Description

Marine ecological aquaculture net cage

Technical Field

The utility model belongs to the technical field of ecological breeding, and particularly relates to a marine ecological breeding net cage.

Background

At present: the sea is a blue granary for acquiring high-quality protein by human beings. In recent 40 years, the marine fishery with seawater culture as the key point in China has rapidly developed, five industrial waves for culturing seaweed, marine shrimps, marine shellfish, marine fish and seafood are raised, and the total culture yield is stable in the first place in the world since 1990. Meanwhile, the problems of deterioration of local water area environment, decline of product quality and serious culture diseases become more serious day by day, and the traditional mode of mariculture is difficult to adapt to the requirements of healthy development of economy and society and current situation of marine ecological environment in China.

The existing marine culture mode can cause the problems of culture excretion waste, leakage of residual bait, serious water eutrophication and the like.

Through the above analysis, the problems and defects of the prior art are as follows:

(1) the existing ecological aquaculture net cage is not enough for protecting ecological environment and treating organic waste, and is mostly concentrated on the safety of the net cage in strong wind and strong wave environment, the convenience of the use of the net cage and the safety of users.

(2) The existing marine culture mode can cause the problems of culture excretion waste, residual bait leakage, serious water eutrophication and the like

The difficulty in solving the above problems and defects is: the physical and chemical repairing cost is high, and strong impact is generated on the economic benefit of the breeding industry.

The significance of solving the problems and the defects is as follows: through biological-ecological measures, the damaged marine ecosystem caused by cultivation is repaired, the material circulation and the energy circulation of the ecosystem are accelerated, the yield and the quality of mariculture are increased, and the sustainable development of mariculture is realized.

SUMMERY OF THE UTILITY MODEL

Aiming at the problems in the prior art, the utility model provides a marine ecological aquaculture net cage.

The utility model is realized in such a way that the marine ecological aquaculture net cage is provided with:

an inner net cage and an outer net cage; the inner layer net cage and the outer layer net cage are connected by a wood layer pedal, so that the net cage structure can be reinforced when the feeding personnel feed fishes conveniently. The supporting frames with strong buoyancy are annularly arranged on the inner net cage and the outer net cage, so that the upper parts of the net cages can well float on the water surface and are connected with the wood floor pedal, and feeding personnel can conveniently feed and observe the breeding condition.

The outer net cage is sleeved outside the inner net cage; a fish culture area is arranged in the inner net cage, and an algae culture area is arranged in the outer net cage.

Further, the inner net cage and the outer net cage are both of a net structure.

By combining all the technical schemes, the utility model has the advantages and positive effects that: the utility model adopts a double-layer net cage structure, the inner layer net cage is used for culturing animals such as fishes, the outer layer net cage is used for culturing submerged algae plants, the simultaneous culture of the fishes, the animals and the algae plants is realized, the algae plants are used for absorbing excrement and leaked baits of the inner layer net cage animals and are also used as feeds of the algae plants, the cost is saved, a good ecological mode is established, an ecological culture method is adopted, the water body is protected, the environmental pollution is reduced, and the material with strong buoyancy and seawater corrosion resistance is adopted, so that the service life is long and the safety is high.

Drawings

Fig. 1 is a schematic structural diagram of a marine ecological aquaculture net cage provided by the embodiment of the utility model.

In the figure: 1. an inner layer net cage; 2. an outer net cage.

Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention is further described in detail with reference to the following embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the utility model and are not intended to limit the utility model.

Aiming at the problems in the prior art, the utility model provides a marine ecological aquaculture net cage, which is described in detail below by combining the attached drawings.

As shown in fig. 1, the marine ecological aquaculture net cage provided by the embodiment of the utility model comprises an inner layer net cage 1 and an outer layer net cage 2; the outer net cage 2 is sleeved outside the inner net cage; a fish culture area is arranged in the inner layer net cage, and an algae culture area is arranged in the outer layer net cage. The inner layer net cage 1 and the outer layer net cage 2 are both net structures.

When the utility model is used, the inner net cage 1 is used for culturing fish and other animals, the outer net cage 2 is used for culturing submerged algae plants, a double-layer net cage structure is adopted, the fish animals and the algae plants are cultured simultaneously, and the excrement and the leaked bait of the inner net cage animals are absorbed by utilizing the enrichment and degradation of the algae plants on organic compounds, thereby realizing the purification effect on the water eutrophication caused by culture. The cost is saved, a good ecological mode is established, an ecological culture method is adopted, the water body is protected, and the environmental pollution is reduced. The supporting frame with strong buoyancy is arranged under the annular structures of the inner net cage and the outer net cage, so that the upper part of the net cage can well float on the water surface, the upper layer structure of the net cage is used for the breeding personnel to walk to observe the breeding condition, the railing is used for protecting the safety of the breeding personnel, and the lower layer structure of the net cage is in seawater and is used for breeding fish and algae. The inner net cage support frame and the outer net cage support frame are connected by using the wood layer pedal, so that the overall structure of the net cage can be stabilized, and the walking of a feeder is facilitated, fishes are fed and the culture condition is observed. Meanwhile, the whole net cage is made of a material with strong corrosion resistance, so that the service life of the net cage structure is prolonged.
