| 内容記述 | The author discussed about the shifting speed of fish school as the velocity against the ground, seperated from the 'pure' swimming velocity in a current. When fish were swimming in a current, they were seemed to hold a position constantly. But, because blind fish had not this tendency, the author recognized that it relied upon the sense of sight. On the other hand, he estimated the maximum swimming velocity of fish upon the hypothetic that "this is equal to the velocity just under the water surface when fish is going to skip up or to dive away hastily into deep"; and he got the results that the value of the maximum velocity was 200 m/min or more at least for a moment. Generally, the swimming velocity under serene condition was about 1/5 of max. velocity. Further-more, the author exprimented to investigate about the relations between shifting displacement of fish schools and their appearance on the fishing ground. And, according to the results of this experiments (discharging 100 of carp into 120 m ditch), he pointed out the possibility to estimate the source area and observation points (actual examples are spawning ground and fishing ones respectively). He could explain the shifting phenomena of tunny fishing ground through these ideas. Lastly, he concluded that it was very important to investigate about the movement of fish school because the shifting displacement was one of the most important factors which influenced to the variations of the fish stock and catch. |
