ABSTRACTWith the global economic and social development, environment and climate issues has attracted the world's attention. Reducing greenhouse gas emissions and protecting the natural environment has become the consensus of the world. The Copenhagen climate conference held in 2009 proposed new requirements on national emission reduction targets, so the development of low-carbon economy is the only way to achieve sustainable social development. On the background of the land resource dwindling, marine economy development has become one of the main driving force to promote global economic development. As one of the traditional marine industries, marine fisheries can not be ignored. Therefore, achieving marine fisheries low-carbon development is of great significance for achieving the sustainable development of marine resources. On the other hand, the marine fisheries a low-carbon development is a very complex process and has significant external impact, so the marine fisheries of low-carbon need international cooperation. As a big marine fishery country, China should develop low-carbon fishery. Now many marine provinces such as Shandong began to explore ways of low-carbon marine fishery. Yet, on the whole, Chinese marine fisheries is also facing many problems, of which one of the most important things is that the lack of high-technology support and regional cooperation. So this thesis puts forward to the low-carbon development path for mariculture, marine fishing, aquatic products processing. On the macro-level, China should establish new policies and measures to prompt low-carbon marine fisheries so that it can increase international cooperation, and facilitate the realization of China's marine low-carbon fisheries by the introduction of technology, capital and advanced management experience. On the other hand, for marine fishery low-carbon development has remarkable externality, no nation can internalize it. Therefore the development of marine fishery low-carbon needs for international co-operation. For international cooperation has remarkably technological spillover effect and economy of scale effect, international cooperation can be made in marine aquaculture, ocean fishing and aquatic products processing industry widely and deeply. International cooperation mode can take the government as the leader, ocean fishery organizations as active coordinators and the fishery enterprises as the main body. Finally, the realization of marine fishery low-carbon development and international cooperation need effective policy support, the government work on the following aspects: first of all, the ocean low-carbon development and the realization of international cooperation is a long process, the government must consider and realize the potential difficulties and obstacles fully to formulate long-term development planning; secondly, it must give more policy supports to marine enterprise on taxes and financial authority, encouraging the low-carbon reform and international cooperation; thirdly, government should participate in international affairs actively, and formulate bilateral or multilateral fishery dispute resolution mechanism with the surrounding and other fishery countries in case of emergencies, making cooperation smooth.
