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 ...
Do stocking densities affect the gut microbiota of gibel carp (Carassius auratus gibelio) cultured in ponds?
(Journal article; Tidsskriftartikkel; Peer reviewed, 2011)
The aim of the present study was to evaluate the intestinal microbial communities of gibel carp (Carassius auratus gibelio) cultivated in two beach ponds at different stocking densities. The two ponds were both ~3.33 hm2 in acreage and ~1.5 m in depth. The stocking densities included one intensive with 2 fish m–3 while the other treated as semi-intensive with 1 fish m–3. The gut microbiota (both ...
MPA in Labor: Securing the Pearl Cays of Nicaragua
(Journal article; Tidsskriftartikkel; Peer reviewed, 2011)
Implementation of Marine Protected Areas (MPAs) has always a step-zero, i.e., an initial phase when the idea is incepted, communicated and negotiated among stakeholders. What happens during this phase is likely to have an impact later on. If not done right, the management of the MPA may encounter problems at later stage that will be difficult to correct. Inspired by this working theory, this article ...
Evaluation of probiotic strain Bacillus subtilis C-3102 as a feed supplement for koi carp (Cyprinus carpio)
(Journal article; Tidsskriftartikkel; Peer reviewed, 2011)
In this study, the effects of dietary probiotic Bacillus subtilis C-3102 (Calsporin®) on the growth performance, predominant intestinal microbiota, expression of cytokines genes in three organs (liver, intestine and kidney) and
protection against Aeromonas hydrophila infection of koi carp were investigated. Fish were fed two different diets, 1-control diet (non-supplemented) and 2-experimental diet ...
The evolution of the “harvest machinery” : why capture capacity has continued to expand in Norwegian fisheries
(Journal article; Tidsskriftartikkel; Peer reviewed, 2005)
Controlling the expansion of capture capacity has been a major challenge for the fisheries management systems around the North Atlantic. Despite focused attempts to reduce this capacity in recent years in different jurisdictions, it has continued to expand. This chapter uses a case study of changes in Norwegian fisheries to help explain why this has happened. The article supports the replacement of ...
Histological and bacteriological changes in intestine of beluga (Huso huso) following ex vivo exposure to bacterial strains
(Journal article; Tidsskriftartikkel; Peer reviewed, 2011)
In the present study the intestinal sac method (ex vivo) was used to evaluate the interactions between lactic acid bacteria and staphylococci in the gastrointestinal (GI) tract of beluga (Huso huso). The distal intestine (DI) of beluga was exposed ex vivo to Staphylococcus aureus, Leuconostoc mesenteroides and Lactobacillus plantarum. Histological changes following bacterial exposure were assessed ...
A bioeconomic MPA study based on cellular automata population growth and distribution
(Journal article; Tidsskriftartikkel; Peer reviewed, 2011)
This paper investigates possible biological and economic effects of using marine sanctuaries as a management tool, employing cellular automata techniques to model biological growth and area distribution, assuming open access to the fish stock resources outside the protected area. The cellular automata model incorporates a fish harvest model based on standard assumptions. In agreement with previous ...
Latour, natur,og havforskere : hvordan produsere natur?
(Journal article; Tidsskriftartikkel; Peer reviewed, 2004)
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 ...
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 ...
