Abstract |
Plantonic herbivores controlled the growth of phytoplankton in the open waters of Southern Lake Huron during the late summer and fall; larger algae remained untouched during the spring diatom bloom. Over a growing season these crustaceans grazed 0.3 to 41.9% of the standing crop of phytoplankton. Immature copepods (nauplii and copepodites) were the most effective grazers. Selective grazing by crustaceans centered on nannoplankton (less then 22 micrometers), whereby 92 to 2804% of the daily productivity was grazed by large cladcerans and immature copepods. In contrast, netplankton was harvested to a much lesser degree. Laboratory experiments reinforced this picture of selective cropping. Presently in Lake Huron such selective grazing accounts for an effective biological control over algal production. |
