ABSTRACT: Rawadanau
Conservation Area has main function to take care of biodiversity. Theresearch
of fish diversity and Invasive Alien Species has been conducted. Theresearch
was conducted in August-September 2015. The aim is to show the valueof
community structures such as index of fish diversities, the similarities, dominances
and alien species. We found nine species contain 198 fish, the detailsare 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 between0.259786 – 0.417703. The details are 0.417703 at
Muara Station (middlecategory and labil community); 0.259786 at Jamungkal
Station and 0.294471 atCibungur Station (Low Category and depressed community),
dominancy index isin 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 gouramy, common snakehead, climbing gouramy, gondang snail and
silver barb fish. Alien species are plecos, pomfret, carp and catfish. The
water temperature26-27 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.
