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 INTRERSET 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. USING HILSENHOFF FORMULA FOR BIOTIC INDEX (BI):, BI= SNIAI/N WHERE NI 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. TABLE (1) GIVES AN EVALUATION OF THE WATER QUALITY BASED ON THE BIOTIC INDEX THUS CALCULATED.
