| 内容記述 | This research is focused on the problem of environment destruction at the seabed due to fishing by bottom trawls. The aim of this research is to reduce the damage to the seabed by fishing gear. Experiments were conducted in the East China Sea between June 16, 2007, and June 18, 2007, by Training ship Kagoshima-maru. In the experiments, a self-recording depth meter was fitted on a bottom trawl net on the head and ground ropes for clarifying the motion of the net. The experiments were conducted during a normal fishing operation and a hove - up , let - go warp(in this, the warp is first normally set ,then is hove up three times every 20 m ,and is then let go three times every 20 m). The motion of the bottom trawl net can be clarified by analyzing the data acquired by the self- recording depth meter. In future, the motion of the bottom trawl gear including otter boards need to be clarified; the experiments and analysis methods need to be improved: - and more data need to be recorded. If these goals are fulfilled, this research will provide useful data for developing a fishing method using a bottom trawl, that would cause reduce damage to the seabed. |
