Farm Animal Welfare

Farmed Salmon Brain Welfare Advanced

Understanding salmon brain function and consciousness is essential to improving welfare in the world's largest cold-water aquaculture industry.

Key Facts

Salmon have a telencephalon that differs structurally from mammalian cortex but functions in learning and memory
They demonstrate anticipatory behaviour, conditioned place preference, and avoidance learning
Chronic crowding and handling induce lasting changes in stress axis sensitivity
Pain processing in salmon involves peripheral nociceptors and central sensitisation
Welfare assessment tools based on cognitive and affective indicators are being developed for salmon

Welfare Considerations

Salmon brain science confirms that welfare cannot be dismissed on the basis that fish 'just don't feel pain'; the question is not whether salmon suffer but how to reduce it.
