    Abstract

    Fish morphometrics is an important aspect in fish taxonomy and fish biology studies. The aspect ratio (A) of fishes is related to metabolism and food consumption. It is also as an attribute for determining swimming speed that influences escape from predators and resulting survival in the wild. In this study the aspect ratio of 54 species of commonly exploited marine fishes using a manual graph method that can be used for comparisons across species is presented. Unlike digital imaging methods, this procedure does not involve the 'perspective' and 'distortion' errors which means that it can be used even for fishes with large caudal fins and allows results to be compared with other studies.
