utilization of geometric morphometric techniques in assessing allometry in the present study showed that size only accounted for a 4.4% of the shape and that it did not appear allometric relationships neither for males nor for females for the selected most discriminative landmarks. These results may be useful for comparing allometric patterns of pikeperch between geographical populations or ecological variants, fitness, fish movements, spatial scales, and for studying the body size dependence of energy storage and size-related biokinetics.
