Description

{SYSTEM FOR PROTECTING FLOATING FISH CAGE}

The present invention relates to a cage farm protection system.

Generally, in coastal waters, aquaculture using a cage culture farm in which a net is hung from a cage to cultivate fish and shellfish inside the net is actively carried out. These cage farms are designed to allow a large amount of fish to be easily cultivated in one place by preventing the fish and shellfish from escaping to the outside by the net hanging from the cave.

Caged fish farms produce a large amount of fish and shellfish in a limited space, contributing greatly to the increase in income of fishing villages, or red sea or green algae (hereinafter referred to as "harmful algae") occurring in coastal waters, The damage has been causing a great deal of damage.

As a reference, red tide is caused by eutrophication of the coast due to environmental pollution. When the red tide occurs, the viscosity of seawater increases due to the mucous substance secreted by phytoplankton, and it becomes difficult for fish and shellfish to float. It can also block the nerve and paralyze the nerves, which can kill a large amount of fish.

In addition, when phytoplankton is killed by microorganisms, oxygen dissolved in seawater is consumed and dissolved oxygen becomes insufficient, so fish can be killed by respiratory disorder.

As such, harmful algae such as red tide and green tide cause fatal consequences to marine life and freshwater creatures, so that efforts are being made to prevent harmful algae in the world. For example, when red tide occurs, The red tide has been removed by spraying it on the surface of the sea and immersing it in water.

However, the conventional method as described above can not prevent the harmful alga occurring in a wide area at a time, and it can not prevent the harmful alga that has already occurred from penetrating into the cage farm, I have a problem that I can not.
