Developing a decision support system to manage fisheries externalities in New Zealand's Exclusive Economic Zone

Abstract

New Zealand marine fishing activities create many types of environmental externalities. Legislation requires that the externalities be internalised and fisheries management agencies must choose from a wide range of instruments which are best suited to the task. Selection of best instruments can be aided by following a hierarchical decision process, which first screens the universe of instruments to produce a likely set, then tests that list against implementation criteria to establish the feasible set. Instruments in the feasible set can be evaluated against a range of environmental, Treaty of Waitangi, economic, socio-cultural and management criteria. This approach to selection can be formalised in decision support software to provide a useful tool for fisheries management agencies.
