation of the engineering construction activities such as reclaiming fields from the sea of exhaustive exploitation to wild oyster resource of the mankind in recent years, strand bank, cause wild oyster quantity sharply to decline, environmental pollution, the aggravation of Sediment Siltation speed are even withered away the acceleration atrophy of oyster bioherm habitat.As the overfishing of U.S. Chesapeake gulf oyster resource and the heavy damage in habitat, cause this river mouth, ground Eutrophic Extent aggravation, fishery production decline and aquatic ecosystem degeneration etc.Therefore, the maintenance to the oyster bioherm ecosystem and reparation seem particularly necessary.
Both at home and abroad the achievement in research of oyster bioherm maintenance is shown at present, the effective way of oyster bioherm maintenance is artificial oyster propagation and makes reef.Because oyster belongs to marine benthos, the most times in its history of life are all bonded to hardground, therefore for oyster provides growth and breeding to oyster of suitable adhesive substrate and the maintenance of oyster bioherm, play crucial effect.
Summary of the invention
Technical problem to be solved in the utility model is to provide a kind of pyramid oyster bioherm that is applicable to oyster growth, suitable to the larger strand bank of sedimentation speed, setting is applicable to the pyramid oyster bioherm of oyster growth, reefs has good firm characteristic, the place that can also perch as aquatile, for set, the maintenance of oyster bioherm ecosystem bio-diversity of oyster provide advantage.
The utility model solves the technical scheme that its technical problem adopts: a kind of pyramid oyster bioherm that is applicable to oyster growth is provided, comprise reefs, described reefs is the positive triangle body being comprised of six ribs, article six, rib is comprised of 6 column mesh bags, described 6 column mesh bags are respectively bound in the end of adjacent mesh bag with 60 degree angles, form a hollow pyramid reefs.
Described mesh bag is cylindrical, by etting, works out.
Discarded shell is housed in described mesh bag.
Described mesh bag diameter 28-320m, length is 90-110cm.
Described etting is formed by the braiding of polyethylene nettle, and mesh is 1-2.5cm.
Beneficial effect
The utlity model has following advantage and good effect:
(1) rough surface of reefs increases the probability that adheres to of the oyster young.
(2) reefs is pyramid, can farthest bring into play the stability of triangular structure.
(3) reefs main body forms by discarding shell, twice laid, and reduce reefs construction cost.
(4) reefs four sides only simultaneously contacts with sediment, and its excess-three face is all exposed in seawater, extends reefs and buries the sunken time in seabed, increases the service life of reefs.
(5) reefs is hollow-core construction, and reefs itself is except being applicable to oyster set, still has a fish gathering effect of artificial fish shelter, for the aquatile in the oyster bioherm ecosystem provides to perch, protects place.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Embodiment
Below in conjunction with specific embodiment, further set forth the utility model.Should be understood that these embodiment are only not used in restriction scope of the present utility model for the utility model is described.In addition should be understood that those skilled in the art can make various changes or modifications the utility model after having read the content of the utility model instruction, these equivalent form of values fall within the application's appended claims limited range equally.
As shown in Figure 1, a kind of pyramid oyster bioherm that is applicable to oyster growth, comprise reefs, described reefs is the positive triangle body being comprised of six ribs, article six, rib is comprised of 6 column mesh bags 1, described 6 column mesh bags 1 are respectively bound in the end of adjacent mesh bag 1 with 60 degree angles, form a hollow pyramid reefs.
Described mesh bag 1 is cylindrical, by etting 2, works out.
Discarded shell 3 is housed in described mesh bag 1.
Described mesh bag 1 diameter 28-320m, length is 90-110cm.
Described etting 2 is formed by the braiding of polyethylene nettle, and mesh is 1-2.5cm.
A pyramid oyster bioherm that is applicable to oyster growth, is applicable to render to the strand bank that sedimentation speed is larger, for set, the maintenance of oyster bioherm ecosystem bio-diversity of oyster provide advantage.Oyster bioherm is respectively tied up and is formed hollow Pyramid reefs with 60 ° of angles by 6 cylindrical mesh bags 1 of filling shell, and mesh bag is formed by 2 braidings of polyethylene etting, the discarded shells 3 such as interior filling oyster shell, and reefs has good firm characteristic, rough surface.Oyster bioherm is except being applicable to oyster set, still has a fish gathering effect of artificial fish shelter, for the aquatile in the oyster bioherm ecosystem provides to perch, protects place.Oyster bioherm all can be placed at silt substrate and petrofacies substrate, has applicability more widely.
