A long-overlooked population
Fish and other aquatic animals are among the animals most intensively used by humans and among the least visible in law and public debate. Welfare guidelines are therefore an important step: they acknowledge that these animals can be harmed by handling, crowding, transport, disease, water quality, slaughter, and confinement.
Recognition, however, should not be confused with resolution. A guideline can improve some practices while leaving the basic conditions of industrial exploitation unquestioned.
The question welfare must confront
A serious discussion of aquatic welfare must ask whether the animals' biological and behavioural needs can be met within systems designed to maximise production. It must also include species whose suffering has been treated as negligible because it occurs underwater and out of sight.
The challenge is to make welfare more than a technical label: it should become a demand for legal, institutional, and economic practices that take aquatic animals' lives seriously.
