Chemosensory mediation of food searching in the Buenos Aires tetra Hyphessobrycon anisitsi (Characidae)
2016
Marusov, E. A. | Kasumyan, A. O.
Food searching behavior of the Buenos Aires tetra Hyphessobrycon anisitsi has been investigated before and after experimentally induced anosmia combined with visual deprivation. The threshold concentration of a water extract of familiar food (chironomid larvae) for fish with intact olfaction was 10–⁶ g/L. Induced anosmia led to complete loss of the search reaction to food odor. The chemosensory behavioral response to the water extract of food used at high concentrations (10⁻¹-10⁻² g/L) was not restored in fish after 1.5, 5, or 13.5 months of anosmia. The obtained results show that the external sense of taste is absent or extremely poorly developed in the Buenos Aires tetra.
