Abstract

Aims: Determine the main morphometrical traits influencing body weight in male Hampala Barb (HB) fish. Place and Duration of Study: The fish were taken from Kampar Kiri River at Mentulik Village, Kampar Regency, Riau Province. This research was conducted in February-April 2018. Methodology: The survey method used in this research takes morphometric measurements of fish. Hampala fish is used as the object of research. The survey method is a research method that is carried out directly on the object of research without giving special treatment to the object under study. A total of 26 morphometrical traits were measured from 42 male HB fishes. Results: Research showed that the average body weight of HB fishes was 245.24±136.54 g. Four morphometrical measurements of maximum body height, pre-dorsal length, pre-ventral fin length, and caudal pendulum height were selected as the leading four variables to predict body weight with the coefficient of determination (R2) of 0.95. Therefore, a variable of maximum body height can predict the body weight with an R2 value of 0.91. Conclusion: The body weight of Hampala fish can be accurately predicted with morphometric measurements. The maximum body height can influence the body weight of Hampala fish with the R2 value of 0.91. Overall morphometrical measurements of maximum body height, pre-dorsal length, pre-ventral fin length, and caudal peduncle height can describe the body weight of Hampala fish with R2 = 0.95.
