Creation of locally disconnected basin boundary of attractors in population dynamics model

Nonlinear dynamic system used for simulation of fish population with application of computing tools is analyzed. Such phenomena as rout to chaos by way of period doubling cascade, intermittency, subduction, interior crisis of strange attractor are considered. New stock-recruitment models are developed which have ability to move one of two existing attractors. Basin boundaries of a hybrid-time model becomes fractal-like which is reduced to chaotic transient behavior.
