Beyond Social Dilemmas in Sea Mouth Management: Impacts of Sea Mouth Opening and these Responses to Lagoon Fisheries in the Hokkaido Region, Japan

Abstract

"This paper explores linking lagoon fisheries and sea mouth management in case studies of the Hokkaido region, Japan. In nature, lagoons face dangers of closing the inter-connected mouth through sediment transport. Under the circumstances, development of lagoon fisheries largely depends on maintenance of the sea mouth bridging the sea and lagoon. However, social dilemma situations in sea mouth management tend to arise due to involvement of different interests and needs among relevant stakeholders. In this paper, case studies were conducted to explore highlighting the impacts of sea mouth opening while addressing the heterogeneity characters in sea mouth management. The findings will provide a challenge to encourage the identification of over coming the dilemma situation over sea mouth toward sustainable lagoon fisheries."
