Model Experiments on Sea Fixed Nets for Fishing Amber-fish, Seriola

II Trap Nets set on the Fishing Grounds under Strong Tidal. Currents

Abstract

By the same method as used in the previous report, the deformation of amber-fish trap nets under various currents was examined with two models, of which the original nets are as shown in Figs. 1 and 2.
The photographs reproduced in Figs. 4 and 5 show the forms of the two nets respectively, and in each, each column, those under the currents in several directions prevailig in each fish-ing ground (Fig. 3), while from top to bottom in each column, at the current velocities of 0, 1/4, 1/2 and 1 mile/hour respectively.
