Abstract

This paper provides data on the correlation analysis of morphological characteristics of the hillstream loaches Annamia normani Hora, 1931 using first-order linear regression with correlation coefficient R. The analysis examinedthe relationship between body part measurements relative to standard length and head part measurements relative to head length. The results showed positive correlations between body parts and standard length, as well as between head parts and head length. Specifically, the position of the dorsal, ventral, and anal fins, body width, head length, head width and head height, snout length, and interorbital distance were identified as important characteristics in the morphological analysis of Annamia normani.
