Morphometric variations of rasbora lateristriata bleeker population in different habitat: based on truss character analysis

Abstract

Rasbora lateristriata is an alternative source of protein for the people around the river and fish consumption in Indonesia. Rasbora lateristriata also an economically fish in the streams so that people make it a prime target of the catch. Rasbora lateristriata, Bleeker called yellow Rasbora is a genus of freshwater fish from the family of Cyprinidae and is often found living in groups based on small rivers with a temperature range between 22-24 ° C, pH 6.0 -6.5. The purpose of this study was to determine the method Truss morphometric variation in the upstream, branch, middle and downstream and analyze the effects of water quality to morphometric character of Rasbora lateristriata population as scientific information in the conservation of fish. Morphometric variation of R. lateristriata based on Truss morphometric characters found their closeness between the four populations character of R lateristriata with the degree of similarity that upstream populations with 100% similarity, branch with 60% similarity, middle and downstream with 75%. Morphometric similarity value of R. lateristriata in the Sungi river area of ??77.5%.
