“…The rheoreaction of fish from natural water bodies in a hydrodynamic setup reflects these two types of behavior (Pavlov et al, 2013(Pavlov et al, , 2019Zvezdin, 2016). To distinguish between migratory and residental behavior in experiments, we propose a formal criterion that allows us to determine the type of fish behavior in the experiment.…”

The results of an experimental study of the influence of the flow velocity on the rheoreaction indices of Danio rerio, rheopreferendum and the ratio of the frequencies of various types of rheoreaction, are presented. At a crucial for fish flow velocity of 0.30, their rheopreferendum is positive, while at 0.80, negative. The ratio of rheoreaction types at these velocity levels was typical for resident fish. At a crucial flow velocity of 0.45, the rheopreferendum was not expressed, and the fish behavior was typical for upstream-migrating individuals. A decrease in the accessibility of the limnozone (limitation of the zone’s entrance width) in the circular tank reduces the number of fish returning to it and changes the ratio of their rheoreaction types. At the maximum width of the entrance (19 cm), the ratio of zebrafish rheoreaction types reflects the behavior characteristic of migrating individuals, while for all other variants (10, 3, and 1 cm) it is typical for resident forms. It is shown that the rheopreferendum is a less complete and reliable assessment of rheoreaction than the ratio of rheoreaction types. The applicability of rheoreaction indicators is considered.

“…Changes in rheoreaction resulting from various environmental factors have different reasons. It is known that the motivational component of rheoreaction during the migration of juveniles from spawning waters to feeding grounds can change rapidly (minutes, hours) and cardinally in action of illumination (Pavlov et al, 2007(Pavlov et al, , 2019 and the chemical composition of water (Zvezdin, 2016). In these cases, individuals are constantly in a migratory state and a change in rheoreaction is determined by a change in their actual behavior.…”

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.

“…Migrations of juvenile A. alburnus against the water current can be related to either foraging (Prchalová et al 2004) or the search for winter refuges (Prignon et al 1998;Lucas and Baras 2000;Prchalová et al 2004Prchalová et al , 2006, such as observed from September to November in the delta of the River Volga (Tryapitsyna 1965;Podolyako et al 2017). Alburnus alburnus migrations upstream, dominated by 1 + and 2 + juveniles, occur in a broadly-dispersed pattern (between 10-15 m) along the left and right margins of the river sections, beginning around 06:00, peaking between 12:00-15:00 and continuing until 20:00-21:00 (Pavlov et al 2019).…”

The bleak Alburnus alburnus is a medium body-size leuciscid fish that is naturally distributed across central European and western Asian fresh waters. However, during the last two decades A. alburnus has been widely introduced elsewhere in Europe and in northern Africa, mostly as a forage species for game fishes. Given its relatively recent history of invasion in non-native Eurasian waters, where it can become highly abundant, A. alburnus poses a serious risk to native communities where introduced. This study provides a review and meta-analysis of the biological traits of A. alburnus coupled with insights into its invasiveness. In its native range, A. alburnus has a moderate lifespan, inhabiting lakes or still waters in medium-to-large rivers, where it feeds mainly on zooplankton. However, non-native A. alburnus populations display high phenotypic plasticity in their biological attributes. Thus, growth, reproductive and/or dietary traits have adapted to local environmental conditions, with the species also invading lotic (stream) ecosystems. Feeding changes to benthic invertebrates, plant material and detritus when zooplankton is scarce. Such plasticity, including broad physiological tolerance, is likely to facilitate the species' adaptation and invasion of new habitats in the near future.
