USING BMWP SCORING SYSTEM, ASPT INDICES AND AQUATIC INSECTS TO ASSESS THE WATER QUALITY OF SOME STREAMS OF BACH MA AREA IN THUA THIEN HUE PROVINCE
Abstract
Aquatic insects have been used to evaluate the water quality of Bach Ma area in Thua Thien Hue province through the BMWP scoring system for Vietnam and ASPT indices. The study was carried out between March and December of 2010. As a result, 27 families of aquatic insects belonging to 3 orders (Ephemeroptera, Plecoptera and Trichoptera) were recognised. Among these, 18 families belong to the list of the BMWP Viet scoring system. The data analysis shows that the BMWPViet scores are relatively high, the biotic indices (ASPT) range from 7.10 to 8.71. Aquatic insects have been used as biotic indices to classify the water quality as fairly clean (Oligosaprobe) or very clean. This evaluation corresponds to the water quality assessed by phisio-chemical methods.
Keywords: Aquatic insects, Ephemeroptera, Trichoptera, Plecoptera, Bach Ma National Park, ASPT biotic index, water quality.
