Abstract Olfactory Sensitivity of the Nile Tilapia, Oreochromis Niloticus, to Amino Acids M. Fares*, T. Shoji*', R. El-S. Saleh*2, M. A. Sobeih*2, Z. H. Ahmed*2 and H.Ueda* *Toya Lake Station for Environmental Biology, Faculty of Fisheries, Hokkaido University, Abuta 049-57, Japan *'Faculty of Pharmaceutical Science, Hokkaido University, Sapporo 060, Japan *2Faculty of Veterinary Medicine, Suez Canal University, Ismailia, Egypt The olfactory sensitivity of the Nile tilapia, Oreochromis niloticus, to fourteen amino acids was investigated using electrophysiological recording techniques. The relative stimulatory efficacy (RSE) of the fourteen amino acids determined at 1X104 M revealed two distinct groups of stimulants. Serine, alanine and cysteine were the most stimulatory, while betaine and proline were the least. The remaining amino acids were intermediate. Sex of the fish did not affect RSE. The magnitudes of olfactory nerve responses increased exponentially with logaritbinic increases of stimulus concentration from the minimum threshold to 1X104 M. The calculated average minimum detection threshold is 1X10826 M which is within the range reported previously for fish species. Key words: Nile tilapia; olfactory sensitivity; amino acids; chemosensitivity. Introduction Feeding behaviour is an elective process in an animal, since specific food items are selected from a variety of nutrient sources within the environment. This selection is mediated by two separate factors: chemical constituents of the food item and the animal's own chemosensitivity. The olfactory systems of fish have been shown to be highly sensitive to chemical stimuli (Hara, 1975). The fish olfactory epithelium is similar in structure to that of the other vertebrates and, because olfaction takes place in an aquatic medium, a wide variety of compound classes are suitable stimuli. Among these compounds amino acids have been demonstrated to be feeding cues and act as potent olfactory stimulants (Carr, 1982). Considerable effort to measure the chemosensitivities of different fish species has been expended. 1
