Societal cost of fishing activities comparison for three Southeast Asia Delta regions base on Ecost model

Coastal fisheries are important components of fisheries sector in Southeast Asia. However, conflicts are arising from excessive fishing effort due to increasing economic and social motivation. The purpose of this article is to present the application of an integrated approach to assess the societal cost and fishing policies of fishing activities in three delta regions of Southeast Asia by constructing ECOST model. Here, the Pearl River Delta, the Gulf of
Thailand and the Mekong Delta have been chosen to carry out comparative analysis from economic, ecological and social aspects. The results indicate that overfishing in three South Asia delta regions has brought out the great ecological cost which causes net benefit of whole fisheries community falls to be negative.
