Abstract

Benthic macro invertebrate species are differentially sensitive to many biotic and abiotic factors in their environment. The field BIOTIC INDEX (Hilsenhoff, 1988) is based on family level identification of water arthropods, amphipods and isopods. An interest in environmental quality is one of the major reasons for the study of AQUATIC INSECTS.The idea of using the aquatic insect community to "indicate" the degree of purity or pollution of a body of water is over half a century old. It is based on the concept of indicator organisms and tolerance levels. During 2004-2005, studies were carried out on the field BIOTIC INDEX of SHAPOOR RIVER in Kazeroon region (South of Iran) by using aquatic insect's fauna. A total of 34 families were collected and identified in 27 habitat code of SHAPOOR RIVER. Then use the Hilsenhoff formula for BIOTIC INDEX (BI): BI=S ni ai/N where nj is the number of specimens in each taxonomic group (family), ai is the pollution tolerance score for that taxonomic group, and N is the total number of AQUATIC INSECTS in sample. AQUATIC INSECTS are given a numerical pollution tolerance score (ai) ranging from 0 to 10 (Hilsenhoff, 1987). The value is based on field and laboratory responses of these organisms toward organic pollution. Zero taxa are extremely intolerant of low dissolved oxygen; taxa with score of 2 through 9 are tolerant to varying degrees; taxa wich can survive great amounts of pollution are scored 10. In this survey, BIOTIC INDEX of SHAPOOR RIVER were 3.79 and evalution of the WATER QUALITY based on the BIOTIC INDEX were calculated. WATER QUALITY of SHAPOOR RIVER were very good (possible slight organic pollution) during of this survey.
