Comparison of the olfactory morphology and morphometry of three pelagic perciform species from Pakistan

1206-1214The morphology and morphometry of olfactory systems of three fishes; Scomberoides commersonnianus, Rastrelliger kanagurta and Sphyraena obtusata were explored. The olfactory organs are round in S. commersonnianus and oval in the other two species. In the present study, 19 olfactory morphometric characters and 6 ratios (of some of the traits) are quantified. In the selected species, the mean values of all the traits and ratios were significantly different among the species (p p S. obtusata and the other two species. The traits that chiefly discriminate the olfactory systems of targeted species are length of both nostrils; length, width and volume of olfactory organ
