Tilapia Welfare During Production System Transitions

Transitioning tilapia between production stages involves welfare challenges from changes in water quality, density, feeding, and social conditions.

Key Facts

Tilapia production involves multiple transitions from hatchery to nursery to grow-out
Each transition involves transport stress, new environmental conditions, and social disruption
Acclimation periods following transfer reduce acute stress responses
Water quality parameters should be matched between source and destination systems
Gradual transitions with buffer periods reduce welfare costs compared to abrupt transfers

Welfare Considerations

Welfare challenges peak during production system transitions in tilapia farming. Each transfer exposes fish to crowding, handling, and new environmental conditions that trigger acute stress responses. Poor transition management causes elevated post-transfer mortality and disease susceptibility. Welfare-conscious transition management includes gradual temperature and salinity acclimation, minimising crowding duration, and providing adequate recovery time before the next stressor. Transition protocols that treat welfare as a production parameter reduce both welfare costs and mortality losses.
