Effects of Solar Eclipse on Zooplanktomic Diel Periodicity and Primary Productivity in fresh water ponds

Abstract

Solar eclipse was observed to initiate changes in primary productivity and diel periodicity in zooplanktonic surface crowding. Eclipse effect was more pronounced on loricate, illoricate rotifers and a copepoda Mesocyclops leukarti. Total and partial eclipse were observed to have certain differences in bringing about changes in zooplanktonic diel periodicity. Total solar eclipse at the early or later part of the day might have different impact on fresh water biota.
