Shrimp farming industry has rapidly expanded in south of Iran in particular Hormozgan province along the coast during the decade. The aim of this study was to determine the environmental impacts of shrimp culture effluent on coastal water and creeks in Tiab area during one year (2000-2001) have been done. Many factors, including water temperature, dissolved oxygen, pH, salinity, B.O.D, nitrate, nitrite, ammonia, total inorganic nitrogen, total phosphorous, Phosphate, T.S.S, organic carbon, total organic mater,grain size of sediments,chlorophyll a, phytoplankton, zooplankton, macrofauna, miofauna and biomass,were measured in his research. The result of this study showd that concentration Nutrients in outlet effluents and cereeks mouth were higer than other stations. Also comparison of concentration of nutrients in mouth creeks, inlet Chanel and outlet Chanels showed that there was significant diffrence between effluent water with other stations (P<0.05). 58 genera to 3 families of phytoplankton , 12 groups of zooplankton , 8 groups of macrofauna and 9 groups of meiofauna were identified this investigations. The Result of biological parameter (phytoplankton, chlorophyll a, macrofauna and miofauna showed that diversity and density considerably decreased in outlet Chanels and mouth creeks.Pages
