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 Idema quality Net Cleaning equipment the fish in the location will prosper in optimum growth conditions.
