Advances in fish stunning technology are making humane slaughter increasingly feasible for aquaculture operations, representing one of the most impactful current welfare improvements possible.
Fish stunning technology has advanced substantially and represents one of the most practically achievable welfare improvements in aquaculture. Norway has mandated effective stunning for farmed fish and demonstrated that commercial-scale operations are feasible. Countries and companies that continue using live chilling or CO2 exposure as primary slaughter methods do so by choice rather than necessity. Consumer pressure and regulatory requirements are the primary levers for accelerating adoption.
