Occurrences, abundance and seasonal distribution of
the benthic fauna of the mudbank area at Alleppey
were investigated. Ihe substratum at the mudbank area
being of an unconsolidated and unstable nature due
to the fresh supply of sediments and their periodic
movement, it was thought that the fauna therein may
be of a recent colonisation and a study on the animal-
sediment relationship would be of interest. This
was well established during the present studies with
regard to the occurrence and numerical abundance of
species and the benthic population in general
