Study on Behavior of Fish School Around Aggregation Devices

The behavior of the fish school around the aggregation devices is evaluated numerically and experimentally. Numerical model of the fish behavior is based on the Sannomiya's model and is applied to the behavior of the Goldfish. In the tank tests the movement of the fish near of the artificial aggregation devices was analyzed by video system. Results of numerical simulation are compared with experimental results. Finally the attraction and repulsion parameters of the devices found to be a very important in estimating the the fish behavior.
