ALTHOUGH the study of lake life has received -^*- considerable systematic attention by other countries, especially on the Continent and in the United States, there had been no definite institution set up for that purpose in Great Britain or Ireland until the year 1920. It remained for the War to direct attention to our lack of knowledge of British lakes and their possible economic value; and, as a direct outcome of consultations at that time, a limnological station was established in August 1920 on the river Shannon, one mile from the northern end of Lough Derg, Ireland being considered the most suitable country in which to tackle the problem on account of its valuable inland fisheries and large area of fresh water.
