Intact channel catfish conditioned to the L-amino acids, proline, arginine, alanine, and lysine, discriminated these stimuli from all other amino acids tested. Behavioral structure-activity tests indicated that L-pipecolate was the only effective agonist of the L-proline conditioned response. For channel catfish in which one of the paired olfactory organs was surgically removed, the number of turns to the conditioned stimulus was 40% fewer than those of intact catfish; however, these semiosmic channel catfish discriminated the conditioned from nonconditioned stimuli, as evidenced by their responding to the conditioned amino acid, with a two- to threefold greater number of turns than to the nonconditioned amino acids. Irrespective of the number of conditioning trials attempted, catfish with both olfactory organs removed were unable to discriminate the conditioned from the nonconditioned stimuli.
经L - 氨基酸、脯氨酸、精氨酸、丙氨酸和赖氨酸条件反射训练的完整斑点叉尾鮰，能将这些刺激与所有其他测试氨基酸区分开来。行为结构 - 活性测试表明，L - 哌啶酸是L - 脯氨酸条件反应的唯一有效激动剂。对于成对的嗅觉器官之一被手术切除的斑点叉尾鮰，对条件刺激的转向次数比完整鮰鱼少40%；然而，这些半嗅觉斑点叉尾鮰能够区分条件刺激和非条件刺激，这可通过它们对条件氨基酸的反应来证明，其转向次数比对非条件氨基酸的反应多两到三倍。无论尝试的条件训练试验次数多少，两个嗅觉器官都被切除的鮰鱼无法区分条件刺激和非条件刺激。
