| Abstract | ||
| Aquatic insects as bioindicators and in order to determine water quality in relation to organic matters were used to evaluate the water quality of Fars Province streams and two drainages. Eighteen springs that were presumed to be undisturbed by human activities and two others, disturbed by human activities were chosen to show the effects of the pollutions. Insects fauna or each stream were sampled seasonally in a year period by D. framed aquatic net. Each species (with index value) was used for calculating the biotic index pollutants of these water resources. Water quality determined for 18 springs and two drainages, Based on these values. Chel Cheshmeh, Salavat, Shirin and streams had excellent water qualities (no organic pollution). Paeen, Tang-e-Bostanak and Kamfirooz had good water quality with possible slight organic pollution. Kavar and Barm-e-delak streams had fair water quality (significant organic pollution) and two drainages had poor water qualities (very significant and sever organic pollution). To compare the results, some physical and chemical parameters of water were measured. | ||
