Abstract
Experiments on acoustic tagging on cod took place in a limited
area of the Barents Sea in February 1975. The work was
done during a survey with R.V. "G.O. Sars" when looking for
the distribution, abundance and size composition of cod in the
southern Barents Sea.
Nine fishes with tags having different signal-characteristics
were dropped at the same time and place. After an hour the
dropping area was left for several days. Having returned to this
point after four days, the sonar, SIMRAD SK 120, was used as
hydrophon in "receiving mode" when searching for the tagged
fishes. During approximately 30 hrs four fishes were found.
Every tag with its spesific characteristics were determined each
time.
