The olfactory organ of a fish shows considerable diversity, reflecting the degree of development and ecologicalhabitats [15]. Olfaction plays a major role in food searching, fright reaction to alarm substance, defence,migration, and reproduction [6, 7]. Catla catla is a surface feeding omnivorous fish and possesses a weakerolfactory sense in locating food, depending more on their gustatory sense or sight...

Olfactory cues play an important role in the behaviour of fish, such as the procurement of food,recognition of sex, defence against predators, parental behaviour, and orientation [13]. Olfaction isa mediator of chemical signals and is involved in diverse teleost behaviour [10]. The olfactory organof fish is the only vertebrate organ in which nerve cells are directly exposed to the aquatic ecosystem...

The topological architecture and functions of different cells of the olfactory  epithelium in Wallago attu (Bleeker) have been systematically studied using  a scanning electron microscope. The elongated olfactory rosette of the fish  consists of 62 to 64 primary lamellae in each left and right rosette...

The olfactory epithelium of Scatophagus argus (Linnaeus) was investigated by light and scanning electron microscopy. The elongated olfactory organ is made up of 20 to 22 primary lamellae arranged on both sides of the narrow median raphe. Sensory and non-sensory regions are located separately on each lamella...

The olfactory organ of Oreochromis nilotica was studied by means of light and scanning electron microscopes. The oval shaped olfactory apparatus consists of 19–20 lamellae radiating from a central raphe...
