Abstract

Commercial aquaculture continues to expand as it strives to meet growing global demand for healthier protein. In this context, farmers are under great pressure to address problems of biofouling and predation, all while reducing operational costs and losses. Copper alloy mesh (CAM) has been shown to provide solutions to these problems, yet there has not been an in-depth study of economic benefits of adopting this new technology. This study was conducted in Chile using one 2010 grow-out cycle of trout (Oncorhynchus mykiss) and combined productivity indicators with economic analysis based on investment theory. Results showed that CAM net yielded better productivity indexes and higher net economic benefits than those of nylon net with anti-fouling coating. Sensitivity analyses showed a greater effect on the profitability of nylon versus CAM and a reduced elasticity of pen profitability with respect to the rental cost of CAM.
