Özet

In the present study, innovative and environment friendly copper alloy mesh material was used in an offshore cage system to compare with traditional nylon nets, in a one-year grow-out cycle of European seabass (Dicentrarchuslabrax). Based on combined indicators such as growth performance, feed utilization with bio-economic assessment of initial investment costs, it was observed that copper alloy mesh performed higher productivity indices and economic benefits compared to those in the antifouling coated traditional nylon net pens. Results showed that copper alloy mesh is a promising alternative material that could be used in offshore cage aquaculture with an improved economic return.
