Abstract

Within discrete model process of movement of fi sh population is set by a fi nite-dimensional Markov matrix. Change of this matrix as its adaptation to a condition of fodder resources and management is formalized. Numeracally found the key characteristic of spatial adaptation is a vector of distribution of times of stay of population in those or regions of reservoir. It appeared that this vector is own vector (Perron’s vector a fi nal matrix) of movement.
