Book (series)The state of world highly migratory, straddling and other high seas fishery resources and associated species 2006
Also available in:
No results found.This document describes highly migratory fish stocks, straddling fish stocks, and stocks of other high seas fishery resources and the fisheries for them, including information on their state of exploitation. Fisheries for highly migratory species are important in all oceans and semi-enclosed seas, except for polar regions. Fisheries for straddling fish stocks are much more localized, primarily occurring in a few regions where continental shelves extend beyond the 200 miles Exclusive Economic Zon e while most fisheries for other high seas fishery resources are deep-water fisheries. Formal assessments are lacking for most of the stocks examined. Nevertheless, the compilation of available assessments and FAO’s analyses indicate that about 30 percent of the stocks of highly migratory tuna and tuna-like species, more than 50 percent of the highly migratory oceanic sharks and nearly two-thirds of the straddling stocks and the stocks of other high seas fishery resources are overexploited or de pleted. The stocks concerned represent only a small fraction of the world fishery resources, but are key indicators of the state of an overwhelming part of the ocean ecosystem which appears to be more overexploited than EEZs. The scarcity of the information available and the short time elapsed since the entering into force of the UN Fish Stock Agreement does not allow for a realistic assessment of the impact it may have had on the state of the various fish stocks being exploited in the high seas . Some key issues on which progress and improvements are needed are addressed, including those regarding fisheries in the high seas for resources other than straddling stocks and highly migratory species. -
Book (series)Tilapias as alien aquatics in Asia and the Pacific: a review 2004
Also available in:
No results found.Tilapias are not native to Asia but have been a significant component of inland fisheries and aquaculture in the region for over half a century. They have been introduced into over 90 countries worldwide, with a global distribution second only to common carp. The contribution of tilapias to global aquaculture production has increased over the past three decades with production in 2002 exceeding 1.5 million tonnes with an estimated value of US$1.8 billion. The average annual growth rate in aquacu lture and capture fisheries production of tilapias from 1970 to 2002 has been 13.2 percent and 3.5 percent, respectively. In the present context of development, success of a species is determined not only by its contribution to production per se, but also by its social, cultural, economic and environmental impacts. Although tilapia has been associated with adverse environmental impacts, detailed analysis of the literature suggested that other factors, such as overfishing, environmental degradati on from land-based activities, and changes in hydrological regime have probably been more responsible for adverse impacts. It is clear that numerous factors working together can impact biodiversity. It is also clear that tilapias, as a group of alien species, have made a significant contribution to food production, poverty alleviation and livelihoods support in Asia and the Pacific. In spite of the wide-scale introduction into Asian waters, there is scant explicit evidence to indicate that tila pias have been overly destructive environmentally. -
Book (series)Management of large pelagic fisheries in CARICOM countries 2004
Also available in:
No results found.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.
