Computer simulation of fish behavior in relation to fishing gear. II. Computer simulation of fish behavior in relation to a trap model.

A computer simulation was carried out in order to confirm the propriety of a mathematical model of fish behavior proposed by the authors. The model parameters had been estimated on the basis of the data of the water tank experiment performed previously. The present simulation test was done corresponding to another water tank experiment whose trap configuration was dif-ferent from the previous one. We considered the following three types of trap model; the trap net without leader net, the trap net with a leader net and a single mouth, and the trap net with two mouths. The rates of entering, escaping and remaining of a 5 fish group were compared with a satisfactory result between the water tank experiment and the corresponding computer simulation.
