Abstract

Rawadanau Conservation Area has main function to take care of biodiversity. The
research of fish diversity and Invasive Alien Species has been conducted. The
research was conducted in August-September 2015. The aim is to show the value
of community structures such as index of fish diversities, the similarities,
dominances and alien species. We found nine species contain 198 fish, the details
are 63 fish at Muara station, 73 fish at Jamungkal and 62 at Cibungur. The
category of Biodiversity index showed low category, as follows 1.7306, 1.1146
and 1.2153. The category of similarity index showed low-middle category between
0.259786 – 0.417703. The details are 0.417703 at Muara Station (middle
category and labil community); 0.259786 at Jamungkal Station and 0.294471 at
Cibungur Station (Low Category and depressed community), dominancy index is
in low category between 0.268-0.353, it is 0.268 at Muara Station, 0.353 at
Jamungkal Station and 0.320 at Cibungur Station. The endemic fish are spotted

fish. Alien species are plecos, pomfret, carp and catfish. The water temperature
26-27 oC, pH between 5.76-6.16,water depth 150 s/d >200 m, brightness 53.3-
66.6 m, current speed 0.12-0.15 (m/s), DO 6-6.3 mg/l and bog sediment.
