  • 917 Development of multiagent-type indivisual-based model for ascending behavior of migratory fish

抄録

The 3D ascending behavior of migratory fish is modeled using the individual-based model and an agent-type movement decision scheme. The perceived stimuli strength of migratory fish are estimated with four physical variables: velocity, strain, pressure and light intensity. The fish movement at each time step is selected from among the prescribed five movement paterns. Qaulitative validity of the simulation results on the ascending behavior is verified through numerical examples.
