Penaeid Prawn Welfare: Comprehensive Water Quality Management

Comprehensive water quality management is the foundation of penaeid prawn welfare, with multiple parameters requiring simultaneous monitoring and control.

Key Facts

Optimal salinity for whiteleg shrimp is 15-25 parts per thousand
Temperature should remain between 23-30 degrees Celsius for optimal welfare
Dissolved oxygen should exceed 5 mg/L; welfare impairment occurs below 3 mg/L
Total ammonia nitrogen should remain below 0.5 mg/L to prevent stress
pH should remain between 7.5-8.5 for optimal welfare outcomes

Welfare Considerations

Penaeid prawn welfare is directly determined by water quality across multiple simultaneous parameters. Deviation from optimal ranges in any parameter causes physiological stress. Compounding suboptimal parameters creates additive welfare harm. Comprehensive water quality management requires continuous monitoring, rapid response to parameter deviations, and understanding of parameter interactions. Welfare-focused water quality management maintains all parameters within optimal ranges simultaneously, not just preventing acute mortality. The investment in water quality monitoring infrastructure provides immediate welfare benefits and reduces disease-related production losses.
