THE STATE OF WORLD FISHERIES AND AQUACULTURE 2018 produced from fish by-products, which previously were often wasted. It is estimated that by-products account for about 25 to 35 percent of the total volume of fishmeal and fish oil produced. Fishmeal and fish oil are still considered the most nutritious and most digestible ingredients for farmed fish feeds, but their inclusion rates in compound feeds for aquaculture have shown a clear downward trend as they are used more selectively. Preparation of The State of World Fisheries and Aquaculture relies heavily on FAO’s fisher y and aquaculture statistics. FAO is the only source of global fisheries and aquaculture statistics. These statistics are structured within different data collections (capture and aquaculture production, stocks status, fish commodities production and trade, fishers and fish farmers, fishing vessels, and apparent fish consumption) and are made available to external users through different formats and tools. 4 FAO has established a series of mechanisms to ensure that the best available information is submitted by countries according to international standards. The data are then carefully and consistently collated, revised and validated, either directly (e.g. through food balance sheets) or indirectly (e.g. using consumption sur veys). In the absence of national reporting – a concern noted in several sections of Part 1 of this publication – FAO may make estimates based on the best data available from other sources or through standard methodologies, or may simply repeat previous values, which diminishes the accuracy of the statistics. Complete, accurate and timely national statistics are critical for monitoring the fisheries and aquaculture sectors, for supporting policy development and implementation at the national, regional and international levels, and for measuring progress towards meeting the Sustainable Development Goals. The importance of countr y reporting of fisheries and aquaculture data to FAO, in accordance with the obligations of FAO membership, is highlighted, and FAO continues to enhance countries’ capacit y to collect these data. n Fish and fish products are some of the most traded food items in the world today. In 2016, about 35 percent of global fish production entered international trade in various forms for human consumption or non-edible purposes. The 60 million tonnes (live weight equivalent) of total fish and fish products exported in 2016 represent a 245 percent increase over 1976. During the same period, world trade in fish and fish products also g rew sig nificantly in value terms, w ith exports rising from USD 8 billion in 1976 to USD 143 billion in 2016. In the past 40 years the rate of g rowth of exports from developing countries has been sig nificantly faster than that of exports from developed countries. Reg ional trade ag reements have contributed to this g rowth through the increased reg ionalization of fish trade since the 1990s, w ith reg ional trade f lows increasing faster than external trade f lows. In 2016, trade increased by 7 percent over the year before, and in 2017 economic g rowth streng thened demand and lifted prices, again increasing the value of global fish exports by about 7 percent to peak at an estimated USD 152 billion. China is the main fish producer and since 2002 has also been the largest exporter of fish and fish products, although the rapid growth of the 1990s and 2000s has subsequently slowed. After China, the major exporters in 2016 were Norway, Viet Nam and Thailand. The European Union (EU) represented the largest single market for fish and fish products, followed by the United States of America and Japan; in 2016 these three markets together accounted for approximately 64 percent of the total value of world imports of fish and fish products. Over the course of 2016 and 2017, fish imports grew in all three markets as a result of strengthened economic fundamentals. CAPTURE FISHERIES PRODUCTION Global total capture fisheries production, as derived from the FAO capture database, was 90.9 million tonnes in 2016, a decrease in comparison to the two previous years (see Table 1 in “Over view”, above).
