Whole-lake N fertilization did not prevent the summer blue-green algal blooms in Indian Lake. Low DIN apparently does not trigger the bloom development or cause the vernal nonblue-green algae to decline. Also, Sow total N:P ratios (<11 by weight) during the blooms occur partly because of...
PROBLEM TO BE SOLVED: To control green algae by readily and efficiently exterminating blue - green algae using a compound having photosensitivity and to prevent the environmental pollution due to development of harmful blue - green algae.;SOLUTION: The green algae inhibitor comprises a cationic porphy...
This paper investigates the effect of lake mixing, due to artificial hypolimnetic aeration, on the succession and ecological composition of selected phytoplankton species in Tegeler See, Berlin. Special attention is given to Microcystis , a nuisance bloom-forming blue-green algae and its competitor (...
