Macrozoobenthic Community as Biological Indicators of Pollution in river Jhelum, Kashmir
Journal Title: Universal Journal of Environmental Research and Technology - Year 2012, Vol 2, Issue 4
Abstract
A detailed limnological study of the River Jhelum, Kashmir was conducted during February 2011 to July 2011. Six study sites were selected for the collection of samples. The physico-chemical parameters of water and population density of three phyla viz, Arthropoda, Annelida and Mollusca were determined. The ionic composition of water of the River varied in close relationship with the catchment pattern of the concerned water body. The River Jhelum receiving all sorts of allochthonus material from the catchment had the highest conductivity. The water of the River was well buffered with pH > 7. A total of 21 taxa of macrozoobenthos were recorded from the system. Arthropoda was most dominant group constituting 54.7%, followed by Annelida 28.9% and Mollusca contributed 16.4% of total macrozoobenthos . The hard and stony bottomed sites were dominated by insects belonging to orders Ephemeroptera, Tricoptera and Diptera. Significant changes in macrozoobenthic communities were primarily due to changes in water quality. As elsewhere, macrozoobenthic communities proved to be good indicators of water quality and should be used as bioindicators in long-term monitoring of this river.
