“…And under night-time illumination, when downstream migration occurs in the river, the swimming ability of migrants became lower than that of residents (Pavlov et al, 2007). In roach underyearlings, it was shown that the critical flow rate decreases in fish motivated toward downstream migration (Kostin et al, 2016). Therefore, we believe that a decrease in the experimental indicators of the swimming ability of fish at the beginning of starvation may be caused by the appearance of motivation to currentwise movement, and not only by a change in their physiological capabilities.…”

Changes in the motivational component of rheoreaction (the ratio of rheoreaction types) during starvation in some fish species has been analyzed. The presence of fish motivation to migrate (before starvation) is the major pattern of the future changes in the motivational component of rheoreaction resulting from starvation. All fish of the families Cyprinidae and Salmonidae studied with initially behavior as resident individuals show the same type of response to starvation. Their preference for currentwise movement increases on the 2nd–5th days of starvation, then the preference for movement against the current increases on the 7th–12th days, and the ratio of rheoreaction types approaches the initial one. Juveniles of the Black Sea salmon (Salmo trutta labrax) with a motivation to downstream migration, represent a different response to starvation: the downstream movement of individuals monotonically increased from two days after starvation.
