Native oyster restoration projects in UK waters are recovering populations lost to disease and over-harvesting. Welfare of restored populations requires consideration alongside conservation goals.
Native oyster restoration involves reintroduction of juvenile oysters to suitable habitat, with welfare considerations during collection, transport, and settlement. Exposure to air during tidal cycles is natural but prolonged aerial exposure during transport causes stress. Water quality at restoration sites determines long-term welfare and survival of established populations. Applying precautionary welfare standards to oyster handling during restoration operations maintains consistency with emerging bivalve welfare science.
