    Review of the state of world marine fishery resources 2005
    Also available in:

    This document updates the regular reviews of the state of the world's marine fisheries and fishery resources, based mainly on official catch statistics throughout 2002 and relevant stock assessment and other complementary information available until 2004. The introductory chapters refer to the global situation and major trends of world marine capture fish production and the state of the world marine fishery resources. More detailed information is provided for each FAO statistical area, together with a discussion of the major trends and changes that have occurred with the main fishery resources exploited in each area and comments on the stock assessment work undertaken in support of fisheries management in each region. Special sections address the global issue of tunas and tuna-like species and other high profile topics such as those dealing with world squid resources, deep-sea fisheries and long-term climate change and fisheries. Summary tables are provided for each statistical area s howing historical and recent catches for the major marine resources and judgements on their current state of exploitation.

    Large pelagic fish are important to the small-scale, commercial and recreational fisheries in many Caribbean Community (CARICOM) countries. They are seen as an area with potential for growth. As most are transboundary, their management requires collaboration among countries in the context of international fisheries agreements. The FAO Technical Cooperation Programme project described in thisreport (TCP/RLA/0070) sought to assist CARICOM countries in formulating an approach to the development and management of large pelagic fisheries. The approach involved two thrusts, addressing each group of large pelagics: oceanic and coastal. For oceanic species, the need for and modes of direct involvement in the International Commission for the Conservation of Atlantic Tunas (ICCAT) were identified and explored. For coastal large pelagic species, largely within the western central Atlantic, the need for a regional arrangement emerged. This could be a subsidiary of ICCAT, or a separate entity with close collaboration if ICCAT is willing to delegate its responsibility for coastal species. The Caribbean Regional Fisheries Mechanism (CRFM), recently established by CARICOM, can play a key role in both thrusts. For oceanic species, it can coordinate and provide technical support for member-country participation in ICCAT. It can also explore possible approaches to collective representation. For coastal species, the CRFM can take the lead in establishing the regional arrangement and in pursuin g the linkages – among CARICOM members, other regional fishing countries and distant water fishing countries – that will be essential for such an arrangement to succeed. In developing the approach to management of large pelagics, the project compiled and reviewed a wide range of material on large pelagic fisheries in the Caribbean.

    Asia-Pacific Fishery Commission (APFIC) Regional Overview of the Status and Trends of Aquaculture in the Asia-Pacific Region 2016 2017

    The aquaculture production in the Asia-Pacific Region during the two year period (2012-2014) is reviewed to see how the aquaculture sector in the region performed during these 2 years. This will allow for the determination of the driving factors that are responsible of the over-all performance of the aquaculture sector. Country production data from the FAO database is the main source of the production statistics used. The over-all performance of the aquaculture sector in the region remained healthy and strong. The region remains the largest contributor to the global supply of fishery products from aquaculture farms supplying 91% of the total global supply of aquaculture products in 2014. As in the previous years, China remained the largest producing country of aquaculture products contributing 63.7 % of the total production in the region, and 58 % to the global supply. Indonesia is fast catching up with its 2014 production up by almost 50% compared to 2012. Other countries that posted modest increase in their aquaculture production between 2012 and 2104 include India (15.9%), Bangladesh (13.4%), Viet Nam (10.2%), New Zealand (9.7%) and Myanmar (8.5%). Although the volume of the production is not much and the production data are all FAO estimates, it is noteworthy to mention that the aquaculture production of Cambodia increased by 62.2% during the 2-year period. Thailand posted the largest decline (26.5%) in its production during 2012 and 2014 largely due to more than 50% decrease in the production of the white leg shrimp as it is affected by a major disease specifically the Acute Hepatopancreatic Necrosis Disease (AHPND or popularly called Early Mortality Syndrome or EMS). The aquaculture production in Malaysia, Philippines and Australia decreased as well by 17.9, 8.7 and 8.4%, respectively. The herbivorous and omnivorous freshwater (FW) fishes like the carps remained the top commodity for culture with production volume in 2014 equivalent to 41.6% of the total fish production in the region. This has increased by 10.7 % over the 2 year period. Aside from the carps, other FW fishes like the tilapias, catfishes and the FW fishes nei also posted significant increase in production. In addition, the seaweeds particularly Eucheuma in Indonesia and Japanese kelp and Gracilaria in the China sub-region showed more than 30% increase in production between 2012 and 2014. On the other hand, the production of white leg shrimp in Thailand and giant tiger prawn in Indonesia suffered significant decline of more than 30% during the 2-year period. It must be noted, however, that white leg shrimp production in other countries like in India and Indonesia remained strong with increase in annual production of more than 50%. Some important issues like the need to prevent outbreaks of diseases in aquaculture farms, the awareness and the commitment among the players to ensure the good health of the surrounding environment where the aquaculture activities are happening, the need to ensure the sustainability of the use of pelleted feeds, and the necessary preparations that have to be put in place for the future warmer climate have to be consistently in the radar screen to ensure the sustainability and the continued growth of the sector, and thereby for humanity to continue reaping the benefits that can be derived from the industry.
