Commission for the Conservation of Antarctic Marine Living R esources acts as the executive body for Antarctic fisheries management with Convention on the Conservation of Antarctic Marine Living R esources( CAMLR Convention) as the legal framework. As the only multilateral agreement for the comprehensive management of Antarctic marine living resources,CAMLR Convention has received a wide international recognition. This paper analyzes the highlights of CAMLR Convention in Antarctic fisheries management,namely,open access to membership,sophisticated institutional structure,capability of keeping pace with the times,diplomatic wisdom,measures against IU U,advanced fisheries management philosophies,etc. Meanwhile,Antarctic fisheries management also encounters challenges,which should be addressed in the process of exploration. China is an important fishing state at Antarctic O cean.Investigation for Antarctic fisheries resources and research into its exploitation are of significant importance for China,which calls for the establishment of China's Antarctic fisheries policy. 展开更多

Nigeria is the most populous black nation in the world, with an estimated population about 150 million people. Its citizens as at the end of 2012 have a projected fish demand of 2.66 million tonnes of fish. Fish supply within the said period was 1.32 million tonnes. This figure was made up of 0.7 million tonnes from importation and 0.62 million tonnes from both artisanal and aquaculture. Of the local production aquaculture contributes only 200 000 tonnes. Studies have shown that fish catch from the wild has reached its maximum production limit and production from this area is currently on the decline. Nigeria has about 1.75 hm2 of suitable sites for aquaculture development. Aquaculture production for 2012 was a meager 200 000 tonues. Aquaculture though a veritable means is faced with a lot of constraints ranging from government's wrong focus on industrial fisheries instead of aquaculture, poor policy formulation and non-implementation fisheries development programmes among others. In spite of these constraints, there were also the following aquaculture investment opportunities such as production of fishing equipment, establishment of modern fish farms, shrimp fishing, fingerling production, table size fish production, brood stock production, fish feed production, ornamental fish farming, production system design and construction, capacity building in project management, packaging and branding. 展开更多
