The expansion of aquaculture in marine environments is reaching new heights thanks to innovative technological advances that enable sustainable and larger-scale fish farming. This study, conducted by the AquaWind project, has examined the performance of a prototype sea cage specially designed to integrate with offshore renewable energy platforms, compared to the performance of a conventional commercial cage. This innovative experimental design focused on rearing Sparus aurata (sea bream), a widely farmed species, in a completely new and controlled environment.
The experimental cage incorporates a copper alloy netting and features remote monitoring systems, which allow real-time monitoring of environmental conditions and fish welfare. During 42 days of testing, the researchers evaluated fish growth, biochemical indicators, and general health status compared to those in the conventional cage. The results show that automation and remote control of offshore aquaculture farms are not only possible but also effective in achieving sustainable levels of production. However, experts stress the importance of further refining cage design and optimising feeding strategies to maximise yield and further reduce environmental impact.
This study represents a crucial step in the development of aquaculture solutions that combine technology and sustainability, offering an encouraging outlook for the future of the fishing industry and the responsible use of marine resources.
