Genus Rasbora is a freshwater fish belonging to the Cyprinidae familia distributed covering the Asian region, especially in Southeast Asia. There are 90 species of fish Rasbora scattered around the world where 56 species distributed in Indonesia and 3 species are endemic to Indonesia. Rasbora fish used as an alternative source of protein because protein is high at 33.4 g / 100 g. Rasbora higher protein content than the protein content of carp and milkfish, Rasbora also contain high fluorine and contains omega3. This study aimed to describe the longitudinal distribution and population structure in the basin Rasbora lateristriata Sungi, Tabanan. Analysis of population structure based on weight and the total length, determine the interaction between physical and chemical factors with an abundance of Rasbora lateristriata. This study used a survey method with purposive random sampling technique to collect the sample. This study uses three stations by topography and environment, namely the upstream, midstream and downstream. Rasbora species diversity and abundance will be calculated by cluster analysis, longitudinal distribution and population structure will be explained descriptively. The interaction between physical factors with an abundance of Rasbora will be analyzed by principal component analysis. In the current study found that two species Rasbora Rasbora lateristriata and Rasbora sp. with 132 individual species of Rasbora lateristriata and distributed longitudinally along the river Sungi on the middle and downstream. Lateristriata Rasbora weight ranging from 1, 3 to 6 grams, the total length ranges from 4 to 7.5 cm. Lateristriata Rasbora distribution is affected by the DO, temperature, TSS and BOD. The existence of Rasbora lateristriata influenced by light intensity and depth
