Towards an explanation of the North Sea cod crisis. The perspective of knowledge
(Master thesis; Mastergradsoppgave, 2003-05-22)
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.) ...

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 ...

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 ...
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 ...
