Abstract:
Abstract⎯The influence of odor stimulation with solutions of the amino acids L-glutamine and L-phenylalanine
on the response of the cave fish Astyanax fasciatus (blind form) to the taste of agar pellets with L-glutamine
and L-phenylalanine has been studied. It has been established that the odors used cause a food
search behavior in fish, but do not affect the orosensory testing of the pellets. It is noted that the taste characteristics
of both amino acids differ in the evaluation of the extraoral and oral taste systems, which indicates
food selectivity in the blind cave fish, the food of which in its habitats is extremely monotonous. The
attitude to the taste of amino acids is stable with a different smell background and a changing combination
of odor and taste stimuli.
