The report describes the effects of copper sulfate (CuSO4.5H20) on certain algal and zooplankton populations in Winnisquam Lake, New Hampshire. The bloom alga was Anabaena circinalis and it was controlled by an application of four pounds of copper sulfate per surface acre. The cell numbers of 27 species of the algal community were recorded before and after copper sulfate treatment. The carbon fixation rate was found to be a more sensitive measure of bloom potential than were cell counts. Copepods and Bosmina longirostris were more resistant to copper sulfate than were Daphnia. After copper sulfate application Bosmina multiplied to a concentration of 154 per liter in the top meter of the water column. (Author)
