Ecosystem-based marine fishery management is a new direction for fishery management
that prioritizes the management of the entire ecosystem rather than the
target species individually.
• Most ecological economic models for EBFM follow the population approach,
which ignores the interaction between the biological and physical components of
marine ecosystems. It may be necessary to apply the process-functional approach
for ecological economic models. Nutrients may be chosen as the currency for ecological
economic models because nutrient flow connects biological and physical
components of marine ecosystems.
• The move from single-species marine fishery management to EBFM may require
several stages, and it is important to include the physical component of the ecosystem
in fishery management plans in addition to the target stock and its predatorsand prey. The less traceable environment effects on fisheries such as climate
change should be also investigated and included in the management plans.
