Aquaculture Welfare

Farmed Tilapia Stocking Aggression Advanced

Advanced management of tilapia stocking and aggression reduces welfare costs while maintaining production efficiency through evidence-based density and sex management.

Key Facts

All-male culture reduces aggressive sexual behaviour and improves growth uniformity
Stocking at higher densities paradoxically reduces individual aggressive interactions in some systems
Visual barriers in circular tanks provide refuge for subordinate fish
Automated sorting by size reduces injury from large-on-small aggression
Feeding frequency affects aggression - multiple daily feeds reduce competition at feeding events

Welfare Considerations

Advanced tilapia aggression management uses understanding of density-aggression-welfare relationships to design systems that minimise injury and stress. Evidence-based stocking strategies tailored to system geometry and sex ratio achieve better welfare than simple density reduction.
