dc.description.abstract | Introduction: Observations made by echo sounder (Ona 1988) have shown that cod (Gadus morhua L.) may
avoid an approaching survey vessel horizontally and vertically. However, there has been a
lack of information on the escapement behaviour of the individual fish. This short note
discribes an experiment carried out in a shallow fjord in Northern Norway, where the
reactions of single cod towards a small survey vessel during bottom trawling were studied,
using ultrasonic tagging technique. | no_NO |
