Liming and Fisheries Management Guidelines for Acidified Lakes in the Adirondack Region.

Liming is the general term used for the addition of base neutralizing materials to acidic waters and soils. Various base-containing materials may be used, but limestone calcium carbonate, CaCO3 is predominate in the major surface-water liming programs in the United States, Canada, and Scandinavia Fraser and Britt 1982. Liming, in fact, has long been used to increase fish productivity in softwater and acidic ponds, lakes, and streams e.g., Neess 1949, Hasler et al. 1951, Waters 1957, Boyd 1982.
