Freshwater biology is the scientific biological study of freshwater ecosystems and is a branch of Limnology. It seeks to understand the relationships between living organisms in freshwater and their physical and chemical environment. The discipline is also widely used in a number of industrial processes such as sewage treatment[1] and water purification which utilise biological processes to effect purification.
In the UK, a leading organization promoting and practising freshwater biology is the Freshwater Biological Association[2] based near Windermere in Cumbria.
