The cage shown in the photo is a unit of a cage farm suited in Black Sea (Turkey). The water depth at this location is about 50 meters. The cage diameter is 30 meters with a volume of approximately 10,000 m3. Fish biomass of each cage is about 110-130 tons. The mentioned farm consists of ten cages and hence the target production is about 1000 tons of European seabass/year. This particular farm has four of those cages at the moment and plan to establish five more cages in two years reaching 10000 tons/year of fish biomass as a total production capacity.
