Abstract 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 fl

Abstract— The study presents the behavior and movement characteristics of climbing perch Anabas testudineus in the “dry maze” installation. Two types of behavior were identified in climbing perch when the water level in the starting tank decrea

Abstract 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 futu

The features of the growth and early maturation of brown trout Salmo trutta L. in the Alatsoya River (Republic of Karelia) are studied. As a rule, the age of brown trout in this river does not exceed 3 years and one of its life strategies is the form

The seasonal dynamics of the motivational component of rheoreaction (ratio of rheoreaction types) has been studied in roach Rutilus rutilus L. inhabiting the Rybinsk Reservoir, Russia. The circular hydrodynamic tank with limnozone is used. The change

On the example of zebrafish Danio rerio, a new hydrodynamic installation “circular tank with limnozone” was tested to determine one of the indicators of the motivational component of rheoreaction in fish: the ratio of rheoreaction types. In contr

The motivational component of rheoreaction has been determined in 4-month-old juvenile rainbow trout Oncorhynchus mykiss on different diets. It is shown that the diet increasing by 28% from the initial level reduces the motivation of fish to move dow

Unlike in nonregulated rivers, new ecological filters are formed in artificial reservoirs: structures (gradient zones between biotopes) which affect the behavior and distribution of juvenile fish and therefore change parameters of the downstream migr

Rheoreaction and concentration of thyroid hormones in blood of juvenile rainbow trout Oncorhynchus mykiss is studied during starvation (12 days). It is found that starvation predominantly stimulates downstream migration of fish and decreases the conc
