Farm Animal Welfare

Farmed Tilapia Heat Stress and Climate

Tilapia are warm-water fish but face heat stress at extreme temperatures - climate change is pushing optimal ranges in some production regions.

Key Facts

Tilapia thrive between 25-30 C but show stress above 35 C
Tropical pond farming faces increasing heat stress events with climate change
Aeration and water exchange help manage temperature extremes in pond systems
Genetic selection for heat tolerance is emerging as a breeding priority
RAS systems provide temperature control independent of climate conditions

Welfare Considerations

Climate change is shifting the welfare calculus for tilapia farming in some regions. Heat stress causes real physiological harm. Farm adaptation through aeration, shade, and ultimately RAS systems protects fish welfare from worsening climate extremes.

What You Can Do

Support aquaculture research into climate-resilient tilapia farming systems
Advocate for climate adaptation planning in aquaculture welfare frameworks
Choose tilapia products from farms with documented water quality management
