Case Study 3, Approach 5, Analysis of the impact of CPUE and price levels on the economic behaviour of the fishermen

Objective

The objective of approach 5 is to analyse the impact of CPUE and price levels on the economic behaviour of the fishermen. Basically this approach involves the development of the economic equations for the bio-economic OM.

Results

Regarding this objective, a project report exploring the effects of salmon price and CPUE data on the fishing effort of Finnish, Swedish and Danish fishermen has been written. In this paper non-linear regression models has been applied to analyze times series of fishing effort, salmon catches, CPUE, salmon prices and gross productivity of catch per unit of effort.

Abstract: We study the impact of CPUE (catch per unit of effort) and price on the economic behaviour of the commercial and semi-commercial salmon fisheries in the Baltic Sea. We conduct a time series analysis by using non-linear regression models in order to provide inputs to a simulation model that is used to study the biological and economic effects of different management options. We consider three fishing nations harvesting Baltic salmon: Finland, Sweden, Denmark, and three different gear types: driftnets, longlines and trapnets. The time series data covers years from 1987-2005. Our results provide evidence both the goal and profit maximisation behaviour of the salmon fisheries.

Considerable progress has also been made in relation to the bio-economic modelling of Baltic salmon. Currently two manuscripts have been written from which the other has been submitted and the other will be presented in two scientific conferences during the summer 2008. The present bio-economic OM observes 4 countries with fishing fleets including 2-5 commercial fisheries using different gears. The economic data used to calibrate the model include price and fishing costs time series by country and by fishery. The model maximises the net present value (NPV) of salmon fishery, with fishing effort as the decision variable. Recent progress regarding the bio-economic modelling has been presented in a shared COMMIT/EFIMAS deliverable.
