Abstract: (3806 Views)
One of the most important issues in environmental management of coastal waters is the evaluation of Eutrophication. In this study, the trophic status of coastal waters of Hormozgan province was evaluated using Scale (TRIXCS) and Unscale (UNTRIXCS) trophic indices in 2012. The results showed that TRIXCS values were in the range of 3.6 to 5.9 (in the area 1 Mezo-Eutroph, areas 2 and 3 Mezotroph, and area 4 Oligo – Mezotroph) and UNTRIXCS values ranged from 3.4 to 5.8 (no risk in the 4th area and high risk in other areas). Based on the results of TQR trix index, the status of eutrophication in areas 1, 2 and 3 was in good status, while area 4 was in very good status. The coefficient efficiency trophy index was 4.92±0.03, suggesting that the amount of nutrients consumed by phytoplankton near shore of Bandar Abbas (in area 1) was higher than other areas. Altogether, according to comments and suggestions by many scientists, trophic state Scale (Trixcs) index can be used for evaluation of eutrophication in coastal waters, after revisiting and development.
