| Popis: | 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 three 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 has 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 Rasbora lateristriata in the Sungi River, 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 is using survey method with purposive random sampling. 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 analysed by principal component analysis. In the current study found Rasbora lateristriata with 85 individual species and distributed longitudinally along the river Sungi on the upstream is 14individuals, middle stream is 34 individuals and downstream 47individuals. Lateristriata Rasbora weight ranging from one point three to six grams, the total length ranges from four to seven point five cm. Rasbora lateristriata distribution is affected by the DO, temperature, TSS and BOD. The existence of Rasbora lateristriata influenced by light intensity and depth. |
