  • The following shows the catch and escape ratios for the above simulation repeated 500 times.

    Here, the net angles of the entrance were set to 60° or 90°, and simulations were performed for each.

    The result showed that the rate of entering the playground and escaping was higher with a net angle of 90°.

    As a result, the amount of fish entering the bag net was larger with the net angle of 60°.

    We believe that set nets can be designed to selectively catch target fishes (such as mackerel, horse mackerel, and tuna) by using a model to reproduce the actual difference in their behaviors.
