THE INVERTEBRATE FAUNA AND BIOTIC INDEX VALUE OF WATER QUALITY OF THE GREAT BERG RIVER, WESTERN CAPE

Abstract

The invertebrate fauna was sampled at seven localities in the main stream of the Berg River in 1974. These results are discussed and compared with those of Harrison and Elsworth (1958). The results obtained were also used in applying the Empirical Biotic Index of Chutter (1972) to evaluate the water quality.
