Improving scallop (Pecten maximus and Placopecten magellanicus) spat production by initial larvae size and hydrodynamic cues used in nursery system
(Journal article; Peer reviewed, 2019)There are several factors affecting scallops during the metamorphosis process that could explain the relatively low post-larvae yield observed in hatcheries. Competent bivalve larvae respond to different settlement cues ... -
Improving size selection in the Norwegian red king crab (Paralithodes camtschaticus) fishery through modification to pot design and soak time.
(Peer reviewed; Journal article, 2023)Red king crab (Paralithodes camtschaticus) represent a valuable inshore fisheries resource for communities in northern Norway. The fishery is regulated east of the 26th meridian by vessel quotas and a minimum landing size ... -
Improving the link between science and management: Drawing upon local fishers' experience
(ICES CM Documents;1994/T:20, Working paper, 1994)Norwegian fish stock assessment has not included estimation of coastal and fjord resources until recently. The geographical area varies both in environmental and biological features. Stock assessment is especially difficult ... -

In a squeeze: Epibiosis may affect the distribution of kelp forests
(Journal article; Peer reviewed, 2019)The processes limiting the population recovery of the kelp Saccharina latissima after recent large‐scale loss from the south coast of Norway are poorly understood. Previous investigations do, however, suggest that the ... -
In sea trout, the physiological response to salmon louse is stronger in female than in males
(Peer reviewed; Journal article, 2023)The aims of this study were to compare male and female sea trout (Salmo trutta) with respect to their hypo-osmoregulatory ability over a simulated migration to seawater and their clinical and physiological response to ... -
In situ calibration of observatory broadband echosounders
(Peer reviewed; Journal article, 2020)Today, numerous scientific echosounders are used as continuously monitoring systems in ocean observatories. These echosounders are usually calibrated in shallow water, either in laboratory tanks or at random ocean docks ... -
In situ determination of bottom trawl ground gear contact
(ICES CM documents, Working paper, 2001)Exact definition of towed distance with proper ground gear contact is an essential parameter in bottom trawl swept area estimates of fish abundance. Errors in this key parameter may lead to a first order bias in abundance ... -
In situ fish target strengths derived with a split-beam echo sounder
(ICES CM documents, Working paper, 1985)In-situ target strengths of six fishes were determined with a split-beam echo sounder during cruises about Lofoten in March 1984 and the Shetland Islands in July 1984. The species and lengths, mean and standard deviation, ... -
In situ observations of swimbladder compression in herring
(ICES CM documents, Working paper, 1984)The hydrostatic function of the swimbladder in herring is experimentally investigated through in situ diver-assisted measurements of swimbladder volume on net-caught and caged fish. In agreement with morpho-physiological ... -
In situ of Cape horse mackerel (Trachurus capensis)
(ICES CM Documents;1999/J:4, Working paper, 1999)The acoustical target strength (TS) of Cape horse mackerel (Trachurus capensis) was measured in situ at 38 kHz using a submersible split beam transducer in combination with a SIMRAD EK 500 echosounder. The transducer ... -
In situ recordings of large gelatinous spheres from NE Atlantic, and the first genetic confirmation of egg mass of Illex coindetii (Vérany, 1839) (Cephalopoda, Mollusca)
(Peer reviewed; Journal article, 2021)In total, 90 gelatinous spheres, averaging one meter in diameter, have been recorded from ~ 1985 to 2019 from the NE Atlantic Ocean, including the Mediterranean Sea, using citizen science. More than 50% had a dark streak ... -
In situ sea lice egg sterilization with UVC light
(Rapport fra havforskningen;2019 - 29, Research report, 2019)Sea-cage salmon farming creates ideal conditions for population growth of the salmon louse Lepeophtheirus salmonis, potentially leading to poor welfare and mortality in farmed salmon and nearby wild salmonids. Frequent ... -
In situ swimming speed and swimming behaviour of fish feeding on the krill Meganyctiphanes norvegica
(Journal article; Peer reviewed, 2005)In situ swimming speed and swimming behaviour of dielly migrating planktivorous fish were studied at a 120-m-deep location. Acoustic target tracking was performed using a hull-mounted transducer and submersible ... -
In situ target strength observations on haddock
(ICES CM Documents;1986/B:39, Working paper, 1986)In situ target strength measurements of ideally resolved haddock have been made using the ES-400 split-beam echo sounder. The measurements are compared with the mean target strength obtained simultaneously by counting ... -
In vitro assessment of protein digestibility and mineral solubility of black soldier fly larvae meals for monogastric animals
(Peer reviewed; Journal article, 2022)Animal farming is a fast-growing sector which demands a large supply of feed materials and the search for novel feed ingredients with a smaller impact on the global environment has been intensified. However, before the ... -
