The development of computational models for fish reproduction to scenario research

The article considers new computational model of population dynamics, which is designed for application in the specialized software tools and supports event-driven simulation. The basis of the model is the original formalization of changes in mortality rate of annual generations, which depends on its density and growth rate. Proposed implementation of iterative mode by numerical solution of differential equations on the time interval is due to practical needs of the fishery. For example, this would allow assessing the effectiveness of artificial replenishment of commercial stocks at cultivation juveniles of different age or weight. Representation of the model most corresponds to the problem of formation of scenarios and analysis of various variants of continuation for situations in the fishery. Algorithmic structure allows you to dynamically change the specified set of control actions and detect signs of threatening the regime of fishing withdrawal.
