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 bioencapsulation of florfenicol in rotifers (Brachionus plicatilis)
(Journal article; Peer reviewed, 2010-11-11)The rotifer Brachionus plicatilis is one of the most important live-feed organisms used in the larval culture of marine fish. Bioencapsulation of florfenicol in rotifers was investigated by delivering it directly to the ... -
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 ... -
Evaluating the effect of seismic surveys on fish — the efficacy of different exposure metrics to explain disturbance
(Journal article; Peer reviewed, 2013-06-05)To assess potential disturbance effects on fish from seismic air-gun surveys, we described several metrics to characterize the exposures from such surveys, including the number of emissions by area and time, and metrics ... -
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 emamectin benzoate and substance EX against salmon lice in sea-ranched Atlantic salmon smolts
(Journal article; Peer reviewed, 2015-04-08)Experimental releases of Atlantic salmon smolts treated with emamectin benzoate (EB) against salmon lice have previously been used to estimate the significance of salmon lice on the survival of migrating smolts. In recent ... -
Evaluation of Fisheries Sonar for Whale Detection in Relation to Seismic Survey Operations
(Peer reviewed; Journal article, 2008) -
Evaluation of potential reference genes for real time RT-PCR studies in Atlantic halibut (Hippoglossus Hippoglossus L.); during development, in tissues of healthy and NNV-injected fish, and in anterior kidney leucocytes
(Journal article; Peer reviewed, 2010-05-11)Background Real time RT-PCR has become an important tool for analyzing gene expression in fish. Although several housekeeping genes have been evaluated in Atlantic halibut (Hippoglossus Hippoglossus L.), appropriate ... -
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 ... -
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 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 ... -
