Application of a Sustainable Fisheries Development Indicator System (SFDIS) for Better Management Outcomes in Taiwan Offshore and Coastal Fishery

A sustainable fisheries development indicator system (SFDIS) is proposed in this article to monitor management of Taiwan's offshore and coastal fisheries. Demonstration of its application shows that the ecological index is tending toward sustainability but to conserve fisheries’ resources it is necessary to strengthen habitat protection and management through a partnership approach. The economic index is tending toward unsustainability as a result of a decline in fisheries’ Gross Domestic Product (GDP), value, economic production, and investment. An aging fisherman population and decreasing social performance and resilience contribute to unsustainability of the social index. By contrast, the institutional index is sustainable because of improved management efficiency, ability, and capacity-building. However, some problems exist with regard to compliance and acceptability of institutional expense. Overall, the SFDIS suggests that an increase in employee number, incorrect statistical data, and unacceptable institutional expense will make Taiwan's offshore and coastal fisheries unsustainable in the long run.
