Influence of Different Factors on Abundance Estimates Obtained from Simultaneous Sonar and Echo Sounder Recordings
Haugland, Eli Kyrkjebø; Misund, Ole Arve (Journal article; Peer reviewed, 2011-12-28)Use of horizontal guided sonar in addition to vertical echo sounder may improve biomass estimation of pelagic fish schooling near the surface. But proportions of horizontal guided sonar to vertical echo integration estimates ... -
Pelagic Fish Behaviour During Trawl Sampling Off Angola
Haugland, Eli Kyrkjebø; Misund, Ole Arve (Journal article; Peer reviewed, 2011-12-16)Large sardinella (Sardinella maderensis and Sardinella aurita) in warm waters off the coast of Africa are known to be a challenge for pelagic trawl sampling, for example during acoustic surveys for abundance estimation. ... -
