A Study of the Morphological Differences in Otolith for Some Fish Species of Two Families: Cyprinidae and Cichlidae

Abstract

The current research paper aims at identifying and clarifying the main morphological differences in Otolith for some fish species belonging to two families, Cyprinidae and Cichlidae. These two families exist in the local Iraqi waters. This paper tries to identify each species and diagnose them microscopically to arrive at these differences among these Otolith.
