The purpose of this study was to analyze the distribution pattern, size and high-length relationships of the Indo Pacific tarpon Megalops cyrinoides in the Belawan River. This is exploratory research with purposive randomly sampled method. The results showed that Morisita index value were reached of 0.299 in station 1, 0.121 (station 2), 0.277 (station 3), thus the distribution of indo pacific tarpon have a uniform spread pattern. Based on total sample of fishes divided into 3 classes: small size from (9.0 – 24.9 cm), medium from (25 – 40.9 cm) and large (> 40 cm). The dominant fish belongs to the young fish category. Similarly, caught fish was light and medium weight category (young fish). The results of the morphometric fish followed the equation: W = 0.3978 L 0,9980 , with coefficients of determination (R 2 ) = 0.8732.
