| Abstract: | Olfactory sensitivity of juvenile (0 year) Atlantic cod Gadus morhua to 20 L‐amino acids was studied by recording electroencephalograms (EEG) from the olfactory bulb. Leucine, methionine, asparagine, glutamine, alanine and threonine were highly stimulatory; proline, phenylalanine, aspartic acid and tryptophan were the least stimulatory. Threshold concentrations determined for four amino acids were 10?8 M for alanine, 10?7 M for arginine and leucine and 10?6 M for glutamic acid. |
