ABSTRACT:
This invention relates to the selective control of algae in ponds, sewage lagoons, cooling towers, lakes, and other bodies of water, including managed bodies of water, and deals particularly with the use of certain long-chain fatty acids and salts thereof for chemical control of Cyanochloronta (blue-green algae). Stimulation of Chlorophycophyta (green algae) is achieved by the use of one embodiment of this invention.
Application of the invention to bodies of water used in aquaculture eliminates earthy, musty flavors and other disagreeable flavors associated with blue-green algae in fish and other cultured organisms. Furthermore, a more balanced diversity of planktonic organisms can be maintained which makes oxygen depletion problems more manageable.
