Improvements to minimize ‘collateral damage’ could be costly yet feasible to diffuse anger promoted by environmental agencies. An obvious example might be:
1. Better positioning (where nets are placed deeper and touching the sand,
2. Leaving sufficient above-net space for surface animals to pass above);
3. Divers inspecting nets every few hours to release non sharks;
4. Tagging and releasing some sharks except the meshing net principle is, trapped, struggling or dead sharks warn other sharks to stay from danger (they are not stupid).
