    Brief

    This opportunity seeks specialized expertise in captive rearing of juvenile freshwater pearl mussels, a highly technical and critical conservation activity. Rearing requires advanced technical knowledge, meticulous attention to detail, and strictly controlled water quality management. This service is not commercially available, with only three active hatcheries in Britain currently performing this work: the Freshwater Biological Association (FBA), the Environment Agency's Kielder hatchery, and Natural Resources Wales's Clywedog hatchery. Similar facilities operate in Ireland, France, Norway, and Luxembourg. Suppliers should have demonstrable experience in freshwater pearl mussel propagation, larval rearing protocols, and the maintenance of specialized aquaculture infrastructure to support this conservation breeding program for the Afon Irfon and River Dee populations.
