in the nutrient load on marine environments, their
distribution and channelling through the food web
and the effect on the increase of new production,
are fundamental and constitute a prerequisite for
the planning of actions for water protection measures.
The Gulf of Riga is no exception. The Gulf

Registreringer av lakselus på laks, sjøørret og sjørøye i 2004
(Research report; Forskningsrapport, 2005-06)
Results from 2004 showed that the lice infection pressure varied between the different monitoring stations in time and space and that the overall pattern was moderate to high infection in all areas. This is in spite of the fact that the fish farmers have improved their implementation of delousing strategies in fish farms. The density of fish farms is high all along the coast.

management practice. The study seeks to find out how the ...
Contingent payments in selection contests
(Working paper; Arbeidsnotat, 2005-04)
The early literature on research contests stressed the advantages of a fixed
prize in inspiring R&D effort. More recently the focus has moved towards endogenizing
the rewards to research activity in these tournament settings, since this can induce extra
effort or enhance the surplus of the buyer. We focus on a research contest as a means of
selecting a partner for an R&D enterprise, in an ...

Fishery resources of the Gulf of Tonkin, Vietnam. The state of indicator species monitored by bottom trawl surveys
(Master thesis; Mastergradsoppgave, 2005-05-20)
In the period 2001-2004 four bottom trawl surveys were carried out in the Gulf of Tonkin to
investigate the aquatic stocks in the Vietnamese sector (67,370km2). The Gulf has tropical
characteristics and great diversity of commercial species, but lately fishing pressure seems to
have grown excessively. The swept-area cruises followed a stratified random design, with a
fixed station grid imposed ...
Analysis of marine aquaculture developments in Namibia. Environmental, economic and legislative considerations
(Master thesis; Mastergradsoppgave, 2005-05-30)
