Abstract
Hatchery rearing underyearlings of the Black Sea salmon Salmo trutta labrax at the age of five-six months (nine-ten months before the beginning of smoltification) divide into two spatial groups—bottom group and pelagic group. This is caused by lack of territory (bottom area): the minority of fish are bottom-dwelling—such fish are territorial, they extrude the majority of individuals to the water column. It is determined experimentally that the bottom-dwelling fish belonging to the bottom group, in comparison with the fish of pelagic group, are characterized by higher critical flow velocities and lower locomotor activity in the rheogradient. Part of individuals with the static type of rheoreaction among them is higher. The fish from the pelagic group do not have such resource as individual territory. This fact modifies the probability of manifestation of resident and migrant behavior after starvation (during ten days). The individuals from the pelagic group demonstrate the behavior characteristic of future migrants (downstream movement) to a higher degree. The individuals from the bottom group, in comparison with pelagic fish, demonstrate, to a great degree, behavior typical for future residents (upstream movement).
