SUGGESTIONS FOR IMPROVEMENT Feed conversion rates, protein level in the feed, and Protein level in the fish should become available at least for the main species in aquaculture and key culture systems. Critical levels should be set where possible (but effects of nutrients are very site specific). In the future the indicators could encompass the rest of aquaculture related pressures into the environment such as escapes and increases in pathogen density, chemotherapeutants and antibiotics, increased demand for feed inputs, interactions with the seafloor (sediment quality and effect on benthos), non‑native species. Extension to other aquaculture other than finfish.
