Orosensory Food Testing in Fish: Chronology of Behavior.

Abstract

The orosensory food testing behavior in fish was studied using the nine-spined stickleback Pungitiuspungitius as an example. The patterns of the chronology of manipulations performed by fish in testing food objects were identified. The existence of two stereotypical patterns of feeding behavior was confirmed, and their new characteristics were obtained. The relationship between the responsiveness to food and the predisposition of fish to feeding was revealed.
