Abstract
The extracellular metabolites of planktonic bloom dominant algae play a most significant role in the determination of bloom sequence in a eutrophied freshwater pond. Certain extracellular metabolites of planktonic blue-green algae substantially inhibit the growth of planktonic diatoms in culture and in the natural sequence in Linsley Pond. Preliminary tests indicate that the inhibition of diatom growth by blue-green algal metabolites may be widespread in freshwater lakes. When the elimination of excessive nutrient inflow is not practical, biological management, or programming, of blooms in eutrophied lakes should be attempted. An hypothetical plan is offered to modify the unsatisfactory conditions in one lake which would cost approximately $500 per annum while providing a more satisfactory lake from both aesthetic and food chain points of view.
