Abstract

The noise emission of the vessel, especially in shallow waters, causes a fright reaction of the fishes near the vessel. To reduce the uncertainty of hydroacoustic measurements connected with that fact, a side shifted towed body is used for the hydroacoustic stock estimation in the Baltic sea. If the towed body was running close to the surface it was quite sensitive to waves. To make the running properties of the side shifted towed body more robust a control of the center of buoyancy depending on the diving depth was introduced. The goal was set to control the towed body without additional energy supply. First results are shown.
