Estimert luserelatert dødelighet hos postsmolt som vandrer ut fra norske lakseelver 2012-2017
(Rapport fra havforskningen;28-2018, Research report, 2018)På bestilling fra Mattilsynet har Havforskningsinstituttet estimert dødeligheten til utvandrende postsmolt av laks fra de over 400 lakseelvene i Norge i tidsrommet 2012-2017. Som bakgrunn for den estimerte dødeligheten ... -
Ethics of assisted evolution in marine conservation
(Peer reviewed; Journal article, 2019)Climate change is outpacing existing rates of evolution and adaptation for many marine organisms. Human societies are pushing hard to find new solutions to save and protect marine ecosystems, generating research on ... -
Evaluating acoustic-trawl survey strategies using an end-to-end ecosystem model
(Peer reviewed; Journal article, 2020)Fisheries independent surveys support science and fisheries assessments but are costly. Evaluating the efficacy of a survey before initiating it could save costs. We used the NORWECOM.E2E model to simulate Northeast Atlantic ... -
Evaluating assumptions behind design-based estimators for unreported catches
(Peer reviewed; Journal article, 2023)Understanding a fishery’s impact on the marine ecosystem requires a quantification of total catches, which include unreported catches. For recent years in Norwegian waters, unreported catches have been estimated using data ... -
Evaluating effort regulation in mixed fisheries: a Monte Carlo approach
(Journal article; Peer reviewed, 2019)This paper evaluates whether effort regulation could achieve the goal of protecting low-abundance species in mixed fisheries. We construct a two-species bio-economic model and compare the stock abundance ratio in the end ... -
Evaluation of a national operational salmon lice monitoring system - from physics to fish
(Journal article; Peer reviewed, 2018)The Norwegian government has decided that the aquaculture industry shall grow, provided that the growth is environmentally sustainable. Sustainability is scored based on the mortality of wild salmonids caused by the parasitic ... -
Evaluation of Antarctic krill biomass and distribution off the South Orkney Islands 2011-2015
(;WG-EMM-15/54, Research report, 2015-06-22)Annual acoustic trawl surveys for krill monitoring have been carried out by the Institute of Marine research, Norway near the South Orkney Islands since 2011. The survey has been conducted early in the fishing season ... -
Evaluation of black soldier fly larvae meal as a functional feed ingredient in Atlantic salmon (Salmo salar) under farm-like conditions
(Peer reviewed; Journal article, 2023)Atlantic salmon (Salmo salar) were fed diets containing black soldier fly larvae (BSFL) meal at two inclusion levels for 13 months in open sea-cages. BSFL meal replaced plant-based ingredients and dietary insect meal ... -
Evaluation of echosounder data preparation strategies for modern machine learning models
(Peer reviewed; Journal article, 2022)Fish stock assessment and management requires accurate estimates of fish abundance, which are typically derived from echosounder observations using acoustic target classification (ATC). Skilled operators are regularly ... -
Evaluation of Fisheries Sonar for Whale Detection in Relation to Seismic Survey Operations
(Peer reviewed; Journal article, 2008) -
Evaluation of potential reference genes in real-time RT-PCR studies of Atlantic salmon
(Journal article; Peer reviewed, 2005)Background Salmonid fishes are among the most widely studied model fish species but reports on systematic evaluation of reference genes in qRT-PCR studies is lacking. Results The stability of six potential reference ... -
Evaluation of sampling strategies for age determination of cod (Gadus morhua) sampled at the North Sea International Bottom Trawl Survey
(Peer reviewed; Journal article, 2020)The North Sea cod stock assessment is based on indices of abundance-at-age from fishery-independent bottom trawl surveys. The age structure of the catch is estimated by sampling fish for otoliths collection in a length-stratified ... -
Evaluation of the maximum limits for selenium in Atlantic salmon feeds

Evaluering av tiltak for å fremme bærekraftig sameksistens mellom fiskeri og havbruksnæring (ProCoEx)
(Nofima rapportserie, Research report, 2016)Fiskeri- og havbruksnæringen har felles interesser i kystnære farvann, næringene må i størst mulig grad se nytten i å samarbeide om bruken av områdene uten urimelig forringelse av felles næringsgrunnlag. Økt tilstedeværelse ... -
Evaluering av tiltak for vern av kysttorsk i sør innført juni 2019
(Rapport fra havforskningen;2022 - 48, Research report, 2022)Vi ser i våre data ingen tegn til at bestandssituasjonen for torsk er endret i indre Skagerrak, ytre- og indre Oslofjord siden tiltak ble innført i 2019. Havforskningsinstituttets data viser stabilt lave fangster av torsk ... -
Evaluering av ulike agn til snøkrabbefiske i Barentshavet
(Peer reviewed; Journal article, 2021)Akkar og sild er de vanligste agnene som blir brukt under snøkrabbefiske i Barentshavet i dag. Ut fra økonomiske og etiske betraktninger er det viktig å erstatte dagens agn med alternative restråstoffkilder som har liten ... -
Evidence for light-controlled migration amplitude of a sound scattering layer in the Norwegian Sea
(Journal article; Peer reviewed, 2016-06-09)The oceanic sound scattering layer (SL) is an ubiquitous acoustic signature of mesopelagic fishes and invertebrates that are important food sources for the oceanic macrofauna and players in the biological carbon pump. We ... -
