Abstract

Morphological variation study of Bada fish (Rasbora maninjau, Lumbantobing) from Maninjau Lake has been conducted. There are two types of R. maninjau, the study was aimed to determine the morphological variation between them. The data was analyzed with the Mann Whitney U test. The result showed that there is a morphological variation between R. maninjau type-1 and type-2. The characters are Head behind eye length (HBEL), Eye diameter (ED), Depth of caudal peduncle (DCP), Length of caudal peduncle (LCP), Predorsal distance (PDD), Preanal distance (PAD), Dorsal fin length (DoFL), Anal fin length (AFL), Pelvic fin length (PeFL), Pectoral fin length (PFL), Caudal fin upper length (CFUL) and Caudal fin lower length (CFLL).
