Over longer periods and based on earlier stage lessons, considerable structural and operational responses may be required, as outlined in Table 1.17. Genetic knowledge and management is likely to be more critical, including genetic improvement for more efficient feeding and diet specificity, and improved species resistance to wider temperature ranges, salinity changes, lower oxygen and to a wider range of pathogens. New aquatic pathogen risks may require biosecurity and prevention measures to be more closely applied (Gatesoupe, 2009).
