Estimation and classification of temporal trends to support integrated ecosystem assessment
(Peer reviewed; Journal article, 2020)We propose a trend estimation and classification (TREC) approach to estimating dominant common trends among multivariate time series observations. Our methods are based on two statistical procedures that includes trend ... -
Estimation of acoustic indices with CVs for cod and haddock in the Barents Sea winter survey 1994 – 2017 applying the Sea2Data StoX software.
(Fisken og Havet;5-2018, Research report, 2018)Sea2Data programmet StoX er brukt til å estimere akustiske indekser med CV for nordøstarktisk torsk og hyse fra vintertoktet i Barentshavet i 1994 til 2017. Indeksene er sammenlignet med indekser tidligere estimert med ... -
Estimation of acoustic indices with CVs for Northeast Arctic saithe in the Norwegian coastal survey 2003-2017 applying the Sea2Data StoX software.
(Fisken og Havet;1-2018, Research report, 2018)Sea2Data programmet StoX er brukt til å estimere akustiske indekser med CV og lengde og vekt ved alder for nordøstarktisk sei fra det norske kysttoktet Varanger – Stad i 2013 til 2017. Indeksene er sammenlignet med indekser ... -
Estimering av utkast i norsk kystfiske med garn - 2012-2018
(Fisken og havet;2021 - 1, Research report, 2021)Informasjonen om ikke-omsettelig fangst (utkast) fra Kystreferanseflåten (KRF) blir i denne rapporten benyttet til å oppskalere utkastet til å gjelde hele flåtesegmentet ved bruk av ulike innsats-faktorer. Rapporten ... -
Estimert dødelighet for utvandrende postsmolt av laks 2012-2020 - Rapport til Mattilsynet OK-program 56827 – Lakselusovervåking
(Rapport fra havforskningen;2021 - 5, Research report, 2021)For å estimere dødeligheten grunnet lakselus sluppet fra oppdrettsanlegg til utvandrende postsmolt av laks fra de lakseførende elvene med gytende biomasse > 10 kg i de 13 ulike produksjonsområdene, er det benyttet en ... -
Estimert dødelighet for utvandrende postsmolt av laks 2012-2021 — Rapport til Mattilsynet OK-program 56827 – Lakselusovervåking
(Rapport fra havforskningen;2021 - 53, Research report, 2021)For å estimere dødeligheten grunnet lakselus sluppet fra oppdrettsanlegg til utvandrende postsmolt av laks fra de lakseførende elvene med gytende biomasse > 10 kg i de 13 ulike produksjonsområdene, er det benyttet en ... -
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
