dc.description.abstractComposition and seasonal abundance of macrobenthos in Vembanad estuary (India) seems to be influenced by the density of decaying macrophytes, especially the water fern Salvinia , deposited at the bottom of the estuary at the rate of 356.76 g/m super(2), 400.6 g/m super(2) and 221.65 g/m super(2) during premonsoon, monsoon and postmonsoon respectively In dynamic areas with high oxygen level, the weed deposits were associated with high biomass of bivalves and other regions of denser weed deposits were poorer in biomass and dominated by polychaetes A steady long term increase in the abundance of amphipods attaining the highest density of 70.290/m super(2), seems to be partly due to the progressive ingression of exogeneous macrophytic biomass The possible role of cumulative deposition of macrophytic biomass in bringing about a gradual alternation in the estuarine benthic communities and its significance in the food chain is discussed.
