The extension of animal welfare legislation to cover farmed fish is a critical development that creates legal foundations for welfare improvement.
Welfare legislation for farmed fish is at a critical juncture in many countries. The scientific recognition of fish sentience — now reflected in UK and some EU legal frameworks — creates an obligation to extend meaningful welfare protections to the billions of fish farmed each year. However, legislation is only effective if backed by practical standards, trained inspectors, and enforcement capacity. The development of enforceable, science-based minimum welfare standards for the most important farmed fish species — Atlantic salmon, rainbow trout, tilapia, carp — is an urgent legislative priority that requires collaboration between scientists, industry, and regulators.
