The Asia-Pacific region is remarkably diverse and wide ranging, geographically, in its flora and fauna, culturally, institutionally and economically. The region includes the two most populous countries in the world, China and India, a greater part of the Asian continent, the Australian continent, and many small islands, mostly in the Pacific Ocean, which are some of the smallest island nations in the world. Fisheries and aquaculture are socio-economically important sectors to most nations in the Asia-Pacific region and most nations in the region have high rates of fish consumption, mostly sourced from aquaculture although the small island nations depend to a greater extent on capture fisheries. This review entails analyses of the aquaculture sector in Asia-Pacific including the status and trends, progress made in achieving sustainable development, salient challenges, issues and anticipated future development. Status and trends are based on data extracted from the FAO Fishery and Aquaculture Statistics (FAO, 2020a; FAO, 2020b), unless stated otherwise, and are mostly for the period from 2008 to 2018 and occasionally for the period from 1990 to 2018 for relevant historical comparison and longer-term contextual analyses.

FAO Fisheries and Aquaculture Circulars While many countries in the Asia-Pacific region have made commendable efforts to set up policies, as well as administrative, legal and regulatory frameworks to properly develop and manage aquaculture, some countries are still lagging behind. And in some of the countries that have made conducive policies, implementation is delayed by a lack of financial and skilled human resources. This issue must be addressed as a priority if the Asia-Pacific aquaculture sector is to continue to develop sustainably.

This review reports on aquaculture development trends and challenges during 2000–2018 in the European Region covering 51 countries including European Union member states. Aquaculture production in the European Region is composed of marine molluscs and diadromous, marine and freshwater fish. It reached 3.4 million tonnes in 2018, while having a value of USD 16.6 billion. Atlantic salmon and rainbow trout combine to give nearly two million tonnes, with molluscs providing 0.7 million tonnes; marine fish species supplied 0.4 million tonnes and freshwater fish 0.3 million tonnes. In Europe, the strongest aquaculture growth has been seen in non-European Union states (e.g. Norway, Turkey, Russian Federation) while several European Union states have diminished production (e.g. France, Netherlands, Italy). The growth in value (5.8 percent) is higher than production (0.9 percent), which is now dominated by salmonids (nearly 60 percent), primarily Atlantic salmon. Mediterranean marine fish farming is mainly for gilthead seabream and European seabass. European cyprinid production in freshwater has increased slightly, where the Russian Federation, Czechia and Poland are the biggest producers. Mussels are the principal shellfish reared, led by Spain, followed by oysters in France and clams in Italy. While publicly quoted companies have led salmon development in Northern Europe, elsewhere aquaculture is done, with few exceptions, by SMEs and micro-enterprises. Mechanisms for financial support exist for aquaculture development throughout Europe but these have notnbeen matched by anticipated results. When unpredictable and time-consuming licensing procedures are combined with extreme competition for space and strict environmental regulations, both growth and investments are discouraged. Technology development focus has been given to structures appropriate for marine off-shore or ‘open ocean’ operation. The use of recirculating aquaculture systems (RAS) for large operations has also developed, both for hatcheries and for farms. Treatment for diseases and parasites remains problematic. Use of the same vaccines, veterinary treatments and disinfectants is not standardised, restricting the best health and welfare practices. Access to appropriate and efficient ingredients for formulated feeds remains a key issue for European fish farming, directly influencing productivity and profitability. The European Union is the world’s largest single market for seafood and the most important destination for European aquaculture production. With preferences declared for wild products vs. farmed, the habits of the European consumer have been studied, indicating evolving influences on purchase decisions. These include the use of additives, food miles, climate change, acceptance of manufacturing practices, cost and access as well as health benefits.

This document summarizes the status and trends of aquaculture development in North America, focusing on Canada and the United States of America, with some discussion on Bermuda, Greenland, and Saint Pierre and Miquelon. Relevant aspects of the social and economic background of each country are followed by a description of current and evolving aquaculture practices and the needs of the industry in terms of resources, services and technologies. Impacts of aquaculture practices on the environment are discussed, followed by a consideration of the response by the industry to market demands and opportunities, and its contribution to social and economic development at regional, national and international levels. External pressures on the sector are described, including climate change and economic events, along with associated changes in governance. The review concludes with an analysis of the contributions of North American aquaculture to the Sustainable Development Goals, the FAO Strategic Objectives, and the FAO Blue Growth Initiative. Throughout the review, outstanding issues and success stories are identified, and a way forward is suggested for each main topic.

FAO Fisheries and Aquaculture Circulars Aquaculture is recognized as having the potential to boost growth and jobs in coastal and inland areas in Europe. Policies such as the Blue Growth strategy, the reformed Common Fisheries Policy (CFP) and the Baltic Sea Region Strategy highlight aquaculture as a key component in achieving economic growth. However, challenges remain, including the lack of a coherent national aquaculture policy.

FAO Fisheries and Aquaculture Circulars Whereas aquaculture in Latin America and the Caribbean is progressing at rates above world averages, growth is slowing due to governance, planning and environmental issues, among others. This report provides a comprehensive overview of the challenges facing aquaculture in the region, as well as opportunities for further development.
