Tråling over steindekte rørledninger i Nordsjøen
(Fisken og havet, Research report, 1997)Between 17 June and 1 July 1997 an experiment was conducted to determine to what extent gravel dumped on pipelines crossing the sea floor obstructs bottom trawling in the North Sea. The investigation was carried out by ... -
trec: An R package for trend estimation and classification to support integrated ecosystem assessment of the marine ecosystem and environmental factors
(Peer reviewed; Journal article, 2023)Solvang and Planque [ICES Journal of Marine Science, 77, pp.2529–2540, (2020)] provided a trend estimation and classification (TREC) approach to estimating dominant common trends among multivariate time series observations. ... -
Tredje samlerapport: Velferd for triploid laks i Nord-Norge - Sluttrapport, utsett 2019
(Rapport fra havforskningen;2021 - 44, Research report, 2021)Denne rapporten tar for seg velferden til 14 grupper av triploid laks satt ut i Nord-Norge vår, sommer og høst 2019. To av gruppene satt ut om våren hadde perfekt utgangspunkt med god smoltkvalitet og feilfri transport. ... -
Trekk fra dypvannsrekens biologi i norske kystfarvann - I. Vigrafjorden, Møre
(Fiskeridirektoratets skrifter, Serie Havundersøkelser, Research report, 1945)The life history of the deep sea prawn (Pandalus borealis) in the Vigrafjord on the west coast of Norway is traced on the basis of 8 samples totaling 4010 specimens collected continuously from September 26. 1943 to May ... -
Trends in growth and reproductive parameters of Barents Sea harp seals
(Working paper, 1993)Data from reproductive organs of Barents Sea harp seals Phoca groenlandica with corresponding age determinations have been analysed in combined samples collected during three periods: 1963-1972, 1976-1985 and 1990-1993. A ... -
Trends in marine survival of Atlantic salmon populations in eastern Canada
(Peer reviewed; Journal article, 2021)Declines in wild Atlantic salmon (Salmo salar) abundance throughout the north Atlantic are primarily attributed to decreases in survival at sea. However, comparing trends in marine survival among populations is challenging ... -
Trenger laks fettsyren EPA for optimal immunrespons? Rapport FHF prosjekt EPA-laks
(Research report, 2021)Innhold av de langkjedede omega-3 fettsyrene i dietter blir ofte oppgitt som sum EPA + DHA, uten å ta spesielt hensyn til ratioen mellom de to fettsyrene. Laksens behov for DHA er velstudert. EPA omgjøres i stor grad til ... -

Trial of a New, Split-beam Echo Sounder
(ICES CM Documents;1984/B:21, Working paper, 1984)The first at-sea trial of a new, split-beam echo sounder, the SIMRAD ES380 system, is described following a review of the split-beam principle, outline of its realization in hardware and software, and description of ... -
Triploid (sterile) farmed Atlantic salmon males attempt to spawn with wild females
(Journal article; Peer reviewed, 2014-06-18)Genetic interaction between farmed escapees and wild conspecifics represents one of the major environmental challenges faced by the Atlantic salmon aquaculture industry. In order to mitigate genetic interactions, triploid ... -
Triploid Atlantic salmon and triploid Atlantic salmon × brown trout hybrids have better freshwater and early seawater growth than diploid counterparts
(Peer reviewed; Journal article, 2021)The use of reproductively sterile triploid salmonids would enhance the environmental sustainability of the aquaculture industry by preventing genetic exchange between escapees and wild conspecifics. To this end, we assessed ... -
Triploid Atlantic salmon Salmo salar have a higher dietary phosphorus requirement for bone mineralization during early development
(Peer reviewed; Journal article, 2020)The effect of a dietary phosphorus regime in freshwater on vertebra bone mineralization was assessed in diploid and triploid Atlantic salmon, Salmo salar. Fish were fed either a low phosphorus (LP) diet containing 10.5 ... -
Triploid Atlantic salmon × brown trout hybrids have similar seawater growth and welfare issues as triploid Atlantic salmon, but both were heavier at harvest than their diploid counterparts
(Peer reviewed; Journal article, 2022)Interspecific hybridisation may improve the farm performance of sterile triploid salmonids via heterosis (i.e. hybrid vigour). We assessed growth over the final 293 days in seawater, and harvest quality, in diploid and ... -
Triploidy effects growth, life history strategies, and bone health in Arctic char (Salvelinus alpinus), but does not impact cataract incidence
(Peer reviewed; Journal article, 2021)Skeletal deformities and ocular cataracts have limited the farm performance of sterile triploid salmonids, but have not been assessed in Arctic char (Salvelinus alpinus). We repeatedly radiographed mixed-sex diploid and ... -
Triploidy leads to a mismatch of smoltification biomarkers in the gill and differences in the optimal salinity for post-smolt growth in Atlantic salmon
(Peer reviewed; Journal article, 2021)Sterile triploid Atlantic salmon (Salmo salar) show inconsistent seawater grow-out, but the reason why remains unclear. The purpose of this study was to determine the salinity optima of triploid post-smolts. Diploids and ... -
Trivial gain of downscaling in future projections of higher trophic levels in the Nordic and Barents Seas
(Peer reviewed; Journal article, 2023)Downscaling physical forcing from global climate models is both time consuming and labor demanding and can delay or limit the physical forcing available for regional marine ecosystem modelers. Earlier studies have shown ... -
