| 内容記述 | The influence of diurnal fish behavior on its biomass estimation was studied using acoustic methods, an ADCP (Acoustic Doppler Current Profiler) and a quantitative echo sounder. The survey was carried out during 11 to 15 January 1994 with the R/V Yoko-maru, and four transects were executed off the western coast of Kyushu. The acoustical data of ADCP and quantitative echo sounder were collected by a new method using four round-trip surveys along each on a transect with a length of about 30 miles during an time period of 24 hours and 50 minutes. Additionally, CTD casts were conducted at an interval of about 3 nautical miles on each transect. A coastal front was formed in the eastern part of a transect between the Goto Islands and Kyushu, and a southward current was clearly seen there. Many fish schools were clearly observed at the coastal front in the Goto-Nada. The estimated biomass was varied in a day. In the present study, the acoustic problems resulting from fish behavior were discussed quantitatively. | |||||||||||
