Research on the habitat preferrence by Changeable hawk-eagle (Nisaetus cirrhatus) (CHE), Crested serpent-eagle (Spilornis cheela) (CSE), and White bellied sea-eagle (Haliaeetus leucogaster) (WSE) was conducted at Nature Recreation Park of Lake Buyan and Lake Tamblingan and Surrounding area between February and July, 2016. Data collection was conducted through field observation using the “look down method” and the “look up method” combined with placement of observation points. Data collection was analysed by principle component analisys (PCA) method. Research results related to preferenced habitat were as follows: (1) the CHE prefered fragmented forest, secondary forest, and cultivated forest types habitat. (2) The CSE prefered habitat types of farming land, residence, and sosial forest. (3) The WSE prefered just one habitat type, that was the wet land habitat type.

Nusa Dua is a popular tourist resort in Bali, where many hotels and other tourist facilities were built. In this resort, the sewage is centralized processed in a Sewage Treatment Ponds called “Unit Pengolahan Air Limbah PT ITDC” which is also often called Lagoon Nusa Dua. Nusa Dua sewage treatment ponds have 5 units of ponds, namely Pond 1A, 1B, 2A, 2B, and Pond 3. In ponds 2B and 3, tilapia fish (Oreochromis mossambicus Linn.) was raised as a water quality bio-indicator. The aim of this research was to determine the histology condition of the gill of tilapia fish that raised in the Nusa Dua sewage tretment ponds which were then used as an indicator of water quality in these ponds. The research employed a complete randomized design in which 16 samples were taken from two sampling sites with eight replications. Results of this research showed that histologic changes of the gill that were observed including edemas, fusions, and hyperplasias of secondary lamellas as well as telangiectases.   Keywords: Nusa Dua sewage, Oreochromis mossambicus L., gills, histology, bioindicator

Freshwater prawn (Macrobrachium rosenbergii (de Man)) farming in Bali needs to be supported by the provisionof healthy prawn larvae. Vibriosis infection can be a limiting factor on larval production system which cause highmass mortality in larvae. Therefore a bacteriological study is very important to identify of Vibrio species whichcan cause vibriosis in freshwater prawn larvae. Screening of Vibrio bacteria carried on larval rearing water atUPT Pembenihan Dinas Kelautan dan Perikanan Provinsi Bali which located in Pesinggahan Village, Klungkung.During study, 5 Vibrio isolates can be characterized (VSP01, VSP02, VSP04, VSP05 and VSP06) which wereisolated as dominant Vibrio bacteria in larval rearing water. Koch postulate test results showed that VSP06 cancause vibriosis in freshwater prawn larvae. The result of identification by BBL Cystal™ Identification Systems andidentification book Bergeys’s Manual of Determinative Bacteriology Ninth Edition (Holt et al., 1994), BL6 wasidentified as Vibrio anguillarum.

Panglipuran Village is one of the traditional villages in Bali that still prioritizes harmonization and sense of togetherness.
