Title

MORPHOLOGY AND ANATOMY OF THE OLFACTORY ORGANS OF A HILL-STREAM FISH, SISOR RHABDOPHORUS (HAM.)

Abstract

The morphology and anatomy of a hill-stream fish, Sisor rhabdophorus (Ham.) has been studied. The paired olfactory chambers are dorso-laterally situated, each communicating by a circular anterior inlet and an oval posterior outlet. The olfactory rossette is elongated in shape and can be placed under Burne's3 rossette column Il or with Bateson's1 rosette type2. The number of lamellae in the rosette increases with the growth of the fish and new lamellae are always added at its anterior end. The total olfactory area in this fish is considerably greater than the total retinal area. This entitles it to belong to Teichmann's24 group of nose-fishes comprising of solitary, twilight and nocturnal predators. The olfactory organs of the fishes are distinctly well developed. They are of great biological, significance since they play an important role in behaviour such as procurement of food, recognition of sex, defence against the predators, paternal behaviour and orientation.1-24 Uptill now the hill stream fish S. rhabdophorus has not been studied by any author. Due to the above fact the morphology and anatomy of the olfactory organs of this fish has been studied.
