Abstract

Rasbora lateristriata has a declining population structure, especially in the upstream Sungi river. This is largely attributed to changes in environmental factors, such as the quality of the river water. The decline is also caused by the presence of fish varieties that interbreed with the natives, threatening their existence. In general, the varieties with morphological diversity have a better chance of adapting to environmental changes. The purpose of this study is to determine how the decline in Rasbora lateristriata fish can be prevented. The samples were taken at the upstream, branch, center, and downstream using purposive sampling, while data were analyzed by ANOVA using SPSS version 20. There were no significant differences in the colors of Rasbora lateristriata obtained in the upstream, midstream, branch, and downstream. The average resulting color was greyish black. Cluster Character SL, TL, and weight indicate that Rasbora lateristriata fits into three main clusters. The fist cluster is a grouping of upstream and downstream. The second one is the first cluster grouping with branches. The Cluster III is a grouping of Cluster II with the middle. The rich colors and morphometric of lateristriata Rasbora fish in the river are affected by water quality, including DO, pH, and temperature.
