Macro benthic fauna of two differently polluted coastal waters of Gulf of Mannar, southeast coast of India

Environmental Science 04/2012;

ABSTRACT Macrobenthic community structure of two differently polluted coastal waters
of Tuticorin was studied for the period of July 2008 to June 2009. The
station I is LWDP and station II is Threspuram. The annual mean variance
of temperature of station I and station II is 37.8 and 29.4 respectively. The
distribution of benthos was higher in station II than station I. The species
diversity is higher at station II with the value of value 3.20 in the month of
December 2008 and 2.28 in the month of March 2009 at station I. DO is
calculated in station I as 4.12 and station II with 4.60. Station I has distinguished
percentage of very fine sand. There are totally 35 species of benthic
fauna were collected during this study. The water temperature has a distinct
influence on species diversity and abundance in this study.
