A note on measuring the effects of exchange rate changes on Norwegian exports of seafood
(Working paper; Arbeidsnotat, 2002-09)The purpose of this note is to develop a very simple, yet consistent structural model of the Norwegian seafood trade that highlights how trade flows and prices are affected by changes in exchange rates. By using a class of models called Equilibrium Displacement Models (EDM’s) the model is solved for the reduced-form elasticities to indicate the effects exchange rates changes has on producer ... -
A bioeconomic model for Uganda's Lake Victoria Nile Perch fishery
(Master thesis; Mastergradsoppgave, 2002-12-12)After an evaluation of this Nile perch fishery for the period 1986 – 2000, when it constituted more than 60% of the catch, it is evident that a severe over fishing problem exits and that the fishery has never been managed for economic efficiency. All economic rent from this fishery has been and continues to be dissipated. The effort in 2000 is 64% higher than that required to take MEY and 44% ... -
Induction of tetraploid gynogenesis in the European sea bass, Dicentrarchus labrax L.
(Journal article; Tidsskriftartikkel; Peer reviewed, 2003)A preliminary study on tetraploid gynogenetic induction in the European sea bass was performed by pressure-blocking the second polar body release and the first cleavage in eggs fertilized with ultraviolet-irradiated sperm. Fertilization of eggs with genetically inactivated sperm produced only haploid development that terminated around hatching. Pressure treatments (8.500 psi for 2 min) applied at 6 ... -
Distributional effects of marine protected areas. A study of the North-East Atlantic cod fishery
(Working paper; Arbeidsnotat, 2003-01)This paper studies the distributional effects of the implementation of a marine protected area (MPA) for the North-East Atlantic cod stock. A bioeconomic cohort model with two agents targeting different age groups is used to examine how the establishment of an MPA may affect the payoffs to the two main vessel types used to exploit cod, namely, trawlers and coastal vessels. Cooperative and ... -
Fiskeren som forsvant? En studie av avfolking, overbefolking og endringsprosesser i norsk fiskerinæring
(Doctoral thesis; Doktorgradsavhandling, 2003-02-28)Hva er en fisker? Dette er det sentrale spørsmålet i denne avhandlinga. Spørsmålet er utgangspunkt for å utforske endringsprosesser i fiskerinæringa, både i fortida og i samtida. På bakgrunn av dette drøfter avhandlinga hvilke oppfatninger, forståelser og beskrivelser som til enhver tid benyttes til å definere hva fiskere er i ulike sammenhenger. Undersøkelsen starter i det som kan kalles ... -

Integrated Coastal Zone Management (ICZM). The allocation of space in Norwegian aquaculture - from local lottery to central planning?
(Master thesis; Mastergradsoppgave, 2003-05-22)Resource management in the coastal zone involves a large number of stakeholders and resource users, from traditional fishermen and recreational housing owners to state and municipal government. The aim of this study is to show how spatial scarcity in Norwegian aquaculture is not solely a technical definition, but scarcity also depends upon the social context in which it operates. That is, what ... -
Vaccination of Atlantic cod (Gadus morhua L.) against atypical furunculosis using different adjuvants
(Master thesis; Mastergradsoppgave, 2003-05-22)In recent years increased attention has been focussed on fish vaccines and vaccination against diseases in farmed fish. In this study, efficacy and side effects of vaccination against atypical furunculosis in Atlantic cod (Gadus morhua L.) were studied in an experimental trial by using different adjuvants. The different adjuvanted vaccines were administered by intraperitoneal injection (i.p.) ... -
Bioeconomic analysis of artisanal marine fisheries of Tanzania (Mainland)
(Master thesis; Mastergradsoppgave, 2003-05-28)Artisanal marine fisheries of Tanzania involve the majority of the coastal population whose survival is entirely dependent on the coastal fishery resources. In this paper the artisanal sector of the marine fisheries for the period 1987 -2000 is analysed by applying Gordon-Schaefer Surplus Production Model on time series of total catch and standardised effort. Static reference points such as open ... -
Consumption of salmon. A survey of supermarkets in China
(Master thesis; Mastergradsoppgave, 2003-05-28)To keep up with the recent trends in consumer demand for salmon product in supermarkets, an understanding of the relationship between consumption and variation of lifestyle is needed. The present paper seeks to address this question by hypothesizing that consumption is strongly influenced by consumers’ sociodemograhic status, experience of salmon, beliefs with salmon’s attributes and preference ... -
Industrial restructuring and enterprise development. The state, importance and development strategies for the fisheries sector of Vietnam
(Master thesis; Mastergradsoppgave, 2003-06-02)This paper presents the importance, the state of affairs and the development strategies of the state-owned enterprises in the Fishery sector of Vietnam. The purpose is, firstly, to review state-owned enterprise reform literature of relevance to Vietnam. Secondly, the reform of state-owed enterprises in Vietnam particularly in the Fisheries Sector is reviewed to determine the important issues and ... -
Towards an appropriate economic management regime of tuna fisheries in Ghana
(Master thesis; Mastergradsoppgave, 2003-06-02)The Ghanaian tuna fishery is a baitboat and purse seine fishery. Three main species of tuna are caught namely, Skipjack, Bigeye and Yellowfin. A detailed and comprehensive set of catch and effort data for the tuna fisheries has been obtained for the period 1980-2001. Harvest functions have been designed and estimated. By maximising the loglikelihood function by numerical methods, parameter ... -
Management of Lake Ziway fisheries in Ethiopia
(Master thesis; Mastergradsoppgave, 2003-06-02)This study has been conducted in the northern most Rift Valley lake fishery – lake Ziway. Catch & effort and economic data have been used to analyze its fishery. The aim of the analysis was to review the present management situation of the lake and to apply bioeconomic theory to estimate the maximum and economic yields of the lake. The Schaefer’s surplus production model has been employed to ... -
An assessment of the vulnerability of Ghana's coastal artisanal fishery to climate change
(Master thesis; Mastergradsoppgave, 2003-06-05)Considering the fact that nearly 25% of the Ghanaian people live in the coastal zone and about 10% depend on the coastal fishery for livelihood, it is likely that any changes in the production of the fishery may impact on the socio-economic lives of the people. For the past four decades, climatic conditions ha ve been found to be changing in the country. This period coincided with the conspicuous ... -
Behaviour and patterns of habitat utilisation by deep-sea fish. Analysis of observations recorded by the submersible Nautilus in "98" in the Bay of Biscay, NE Atlantic
(Master thesis; Mastergradsoppgave, 2003-06-05)Analysis of video recordings performed by the submersible “Nautile” in the Bay of Biscay, NE Atlantic indicated that demersal fish species are associated to different types of deep-sea habitats. Four different dive transects were analysed with respect to environmental characteristics. A total of 19 fish groups were ordinated by means of canonical correspondence analysis, and the investigation ... -
Age determination in the snapper Lutjanus guttatus (Pisces, Lutjanidae) and investigation of fishery management strategies in the Pacific Coast of Guatemala
(Master thesis; Mastergradsoppgave, 2003-06-05)The rose-spotted snapper, Lutjanus guttatus, seems to be sequentially exploited by the shrimp trawler and the artisanal fleet along the Pacific Coast of Guatemala. The growth parameters of the snapper were estimated in the present study with basis on material collected in two fishing harbours. Other biological and fishery information was compiled to simulate stock dynamics with a yield-per-recruit ... -
Conservation of wildlife. A bio-economic model of a wildlife reserve under the pressure of habitat destruction and harvesting outside the reserve
(Working paper; Arbeidsnotat, 2003-09)Biodiversity is today threatened by many factors of which destruction and reduction of habitats are considered most important for terrestrial species. One way to counteract these threats is to establish reserves with restrictions on land-use and exploitation. However, very few reserves can be considered islands, wildlife species roam over large expanses, often via some density dependent dispersal ...
