abstract:Sustainable fishery development indicator system (SFDIS) is a good reference that reflects fishery variations at different times and locations. It keeps the industry abreast of the latest developments and allows for timely revision of management policies and structures that could lead to its sustainable development. This study uses the Gungliau area in Taiwan as an example to evaluate the development of the SFDIS. This is the first time Factor Analysis is applied practically on the indicator aggregation. Results show that this indicator system reflects the time variation of each indicator and indicates sustainable trend at each developmental stage.
