Marine fouling is driven by sunlight and high water temperatures. Therefore, the waterflow through the cages and oxygen level will be reduced. Strong algae growth causes the cage/net to become heavier, which causes stress and in the worst case scenario a breakdown of the cage construction. This in turn increases the risk of fish escape. The algea growth could also cause disease and stress symptoms in the biomass. With AKVA group´s net cleaning equipment the fish in the location will prosper in optimum growth conditions.
