Description

Coral nursery frame for preventing fishing net

Technical Field

The utility model relates to a coral nursery frame of anti-fishing net.

Background

The coral reef distributed in tropical low-latitude oceans is an important marine ecosystem which integrates ecological resources, environmental regulation, leisure and entertainment, coastal protection, homeland safety, mineral oil and gas and scientific culture, is one of ecosystems with global biodiversity and most abundant resources, is known as 'tropical rainforest' in oceans and plays a vital role in the health and sustainable development of human society and marine ecological environment. However, in recent years, highly disturbed human activities cause extremely serious environmental pollution, ecological damage and the like to the ocean, resulting in serious damage to the coral reef ecosystem, even difficult recovery.

For healthy slightly damaged coral reefs, the natural recovery can be realized within a certain time; for some more seriously damaged coral reef ecosystems, natural recovery may take hundreds of years, and human intervention is usually required to rebuild the ecosystem. The artificial reef foundation and the nursery frame are built and put into the damaged coral reef area or the existing coral reef is repaired manually, so that the coral reef habitat is reconstructed. The artificial reef base and the coral nursery frame are beneficial to improving the complexity of the three-dimensional structure of the coral reef, provide good and stable inhabitation and breeding places for marine organisms, and can ensure that the coral attached or transplanted to the artificial reef base can have a solid base to avoid the influence of loose base, reduce the predation of enemy organisms, improve the survival rate and accelerate the repair process of the coral reef ecosystem.

Most of nursery racks put in at present can promote the broken branches of transplanted corals to grow to a certain extent due to different designs and shapes, but are almost easily interfered and damaged by artificial fishing nets, so that the coral seedlings growing immediately are damaged, the growth rate of corals is low, and the coral reef ecological restoration effect is limited.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to overcome prior art's not enough, provide an artifical coral nursery frame, this nursery base not only can avoid the fishing net influence, and simple manufacture, put in convenience, sound construction, do benefit to the coral lopping growth and development of transplantation, also can promote other marine organisms to perch simultaneously and multiply for the coral reef ecosystem restores the process.

In order to realize the purpose, the utility model discloses a technical scheme as follows:

a coral nursery frame with a fishing net prevention function comprises a seedbed and supporting columns, wherein the four corners of the seedbed are respectively connected with the supporting columns which are vertically arranged; the seedbed is covered with a knotless net;

a blocking net frame is arranged above the seedbed, the blocking net frame and the seedbed are the same in size, and four corners of the blocking net frame are respectively connected with the support columns; and reinforcing ribs are arranged between the support columns and the edges of the seedbed.

Preferably, each pillar is provided with two reinforcing ribs, and the other ends of the two reinforcing ribs on any pillar are connected with two adjacent sides of the seedbed respectively.

Preferably, two mutually perpendicular reinforcing steel bars are further arranged on the seedbed.

Preferably, the seedbed is square and has a side length of 100-200 cm.

Preferably, the vertical distance between the seedbed and the bottom of the support is 80-110 cm.

Preferably, the vertical distance between the seedbed and the screen blocking frame is 30-40 cm.

The utility model discloses owing to adopted above-mentioned technical scheme, following beneficial effect has:

1. can prevent the damage of the fishing net and promote the growth of coral branches. The utility model discloses a have the block frame that encircles the round on the coral nursery frame, can greatly prevent the trawl, the fishing net interference destruction of fishery activity to the coral broken branch of protection nursery bed is avoided the fishing net and is influenced, greatly improves the coral seedling survival rate of transplanting, growth rate.

2. Has good stability and circulation. The artificial nursery frame is integrally in a cuboid framework and hollow in the body, and the support columns are driven into the seabed through the underwater electric drill and the fixing tool, so that the artificial nursery frame is solid and firm and is not easy to be washed down and displaced by seawater; the support column and the seedbed are also connected through reinforcing ribs to form a stable triangular structure, so that the nursery frame is more stable. The seedbed is provided with a plurality of orifices without a net, so that a plurality of holes and cracks in the coral reef structure can be simulated really, and the smooth flow of natural ocean currents is promoted.

3. Provides habitat for various coral reef organisms and promotes the growth and development of the transplanted coral branches. The artificial nursery frame is in a hollow frame type structure in the body, and a seedbed formed without a net is provided with a plurality of orifices, so that various coral reef organisms can freely enter and exit, foraging is carried out, and natural enemies can escape; the organic matter and a large amount of phytoplankton on the bottom layer can be carried to the top by ocean currents, so that the coral and other organisms are provided with richer food sources and nutrients, and the growth and breeding of the corals and the organisms are promoted. Meanwhile, the surface of the coral filter stick is beneficial to the attachment and growth of coral in sexual propagation and is convenient for the inhabitation of other microorganisms. These all contribute to the survival and development of coral broken branches, and further promote the ecological reconstruction of coral reefs.

4. Greatly improves the biodiversity and ocean primary productivity and promotes the restoration of the coral reef ecosystem. The utility model discloses not only resisted the destruction of fishing net, promoted the growth and development of coral disconnected branch and the adhesion of coral, realized the gathering of a large amount of corals, still provided the place of perching, foraging, breeding for marine organisms such as fish, shellfish, tentatively rebuild coral reef ecosystem, improved the biodiversity and the primary productivity of restoreing the sea area.

Therefore, the utility model has the characteristics of the design, both reduced the three-dimensional structure in coral reef district, also increased the circulation of sea water, provide more suitable growing environment for coral disconnected branch, promote the formation and the recovery of coral reef crowd. The utility model discloses a prevent the manufacturing in the artificial coral nursery of fishing net with better design theory, greatly promote the growth and development of coral seedling, the coral reef that development was restoreed can play the effect that the breakwater was protected to the breakwater, was protected the coastline. This artificial coral nursery can satisfy biological growth's key demand, has especially built the growing environment who does benefit to the coral seedling, promotes the calcified deposit of coral, and then has accelerated the ecological remediation process of coral reef, has very big ecological value.

Moreover, the utility model can bring great economic and social benefits, and the artificial coral nursery can promote the coral reef organisms to inhabit and breed, thereby bringing a great amount of fishery resources to nearby sea areas; meanwhile, the method can also be used for carrying out marine ecological restoration and protection demonstration, providing scientific investigation data, promoting science popularization education and publicizing or developing relevant industries such as marine aquaculture, submarine diving sightseeing, marine tourism and the like on the basis. Therefore, the method brings great environmental, economic and social benefits, and is a cause which is very valuable and brings benefit to future generations.
