| 内容記述 | Understanding of the bottom contact condition of trawl fishing gear is important to examine proper gear design and trawling methods. It is also valuable to estimate swept area of a bottom trawl in the groundfish resources survey. In this study, the authors developed the Bottom-Contact Recorder, which is simple and low cost. Main body of the Bottom-Contact Recorder is the cylindrical case made of stainless steel (11cmφ×30cm) and contains an inclination sensor and a data-logger. The Bottom-Contact Recorder is suspended to the footrope of the trawl gear. When the footrope contacts the bottom, the angle of inclination of the Bottom-Contact Recorder is measured by the inclination sensor and data are recorded to the data-logger every 0.5 seconds for 270 minutes. A series of experiments to check the durability and performance of the Bottom-Contact Recorder were carried out in the tank and in an actual trawl operation. It was confirmed that the Bottom-Contact Recorder was useful in practical trawl fishing. | |||||||||||
