Threshold of sensation of natural amino acids in fish



On the example of the naive juvenile of the Russian sturgeon, thresholds of sensation (detection) of amino acids and their derivatives in fish are determined. There is a relationship between the thresholds of sensation of amino acids and their physico-chemical properties. Of the nine test amino acids, the minimum thresholds of sensation in fish are established for histidine, methionine, and tyrosine.
