THE DISTRIBUTION AND BIODIVERSITY OF FISHES IN LEBAK PAMPANGAN SWAMP SOUTH SUMATRA PROVINCE
Abstract: This research was
conducted to evaluate the fish distribution and biodiversity within three types
of swamp ecosystem with different water sources in Pampangan Sub-district
during July to December 2011. The field observation were conducted in three
different types of swamp. Ecological data and samples were collected from three
sampling points in each swamp type. Parameters including local distribution,
diversity index, similarity index, evenness and species richness, were
analyzed. The results show a number of 9,723 fishes corresponding to 46 species
were collected, the fish categorized into 16 families belonging to five orders.
Eight species were found in all type of swamps i.e. Mystus nemurus, Channa
striata, Cyclocheilchthys apogon, Cyclocheilichthys armatus, Pristolepis
fasciata, Puntius lineatus, Osteochillus hasselti, and Trichogaster pectoralis.
A diversity index of fishes in Pampangan Swamp ranged from 2.31 to 2.85,
indicating moderate values. The evenness index was high more than 50%. The
highest similarity was found between type 1 and type 3 of (0.43). The highest
diversity index (2.85) found in type 2 of swamp indicates the swamp in more
stable condition.
