Climate change and its effect on marine environment, especially ocean warming, acidification and sea level rise, impacts fisheries in different ways. However, fisheries and climate change are regulated by different international management mechanisms, which makes the current fisheries management system face challenges. Realizing this, the present paper is designed to consider whether international law should be introduced to apply better management of fisheries so as to cope with the issues arising from climate change. In addition, the paper highlights the importance of incorporating relevant principles into future fisheries regulations by examining an existing bilateral fishery agreements.
