Tapeworm (Eubothrium sp.) infestation in sea caged Atlantic salmon decreased by lice barrier snorkels during a commercial-scale study
(Peer reviewed; Journal article, 2021)Reports of infestation by marine parasitic tapeworms (Eubothrium sp.) and an associated growth reduction in Norwegian farmed salmon are on the rise. With few acceptable treatment options available, due to drug resistance ... -

Tareundersøkelser i Nordland i 2017
(Rapport fra havforskningen;9-2018, Research report, 2018)Havforskningsinstituttet har i perioden 2013-2017 gjennomført undersøkelser i forbindelse med prøvehøsting av stortare (Laminaria hyperborea) sør i Nordland. I forkant av prøvehøstingen i 2017 ble tarevegetasjonen undersøkt ... -

Tareundersøkelser i Nordland i 2019
(Rapport fra havforskningen;2020 - 9, Research report, 2020)Havforskningsinstituttet har i perioden 2013-2019 gjennomført undersøkelser i forbindelse med prøvehøsting av stortare (Laminaria hyperborea) på kyststrekningen Sømna (65° 20’ N) – Vega (65° 33’ N) i Nordland. Det ble i ... -
Target strength and tilt angle distribution of lesser sandeel (Ammodytes marinus)
(Master thesis, 2011-08-09)Lesser sandeel (Ammodytes marinus) was investigated acoustically as well as using video camera in two field experiments in 2007 and one in 2008, both during North Sea sandeel surveys by the Norwegian research vessel “Johan ... -

Target strength measurements of fish
(Journal article; Peer reviewed, 1977)During the summer of 1971, target strength measurements of fish were made at two frequencies, 38 kHz and 120 kHz. The relationships between dorsal aspect target strength and fish length were worked out for four species. ... -
Target strength measurements of fish
(Symposium on acoustic methods in fisheries research, Bergen, Norway, 19-22 June, 1973, Conference object, 1973) -
Target strength of polarized fish
(ICES CM documents, Working paper, 1987)The effect of behaviour on target strength is simulated through computation of the average target strength with respect to a range of normal orientation distributions. The mean tilt angle is varied from -30 to 30 deg for ... -
Target strength of tiny roach
(ICES CM documents, Working paper, 1987)Seven frozen specimens of surface-adapted roach (Rutilus rutilus), of lengths 32-40 mm and masses 0.20-0.49 g, have been sectioned with a precision microtome. The swimbladder contours have been digitized and the swimbladder ... -

Target strengths of Antarctic krill (Euphausia superba) at 38 and 120 kHz
(Journal article; Peer reviewed, 1990)Encaged aggregations of live krill in good to pristine condition have been ensonified at 38 and 120 kHz. Concurrent underwater television observations of behavior resemble those made by underwater divers in naturally ... -
Target strengths of Antartic krill (Euphausia superba)
(ICES CM Documents;1988/B:6, Working paper, 1988)Encaged aggregations of swimming krill have been measured at 38 and 120 kHz. The results indicate that the target strength values are substantially lower than previously assumed.
