Abstract

Macrozoobenthos has an important role as detritivore in water ecosystem. Macrozoobenthos community also act as a biomonitoring instrument. The purpose of this study is to know the composition, density, diversity, evenness, and dominance of macrozoobenthos at Blanakan Fish Pond. This study was done from February to June 2018. Macrozoobenthos samples were collected from 3 stations and each station consist of 3 fish ponds. Sampling on each ponds was done by purposive random sampling on 3 sampling points with twice repetition on each point. Water abiotic factors sampling was done on each points. Macrozoobenthos samples were identified and analyzed using Shannon-Wiener diversity index, Pielou evenness index, Simpson's dominance index, Sorensen similarity index, and t-test. The results showed that there are six species of macrozoobenthos from 3 classes found, which are Melanoides tuberculata, Brotia costula, Cerithidea cingulata, Nephtys inornata, Cossura sp., and Erpobdella sp. Highest species density at Blanakan Fish Ponds is Brotia costula, amounting to 10907 ind./m3. The diversity and evenness of macrozoobenthos at Blanakan Fish Ponds classified as low and there is a dominant species at Blanakan Fish Ponds. There is no difference between macrozoobenthos diversity on 3 stations.
