Description

Marine artificial forest grazing and fishing ground

The invention relates to a pasture and fishery, in particular to a marine artificial forest pasture and fishery which can provide a good growth environment for marine organisms.

With the continuous advancement of human science and technology, the marine ecology is constantly being destroyed. For example, industrial waste water is discharged into the ocean, causing seawater pollution. Fishermen use gillnets to catch all fish, large and small, or use bombing methods to make the fishing sites Fisheries in the nearby waters cannot survive, causing damage to the natural ecology of the ocean. In addition, in the cultivation of fish stocks, the general saltwater aquaculture industry usually reclaims fish farms near the sea and diverts seawater to breed saltwater fish. However, the breeding range of fish farms is relatively small, and there are still the following disadvantages in farming technology:

1. Deposition of sulfide (CyanogenSulfide):

The excreta produced by fisheries are organic pollutants, and the sediments of organic pollutants are accumulated in fisheries and converted into sulfides. The sulfides will absorb the oxygen contained in the water and reduce the dissolved oxygen rate, which is harmful to the growth of fisheries.

2. Atmospheric pressure reduction:

Whenever the south wind blows in summer, the atmospheric pressure will drop, which will cause the oxygen in the water in the fish to volatilize, and the dissolved oxygen concentration in the water will drop to 1-3PPM. And the excrement of aquaculture species accumulates at the bottom of the pond to form sulfide, which will also float upward due to the drop in atmospheric pressure, and will absorb oxygen, thereby reducing the dissolved oxygen. Insufficient and die.

The object of the present invention is to provide a marine artificial forest animal husbandry and fishery, which can restore the natural ecology of the ocean and make it have the effect of gathering fish and cultivating.

The base is composed of more than one well-shaped frame with different sizes. These frames are gradually enlarged from the inside to the outside and do not overlap. There are a plurality of ring hooks; the artificial reefs are formed by connecting a plurality of artificial reefs in series, and the hooks are placed on the ring hooks, so that an accommodation space is formed between the artificial reefs, and the artificial reefs There are a plurality of through holes that can be adjusted to the size of the buoyancy in the ocean, and there are several connectors that can connect the uppermost artificial reef body on each frame, so as to maintain the stability of the uppermost artificial reef body.

The marine artificial forest animal husbandry and fishery of the present invention has the following advantages:

1. The breeding environment is suitable for fish growth:

Because the environment in which the ocean grows, such as water temperature, oxygen concentration, and water quality, is a natural environment, it is suitable for aquaculture fisheries, and the aquaculture fishes have natural food such as small fish, algae, and plankton. Therefore, the fish has no earthy smell, and the fish farmed in the natural environment has no drug residues, which is guaranteed for consumers, and the quality is better and the cost is lower.

2. It has the effect of gathering fish and breeding:

Because there are accommodating spaces and a plurality of through holes formed in the artificial string reef, the artificial reef body of the artificial string reef can gather food for fish schools, grow microorganisms, and have the effect of gathering fish, and the artificial string reef Reefs are connected with fishing nets, which can also form breeding farms to achieve the purpose of breeding.
