Abstract
This study developed an IBM (individual-based model) to model fish
movement trajectories integrating hydraulic stimulus variables
(turbulent kinetic energy (TKE), velocity (V) and strain rate (SR)) to
which fish responded, and the rules for individual fish movement. The
fish movement trajectories of the target fish, silver carp
(Hypophthalmichthys molitrix), were applied to model fish trajectories
in a 1\% vertical slot fishway at a discharge of 13.5 L/s. Agreement
between measured and simulated trajectories implied the plausibility of
the movement rules, which illustrated that the fish movement
trajectories model has the preliminary ability to track individual fish
trajectories for this fishway.
