The objectives of this research project were to investigate and develop methods for the assessment of optimal net benefits from the licensing of foreign vessels operating in national fisheries jurisdictions (EEZs or other extended zones). Following the development of the theoretical methodology the objective was to prepare software in the form of an analytical tool for decision making in the financial planning of surveillance and enforcement and the quantification of licence fees and penalties. The approach was limited to theoretical investigations of the ways in which the marginal value of a nationally controlled resource (the difference between income fishing inside a zone as opposed to fishing outside a zone) could be used, in conjunction with known parameters (fish prices, catches, surveillance costs etc), to estimate the optimum combination of income, surveillance costs and the legal penalties that might apply to non-compliance. The theoretical models developed are described in appendix 1 to this document. The computer model which puts the theoretical model into practice is described in Appendix 2.
