Description

Combined farming methods for shellfish and algae using the structure settlement method {The combinated farming way of the fish, the shellfish and the seaweed used by fabric's sinking system}

The present invention relates to a composite culture method of fish and shellfish and seaweed using the settlement method of the structure, and in the concrete structure submerged on the seabed, put the shellfish such as sea urchin, abalone, seashell, sea cucumber, flounder, etc., and the outer structure of the upper seaweed, Seaweeds were installed at regular intervals with spores attached to the seaweeds such as seaweed and sea squirt.

In general, the marine culture is divided into sponge, middle layer, and low layer, and the marine form includes fish, seaweed, seaweed, kelp, and cages. In a farmed way, abalone plaques are stored in oysters, sea scallops, scallops, or chalongs to be hung.

In addition, low-rise farming is a method of spreading algae on the seabed so that it can grow naturally in the natural environment.

In the conventional marine culture, there are many cases in which marine or marine algae grow due to coastal pollution, red tide, white phenomena, and fisheries are lost due to typhoons, and in the case of cage farming, the marine environment is caused by residual feed and excreta. In the case of farming, the abalone plaque is farmed by the wave, and the abalone plaque is stressed and the mortality rate is high.

In addition, when spreading the plaque on the sea floor, it is eaten by pirates, so the survival rate is low, and it is not possible to leave the area to the marine environment or to adapt to the environment, and the purpose of the death is not achieved.

In addition, a submerged submerged structure, which manufactures concrete structures and submerges them on the seabed and puts abalone patches on the concrete structure, has been disclosed as Patent 2000-71944. When the plaque is farmed on the shelf, the movement distance is increased by the pressure of water and the position of the feeding is slow, and the growth is slow. When the water flows into the concrete structure and moves, the closed end of the structure is damaged due to the pressure of the algae on the shelves in the concrete structure, and in the case of overturning, it is possible to settle down, but it is necessary to supply food and contaminate the surrounding seawater. Various conditions are not satisfied.

In addition, in order to eliminate the above-mentioned wastewater, inflowing seawater to the land and farming fish and shellfish has to produce water quality and water temperature suitable for the environment, and there has been a high mortality due to disease and high maintenance costs.

The present invention is a shelf installed on the concrete structure is provided with a distribution passage of fish and shellfish and excrement and a distribution passage of algae, and an external structure to form algae to the outside of the concrete structure to attach the spores of the seaweed that is the food of the shellfish attached It aims to provide a composite farming method of shellfish and seaweed that can purify the surrounding seawater while farming algae with medallions and shellfish at regular intervals, and can provide food sources of seafood or commercialize them.
