Abstract

A clear sexual dimorphism is p e n t in Pomadays maculahts (Bloch). Females are larger and heavier than the males of the same age group. The Mack blotches on the lateral side of the body are more clearly imprinted in males than in the females. The black basal spot present on the edge of the dorsal fin is more prominent in males than in the females. The dorsal fin in female is more filamentous and protruding. The width of the anterior rim of the opercle in female is broader than that in,the male. Anterior part of the upper-Jaw is broader in females. Caudal peduncle is longer in male than that in the female. Females dominate the males in all morphological measurements.
