dc.description.abstract | A high-frequency, short-range sonar is tested for trawl-geometry
measurements on pelagic and bottom trawls. The sonar was
operated on a standard, coaxial trawl sonde cable, and produced
excellent images of the trawl opening and panels. Data showing
non-ideal performance of the pelagic sampling-trawl at several
depths and speeds, together with corrected geometry are presented.
At short range, the position of fish entering the
bottom trawl could be measured. | no_NO |
