Day and night fish distribution pattern in the net mouth area of the Norwegian bottom-sampling trawl
(Journal article; Peer reviewed, 1990)A high-frequency scanning sonar, mounted as a net sonde, was used to study fish behaviour in the mouth area of the Norwegian bottom-sampling trawl. Fish distribution patterns were significantly different by day and night. ... -
Echo abundance indices of 0-group fish in the Barents Sea, 1965-1972
(Journal article; Peer reviewed, 1977)In order to obtain estimates of year class strength of 0-group fish, joint international surveys have been conducted each year since 1965 in the Barents Sea. The density of fish has been estimated by visual grading of the ... -
