Safety through technology
Closed structures in plastic, concrete or fiberglass are evolving. These can be closed flexible bags or stiffer structures, and liceskirts mounted on the upper part of the fish net. The purpose of floating closed fish cage systems is to preserve the environment around the sites, control the water quality of the water and prevent lice from spreading. Closed systems change the physic of the structure. Forcing the water to flow around and underneath the structure, instead of flowing through as for traditional fish nets.
