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
  • 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
