Studies on the Macro-Invertebrate Diversity of Some Ponds at Paschimpara Village, Goghat, Hooghly, West Bengal

Three years periodic surveys on macroinvertebrate diversity in several ponds at Paschimpara village of Goghat-II Panchayat under Arambagh sub-division, Hooghly district, West Bengal, have revealed that chironomid larvae are dominated in polluted pond, while odonate larvae were abundant in almost all the ponds. In the beginning of this study a poriferan species Spongilla carteri was observed to flourish in these ponds but later the population of Spongilla carteri is almost vanished in most of the ponds which are particularly in the middle of agricultural fields. Modern agriculture highly depending on inorganic manure and insecticide might have possibly affected the invertebrate diversity of the pond ecosystems that play a vital role in village life and these ponds need to be conserved from chemical pollution. In the present paper macroinvertebrate diversities of these pond ecosystems are recorded and discussed along with some physico-chemical parameters.
