Sediments were sampled from three different point of 9 ponds by grab (Van Veen 0.02 m2) for identification macrofauna, miofauna, grain size and mesurment of total organic mater. Macrofauna benthics were few and were found only in three ponds. Three groups of miofauna including: Nematoda, Naplius and copepoda were distinguished. Their abundance was increased during main shrimp culturing period and was decreased at the end of it. Silt was the main part of soil in most ponds.
