Freshwater Pearl Mussel Conservation Welfare

Freshwater pearl mussels are critically endangered bivalves that depend on clean rivers and salmon host fish for their larval stage.

Key Facts

Freshwater pearl mussels are among the most endangered species in Europe
Larvae are parasitic on the gills of salmon and trout for several months
Population decline is driven by poor water quality, siltation and illegal pearling
Captive breeding programmes rear juveniles in artificial habitats for river reintroduction
Recovery depends on improving river water quality alongside direct conservation

Welfare Considerations

While the sentience of mussels is uncertain, their ecological role is profound. Conservation of this keystone species supports overall freshwater ecosystem health including fish welfare. River restoration benefits entire aquatic communities.
