Kasumyan, S. Sidorov] Comparative study of behavior of testing artificial food objects (agar-agar pellets containing L-proline 0.1 M, L-alanine 0.1 M, L-glutamine 0.1 M, or L-glutamic acid 0.01 M and control pellets) by intact and olfactorily deprived (16 months) two-year-olds of the carp Cyprinus carpio (TL 8.5 cm) was performed. It was found that chronic anosmia causes in fish an increase in the latent time of response to food objects (period from pellet falling in water up to the moment of its being grasped by fish); however, the main characteristics of behavior related to sensory testing (intraoral gustatory reception) of suitability of food objects for consumption do not change in fish. Intact and deprived carps retain the pellet in the oral cavity at the first grasp for a maximum time and reduce this time with each subsequent retention, whereas the duration of intervals between the grasps do not obey this regularity. In experiments that terminate with pellet consumption, fish perform considerably less repeated acts of testing and retain the pellet at each grasping several times longer than in experiments terminating with the rejection by fish from its consumption. It is suggested that the sensory properties of the food object are evaluated by fish at the moment of its first grasping and that the results of such assessment are the basis for the subsequent behavior whose development can proceed according to two different stereotypes.
