Abstract
The utility model provides an oyster reef with sediment accumulation resistance, and relates to a device for restoring an oyster ecological system. According to the technical scheme, cylindrical mesh bags and waste seashells are adopted. The oyster reef is characterized in that the waste seashells are filled into the cylindrical mesh bags, rough cylindrical surfaces are formed on the surfaces of the cylindrical mesh bags, the six cylindrical mesh bags filled with the waste seashells are connected into a hollow triangular-pyramid-shaped reef body, wherein the included angle between every two adjacent cylindrical mesh bags is 60 degrees, and the ends of the cylindrical mesh bags are bundled up. The oyster reef is suitable for being placed in coasts with the high sediment accumulation speed and provides advantages for fixation of oysters and maintenance of biodiversity of an oyster reef ecological system.
Description
Technical field
The utility model relates to the device that a seed oyster ecosystem is repaired.
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 mankind to engineering construction activities such as reclaiming fields from the sea of the exhaustive exploitation of wild oyster resource, strand bank in recent years, 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.Therefore, the maintenance of the oyster bioherm ecosystem and reparation are seemed to 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 suitable adhesive substrate, the maintenance of the growth and breeding of oyster and oyster bioherm are played to crucial effect.
Summary of the invention
The purpose of this utility model is to provide a kind of oyster bioherm of anti-Sediment Siltation.
The technical solution of the utility model adopts cylindrical mesh bag and discarded shell, it is characterized in that the discarded shell of filling in cylindrical mesh bag, on cylindrical mesh bag surface, form the coarse face of cylinder, by the cylindrical mesh bag of 6 discarded shells of filling each with 60 ° of angles and tie up in end and connect into a hollow Rhizoma Sparganii taper reefs.
The beneficial effects of the utility model are: the rough surface of reefs increases the probability that adheres to of the oyster young; Reefs is Rhizoma Sparganii taper, can farthest bring into play the stability of triangular structure; Reefs main body forms by discarding shell, twice laid, and reduce reefs construction cost; Reefs four sides only one side 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; 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
Embodiment 1: as shown in Figure 1, the discarded shell 3 of filling in cylindrical mesh bag 1, on cylindrical mesh bag surface, form the coarse face of cylinder, by the cylindrical mesh bag of 6 discarded shells of filling each with 60 ° of angles and tie up in end and connect into a hollow Rhizoma Sparganii taper reefs; Discarded shell 3 is the body of the large-scale shellfishes such as discarded oyster, mussel.
Embodiment 2: according to the frame mode of embodiment 1, and the most handy diameter 30cm of cylindrical mesh bag 1, length is 100cm, the mesh of polyethylene netting twine 2 braidings is the cylindrical mesh bag of 2cm.
Claims (2)
1. the oyster bioherm of an anti-Sediment Siltation, adopt cylindrical mesh bag and discarded shell, it is characterized in that the discarded shell of filling in cylindrical mesh bag, on cylindrical mesh bag surface, form the coarse face of cylinder, by the cylindrical mesh bag of 6 discarded shells of filling each with 60 ° of angles and tie up in end and connect into a hollow Rhizoma Sparganii taper reefs.
2. the oyster bioherm of a kind of anti-Sediment Siltation according to claim 1, is characterized in that: described cylindrical mesh bag diameter 30cm, and length is 100cm, etting mesh is 2cm.
