Abstract

Shrimp fanning industry has rapidly expanded in the south of Iran especially in Hormozgan Province over the past decade. In 2001, nitrate, nitrite, ammonia, total inorganic nitrate, reactive phosphate and total phosphate were assessed monthly in Tiab creek to evaluate the environmental effects of the industry. During the study period, nitrate varied between 4.06-23.58pm/1 where as variation for nitrite was measured as 0.21••2.23im11. Variation for ammonia was 0.07-2.04m/1, for total inorganic nitrate was 4.46•w25.131.imi1 and for reactive phosphate and total phosphate were 0.114m2.35irill and 1.3-22.731/m11 respectively. Results of this study showed that concentration of nutrients in the outlet effluents and creek mouth were higher than other stations. Also, comparison of concentration of nutrients between stations showed that there were significant differences between effluent water and other stations (P<0.05)......
