The protection cage from a mass mortality by red tide and a dead loss of farming fishes by the waves

摘要

The present invention relates to an offshore cage fish farm.;Marine cage farming suffers huge losses when red tide occurs due to the lack of proper methods or facilities to isolate the fish from the red tide, or the damage to the cages caused by the rough waves. When red tide occurs, it sprays red sea on the nearby sea to reduce the damage of red tide, but there is no suitable alternative except waiting for the red tide to survive by itself. Also, cages are always exposed to rough waves, but there are no facilities or methods to protect them. In addition, the red tide floats in a large amount in the surface layer of 1 to 2 m, making the surface layer into an oxygen-free red tide layer.;Cage cages can block nets to prevent fish from reaching the red tides. The cage can be submerged in water to prevent the killing of farmed fish. It also protects the cage from strong waves and can prevent the loss of fish.;Cage cage is designed to secure strong structural strength by combining the properties of steel wire and the structural principle of planar lattice. The cage is protected by using a steel wire and a stainless steel strip as horizontal and vertical members, respectively, to make a large flat grid, and then to form a flat grid or circle, and to install a cage inside. Cage cages are strong in impact resistance, lightweight, and easy to assemble and install.;The cages will be a good resource to prevent the killing of farmed fish from red tide and to protect the cages from violent waves.;Red tide, red water, sea cage culture, cage net, cage cage.
