A recent study reveals that fish, including rainbow trout, experience intense pain for several minutes when killed using common methods like air asphyxiation. This suffering extends beyond slaughter, with pre-slaughter stressors also contributing to their distress. Researchers suggest improved stunning methods and worker training to reduce fish suffering and promote more humane practices in fish farming.
