Red Drum Welfare in Aquaculture

Red drum (Sciaenops ocellatus) is an increasingly important aquaculture species in North America whose welfare needs require greater attention.

Key Facts

• Red drum is farmed in pond and tank systems in southern US states and internationally
• It is an active, predatory species that requires adequate space and water quality
• Crowding stress causes immunosuppression and disease vulnerability in farmed red drum
• Red drum are sensitive to low dissolved oxygen and temperature extremes
• Welfare during harvest including crowding, aerial exposure, and slaughter is largely unaddressed

Welfare Considerations

Red drum welfare in aquaculture deserves attention as production scales up. These active, predatory fish experience welfare harms from overcrowding, poor water quality, and inappropriate handling during harvest. Chronic crowding stress elevates cortisol and compromises immune function, increasing susceptibility to bacterial and parasitic disease. Welfare-conscious red drum aquaculture requires adequate space allowances, optimal dissolved oxygen management through aeration, temperature monitoring during seasonal extremes, and the adoption of humane slaughter methods. The welfare of red drum during harvest — including crowding, aerial exposure during netting, and slaughter by suffocation or ice slurry — requires urgent improvement.

What You Can Do

• Support aquaculture welfare labeling that includes species-specific welfare standards for red drum
• Advocate for pre-slaughter stunning as standard practice in red drum aquaculture
• Encourage dissolved oxygen and temperature monitoring as welfare compliance requirements
• Support research into red drum-specific behavioral and physiological welfare indicators
• Choose seafood certified by programs that include fish welfare criteria
