Modify anti-predator nets around aquaculture systems

Background information and definitions
Anti-predator nets may be placed around fish pens or cages to physically exclude marine or freshwater mammals to reduce predation. However, such nets may entangle mammals, causing injury or death (e.g. Díaz López et al. 2007). Reducing mesh size, using stiffened or tensioned materials, and/or enclosing nets at the bottom may reduce the risk of entanglement (Kemper et al. 2003). These measures may also deter mammal predation more effectively thereby reducing human-wildlife conflict.
