| Abstract: | - 1.1. The olfactory responses to amino acids were recorded from the bulb of the red sea bream (Chrysophyrys major) and the conger eel (Conger myriaster).
- 2.2. The threshold concentration for l-glutamine was 10−7 M in the sea bream and below 10−8 and 10−9 M in the conger eel, and it was found that amino acids are good olfactory stimuli in both species.
- 3.3. A comparison of the olfactory spectrum of amino acids of the sea bream with that of each of three species of freshwater fishes revealed a high similarity of spectra.
