Abstract: The regression coefficient for Macrognathus aral juveniles and males were found to be lower than ‘3’ indicating negative allometric pattern of growth where as in females it was greater than ‘3’ suggesting positive allometric growth. Total body weight shows positive increase with total length in both male and female fishes. Different morphometric features like head length, snout length, dorsal fin length, pre dorsal length shows positive correlation with total length. Condition factor values in both male and female specimens gradually decreased before spawning season and start to increase again after the spawning season is over. Hepatosomatic index in female specimens attains peak value before spawning season and then shows a gradual decrease with the onset of spawning period.
