Knowledge of people's understanding of environmental problems is vital for the effective implementation of the ecosystem approach to marine management. This is especially relevant when conservation goals are aimed at ecosystems in the deep-sea that are remote to the consciousness of most people. This study explores public perceptions of the deep-sea environment among the Scottish and Norwegian public. ...

Cultivation of diatoms may help alleviate the pressure on wild fish stocks for marine nutrient availability in aquaculture feed and for human consumption. However, the lipids in microalgae biomass are easily deteriorated, both trough lipolysis and degradation of polyunsaturated fatty acids (PUFA). Proper storage conditions are therefore necessary to maintain the lipid quality. Additionally, the ...

Denne rapporten tar for seg velferden til 24 grupper av triploid laks satt ut i Nord-Norge 2014-2017. Noen av de tidlige smoltproduksjonene var kjennetegnet av lav eggkvalitet, sykdom eler andre problemer i settefiskfasen, men dette forbedret seg utover i prosjektperioden. For sjøfasen viser dataene at den triploide laksen i mange av tilfellene utviklet sår i vintersesongen med påfølgende høy ...

Parasites play an important role in ecology due to their potential influence on the biodiversity and dynamics of ecosystems. The complexity of interaction between parasites and their hosts is crucial to understanding the host’s populations dynamics, behaviour as well as interconnections between food chains in an ecosystem. Parasites have wide applications as bio-indicators for example to detect and ...

Summary report from VKM’s scientific opinions for 2016 - 2017<br>The goal of this report is to highlight research needs and data gaps that are of future importance for food safety and protection of the environment and thereby improve the national knowledge base. This report is the latest in a series of reports on research needs and data gaps published periodically by the Norwegian Scientific Committee ...

In the North-East Atlantic demersal trawl fishery targeting cod and haddock, the interest on fishing gear designs that preserve fish quality and welfare has grown. However, the gear configurations tested so far imply practical challenges, therefore, more user-friendly designs are still sought by the industry. For a new design to be considered, it needs to have size selective properties that are at ...

The Greenland shark (<i>Somniosus microcephalus</i>, Squaliformes: Somniosidae) is a long-lived Arctic top predator, which in combination with the high historical and modern fishing pressures, has made it subject to increased scientific focus in recent years. Key aspects of reproduction are not well known as exemplified by sparse and contradictory information e.g. on birth size and number of pups ...

To obtain insight into perceptions of how fish welfare and health is governed in Norwegian aquaculture, this study investigates three conflict cases: salmon lice, pancreas disease and farm siting. Using surveys and in-depth interviews, it highlights challenges and solutions as perceived from different professional groups. The results show that the current inflexible limit of the number of salmon ...

The ocean is a lifeline for human existence, but current practices risk severely undermining ocean sustainability. Present and future social−ecological challenges necessitate the maintenance and development of knowledge and action by stimulating collaboration among scientists and between science, policy, and practice. Here we explore not only how such collaborations have developed in the Nordic ...

Denne miljøundersøkelsen er den tredje etter at Miljødirektoratet i 2014 påla Finnfjord as å utarbeide et program for vannovervåking, og gjennomføre dette i vannforekomsten Finnfjord Indre. Første rapport ble sendt inn 29 februar 2016, og i en tilbakemelding fra Miljødirektoratet i brev datert 4 april 2016 ble det varslet om behov for en ny undersøkelse for å kartlegge omfang og spredning av ...
