沿岸における小型刺網漁業とその資源-VIII

総括と論議

抄録

The author studied the interrelations of his conclusions (refer to his previous papers I to VII) regarding the different aspects of coastal gill-net fishery.
Based on such studies, he wishes to make the following suggestions:
1) In the coastal fishing, the farther out one goes, the greater becomes the catch.
2) The more carefully one selects the fishing gear according to the objective fish, the season and the fishing ground, the more the catch will increase.
3) In order to increase the catch and at the same time preserve the fish resources, it is better to fish for migrating rather than resident fish, and spawning or adult feeding fish than immature feeding fish.
