Status, distribution, and morphometric analysis of the genus <i>Trichopodus</i> in Sumatra, Indonesia

Trichopodus, the genus of dwarf gourami fish, is oldest in Osphronemidae family, with six valid species, three which are found Sumatra. In this study, status, distribution, and morphometrics Trichopodus leerii, T. pectoralis, trichopterus from Sumatra were observed analyzed. Although these species can be distinguished based on phenotypic characteristics, it still possible to misidentify them small or preserved samples. analyses carried out specimens collection Museum Zoologicum Bogoriense, combined literature status. The results showed that pectoralis least concern category. had widest followed by pectoralis. leerii smallest distribution a near-threatened conservation Further analysis revealed 23 25 measured morphological characteristics informative, first axes principal component morphometric data explaining 51.28% total variance sample. using combination pectoral fin length, eye diameter, pelvic anterior snout width. Cluster there consistency various sample locations, where same clade. This research contributes our understanding status employs provide practical key classifying
