抄録

In this paper, the attention is focused on the escape behaviour of prawn from a pot for the purpose of applying these data to investigate the catching mechanism of a small shrimp pot. To assess the applicability of the numerical method developed for laboratory test to field experiment, a series of experiments was performed in the fishing ground using six model pots. The number of prawns in a pot were counted every 2h (9:00 A.M. -5:00 P.M.) for each pot when hauled. The model equation satisfactorily fitted the changes over time in the number of prawns remaining in the pot after beginning the experiment. It was found that the escape behaviour of prawn from a pot was affected by the height of the neck above the base.
