Abstract

The study was to investigate species composition and biological water quality of benthic macroinvertebrates among localities at Gwangseok stream, Jinhae city in Korea. The identified benthic macroinvertebrates were 781 individuals belonged to 19 species, 14 families, 8 orders, 5 classes and 3 phyla. The value of dominance index (DI) was varied from 0.184 (St. C) to 0.333 (St. A) with a mean of 0.235. DI was significantly different among the four regions. Beck-Tsuda's Biotic Index (BI) was varied from 7 (St. D) to 20 (St. C) with a mean of 14. Total ecological score of benthic macroinvertebrate community (TESB) was varied from 12 (St. D) to 38 (St. B) with a mean of 26.3. Average ecological score of benthic macroinvertebrate community (AESB) was varied from 1.714 (St. D) to 1.900 (St. B) with a mean of 1.821. Benthic macroinvertebrate index (BMI) ) was varied from 22.354 (St. A) to 26.474 (St. D) with a mean of 39.756. Shannon-Weaver index (H´) for mammals at the upper regions (St. A and St. B) was higher than those of low regions (St. C and St. D). Berger-Parker’s index (BPI) was varied from 0.218 (St.. C) to 0.346 (St. A). Richness (R1) was different from each other and R2 was not shown significant differences (p
