Abstract
In Hooghly estuary the incidence of oligochaetan worm, Limnodrilus hoffmesteri, has been observed (October 2006-November 2008)in two studied stations. One of which was linked with more discharge of factory effluents Rishra (station -A) and other was Panihati (station -B)with minimum pollutant exposure. The said oligochaetan population appeared in vigor number at station -A and very minimum number was seen at station -B. The station -A presented silty soil enriched with organic carbon and the water body of the said station was marked with low dissolved oxygen and high alkalinity. This situation confirms the specimen to be a pollution indicator denoting the stress situation of the Hooghly estuarine ecosystem. © Global Science Publications.
