The mussel spends its larval, or glochidial, stage attached to the gills of salmonid fishes. In contrast, one of the largest species of freshwater bivalves is the swan mussel, in the family Unionidae; it can grow to a length of 20 cm, and usually lives in lakes or slow rivers. It is a moderately large river with nutrient conditions that range from oligo-mesotrophic to mesotrophic. Garndolbenmaen Weir on the Afon Dwyfor is used by NRW for flow gauging.

Eggs incubate and hatch into microscopic mussel infants – called glochidia – which need to attach themselves to the gills or fins of a passing host fish. Ecology of the Freshwater Pearl Mussel 1 Conserving Natura 2000 Rivers This account of the ecology of the freshwater pearl mussel (Magaritifera margaritifera) has beenproduced as part of Life in UK Rivers– a project to develop methods for conserving the wildlife and habitats of rivers within the Natura 2000 network of protected European sites.The project’s focus Scotland holds some of the largest known remaining populations. The freshwater pearl mussel is one of the longest-lived invertebrates known, and can live for more than 100 years. Freshwater mussels have a unique lifecycle. The decline in pearl mussel populations is due to a number of factors: protected under both UK and European legislation. The Scottish Biodiversity List is a tool for public bodies and others doing their Biodiversity Duty. It is a moderately large river, being ultra-oligotrophic in its upland reaches within the Republic of Ireland, before gradually becoming oligotrophic and oligo-mesotrophic through its middle and lower reaches within Northern Ireland. to survive as adults. Eight of these populations contain 80% of the total Irish freshwater pearl mussel population, and are known as the ‘Top 8 catchments'.
