Study On The Macrobenthie Structure of Bamdezh Wetland

In this study , the composition and diversity of the invertebrates of Bamdezh Wetland were studied for determining biotic index . According to the result of this research , 6 class of the freshwater benthic invertebrates were recorded in this region. The most abundant class during two period of sampling was the gastropoda( 69.30%). For evaluating biodiversity of macrobenthics in this region , Shanon and Sympson Index were used The maximum value of Shanon and Sympson index were recorded 2.37 & 0.97 and the minimum value were recorded 0.45 & 0.11 respectively . For indentification, separation and diversity determination of Macrobenthics, 3 samples of sediment were gathered by 0.025m Van Veen garb
