Konsekvensutredning- verktøy for mer bærekraftig akvakultur
(Research report; Forskningsrapport, 2011-11-23)Konsekvensutredninger (KU) er et vanlig instrument i planlegging av større tiltak på land. Når det gjelder tiltak i sjøområdene er det mindre utbredt, selv om det siden 1997 har vært mulig for forvaltningen å kreve KU for «større akvakulturanlegg». Definisjonen av større oppdrettsanlegg er knyttet til en lokalitetsstørrelse på 3600 MTB, eller mer. Utviklingen innen akvakulturnæringen har medført ... -
Understanding the Size Selectivity of Redfish (Sebastes spp.) in North Atlantic Trawl Codends
(Journal article; Tidsskriftartikkel; Peer reviewed, 2012)The majority of trawl selectivity studies for the three redfish species of particular commercial importance in North Atlantic fisheries: Sebastes marinus, Sebastes mentella and Sebastes fasciatus, are based on data collected from diamond mesh codends with mesh sizes ranging from 88 mm to 147 mm. We demonstrate how results from these studies can be understood by morphological characteristics of ... -
Structure-activity relationships of the antimicrobial peptide arasin 1 - and mode of action studies of the N terminal, proline-rich region
(Journal article; Tidsskriftartikkel; Peer reviewed, 2012)Arasin 1 is a 37 amino acid long proline-rich antimicrobial peptide isolated from the spider crab, Hyas araneus. In this work the active region of arasin 1 was identified through structure-activity studies using different peptide fragments derived from the arasin 1 sequence. The pharmacophore was found to be located in the proline/arginine-rich NH2 terminus of the peptide and the fragment arasin ... -
Anti-infectious and anti-inflammatory effects of peptide fragments sequentially derived from the antimicrobial peptide centrocin 1 isolated from the green sea urchin, Strongylocentrotus droebachiensis
(Journal article; Tidsskriftartikkel; Peer reviewed, 2012)Bacterial resistance against antibiotic treatment has become a major threat to public health. Antimicrobial peptides (AMPs) have emerged as promising alternative agents for treatment of infectious diseases. This study characterizes novel synthetic peptides sequentially derived from the AMP centrocin 1, isolated from the green sea urchin, for their applicability as anti-infective agents.The microbicidal ... -
Total Catch of a Red-Listed Marine Species Is an Order of Magnitude Higher than Official Data
(Journal article; Tidsskriftartikkel; Peer reviewed, 2012)Accurate information on total catch and effort is essential for successful fisheries management. Officially reported landings, however, may be underestimates of total catch in many fisheries. We investigated the fishery for the nationally red-listed European lobster (Homarus gammarus) in south-eastern Norway. Probability-based strip transect surveys were used to count buoys in the study area in ... -
Fra nasking til næring - samarbeid om lokal utvikling
(Journal article; Tidsskriftartikkel, 2012)Naturreservatet i St. Abbs og Eyemouth er en ressurs for lokal næringsutvikling i Skottland. Grunnlaget er et lokalt samarbeid mellom fiskere, dykkere, verneinteresser og myndigheter. Kan vi i Nord-Norge lære noe av disse erfaringene? -
Institutional quality and catch performance of fishing nations
(Journal article; Tidsskriftartikkel; Peer reviewed, 2012)The relationship between annual growth in the catches of fishing nations and the quality of the institutions of those nations is analyzed. Catch volumes are used as a proxy for development, since economic performance indicators based on a common set of definitions do not exist. 49 major fishing nations were selected for this study, including 22 OECD countries and several developing countries. Three ... -
A review of bioeconomic modelling of habitat-fisheries interactions.
(Journal article; Tidsskriftartikkel; Peer reviewed, 2012)This paper reviews the bioeconomic literature on habitat-fisheries connections. Many such connections have been explored in the bioeconomic literature; however, missing from the literature is an analysis merging the potential influences of habitat on both fish stocks and fisheries into one general, overarching theoretical model. We attempt to clarify the nature of linkages between the function of ... -
Effects of similar intakes of marine n-3 fatty acids from enriched food products and fish oil on cardiovascular risk markers in healthy human subjects
(Journal article; Tidsskriftartikkel; Peer reviewed, 2012)There is convincing evidence that consumption of fish and fish oil rich in long-chain (LC) n-3 PUFA (n-3 LCPUFA), EPA (20 : 5n-3) and DHA (22 : 6n-3) reduce the risk of CHD. The aim of the present study was to investigate whether n-3 LCPUFA-enriched food products provide similar beneficial effects as fish oil with regard to incorporation into plasma lipids and effects on cardiovascular risk markers. ... -
Sequential bargaining, external effects of agreement, and public intervention
(Journal article; Tidsskriftartikkel; Peer reviewed, 2012)In some bargaining situations, agreement has implications for agents beyond the parties involved, and if so, delays in reaching an agreement or failing to reach an agreement, when this would be profitable, may imply significant welfare losses. The question raised in this paper is whether the intervention of a government, who has a positive valuation of agreement and therefore offers a subsidy, will ... -

Erfaringer og analyser fra drift av oppdrettsanlegg på eksponerte lokaliteter
(Research report; Forskningsrapport, 2012-03-29)Dette forprosjektet har hatt som mål å legge til rette for videreutvikling av forskningsrelaterte problemstillinger innen tema drift av eksponerte oppdrettslokaliteter. Eksponerte lokaliteter er her derfor å forstå som "oppdrettslokaliteter som er mer utsatt for bølger, strøm og/eller vind enn de fleste lokaliteter er i dag". Fokuset har vært på teknologi, mennesker og fisk. Prosjektet har samlet ... -
Heavy Metals in Salt Marsh Sediments of Porteresia Bed along the Karnafully River Coast, Chittagong
(Journal article; Tidsskriftartikkel; Peer reviewed, 2012-09-30)Heavy metal (Cu, Zn, Cd, Pb and Fe) concentrations in salt marsh sediments of the Karnafully River coast were investigated in this study. Sediment samples of four different sites were analysed for selected heavy metals by AAS (atomic absorption spectrophotometry). The mean values of heavy metals were 45.79 µg/g for Cu, 105.0 µg/g for Zn, 0.43 µg/g for Cd, 26.70 µg/g for Pb and 3297.38 µg/g for Fe ... -
Adjuvants and immunostimulants in fish vaccines: Current knowledge and future perspectives.
(Journal article; Tidsskriftartikkel; Peer reviewed, 2013)Vaccination is the most adequate method to control infectious diseases that threaten the aquaculture industry worldwide. Unfortunately, vaccines are usually not able to confer protection on their own; especially those vaccines based on recombinant antigens or inactivated pathogens. Therefore, the use of adjuvants or immunostimulants is often necessary to increase the vaccine efficacy. Traditional ... -
Making ecosystem-based management operational: Integrated monitoring in Norway
(Journal article; Tidsskriftartikkel; Peer reviewed, 2013)Ecosystem-based management presupposes that the state and development trends of an ecosystem - or of ecological quality - can be measured and followed. Currently, in many coastal countries there exists a variety of monitoring practices that are concerned with single issues only, and are not an integrated part of a larger framework. With the trend towards more comprehensive forms of ecosystem-based ... -

Change in Fish Community Structure in the Barents Sea
(Journal article; Tidsskriftartikkel; Peer reviewed, 2013)Change in oceanographic conditions causes structural alterations in marine fish communities, but this effect may go undetected as most monitoring programs until recently mainly have focused on oceanography and commercial species rather than on whole ecosystems. In this paper, the objective is to describe the spatial and temporal changes in the Barents Sea fish community in the period 1992–2004 while ... -
