| Abstract | ||||
| Mahseer fish is a native Indonesian species whose population is declining in the wild. Cultivation and restocking efforts are important conservation strategies aimed at maintaining the sustainability of natural populations. However, low genetic variation is often observed in cultivated populations, posing a challenge when these fish are reintroduced into natural habitats. Morphometric measurements offer an efficient method for assessing the population status of both cultivated and wild Mahseer fish. This approach also provides novel baseline information for the Mahseer species Tor soro found on the island of Java. Samples of T. soro were obtained from the KF Belong fish pond in Subang, West Java, and from the Prego tributary in Central Java. Nineteen morphological traits were recorded and analyzed using Principal Component Analysis (PCA). The results revealed significant differences between the cultivated and wild populations. PCA effectively separated these populations based on traits such as standard length (SL), body depth (BD), pre-anal length (PAL), body width (BW), and pre-dorsal length (PDL), as well as pre-ventral length (PVL). These findings suggest that T. soro is capable of maintaining most of its non-functional morphological traits in cultivation environments, while functional traits such as BD tend to adapt in response to environmental conditions. Additionally, body deformities were observed in the cultivated population but not in the wild population. | ||||
