Scientific research into fish stunning is advancing rapidly, providing the technical foundations for more humane fish slaughter practices in aquaculture and wild fisheries.
The science of fish stunning has progressed sufficiently to provide industry with viable, scalable alternatives to inhumane killing methods. Electrical stunning at appropriate voltages and frequencies renders fish instantaneously unconscious without pain. Percussive stunning, if applied to the correct cranial location with sufficient force, causes immediate loss of consciousness. The challenge is ensuring consistent application in commercial settings and developing appropriate monitoring for stunning effectiveness. Consumer and retailer demand is increasingly driving industry adoption of improved methods.
