Abstract
  • Applied research is often motivated by the economic benefits it will give rise to. These benefits are due to either improved production techniques or new products. The realisation of these objectives depends much on the assessment of different research alternatives and allocation of resources between them. Also within aquaculture research one of the main goal is to start production of new species. Successful research will effect the profitability of the production by changing such factors as the feed coefficient, the mortality, the roe proportion, the fish price uncertainly, etc. The aim of this study is to develop a general and theoretical approach that could be used in priority setting of different research project for example in aquaculture. A model of the decision of a potential fish farmer considering to start culturing a new species is build in order to determine the sensitivity of the profit to variations in both variables and the uncertainty concerned. Influence diagrams are used as a modeling method because uncertainty and its formulation are crucial, especially before a species is in production. The structure of the model is general and it can easily be used for almost any species, the payoffs of different types of research are the result of the costs and the probability of success of the research projects are evaluated independently. The information on the payoffs, costs and feasibility are then used to compare different research elements and to draw conclusions of the appropriate research policy for different species. The use of the model is illustrated with a case study of whitefish coregonus spp. On the basis of the whitefish data used, the result is that improvement in the feed coefficient would benefit the fish farmer twice as much as the equal percentage improvement in mortality or growth.
