Welfare indicators
Research on fish suffering during slaughter relies on measures to indicate when fish are conscious and experiencing pain. Some indicators used by welfare studies include
- Behavior
- Swimming, gill movement, eye movement in response to body reorientation, reaction when turned upside down, etc.
- Electrical measures
- EEG, ECG, evoked responses, etc.
- These are quite accurate but also require high levels of expertise.
- Haematic measures
- Cortisol, plasma glucose, plasma lactate, haematocrit, etc.
- Tissue measures
Inhumane methods
Air asphyxiation
Ice bath
CO2 narcosis
Potentially more humane methods
Percussive stunning
Spiking
Electrical stunning
Current research
Regulations
- UK law?
- EFSA
