General information on the European Union’s Common Fisheries Policy and how it is applied. Links to relevant legislation, including Regulations, species protected, Total Allowable Catches, fishing techniques and other relevant information.

x FAO www.fao.org

o The Fisheries and Aquaculture Information and Statistics Service Website (http://www.fao.org/fi/website/FIRetrieveAction.do?dom=topic&fid=16000) offers information on Fisheries, Fish Utilisation, Trade & Fisheries, Fisheries Development, Fisheries Governance, Fishery Resources, Fisheries Technology, Ecosystems and Fisheries Research, among other key issues. It is possible to make a personalised query on specific fisheries resources, geographical zone and time period. Links are available to the electronic pages of the Committee on Fisheries (COFI) and its Sub-Committees on Aquaculture and Trade, including official documents and information on meetings. Information on the existing Regional Fisheries Bodies (cited in the corresponding section of this paper) can also be accessed through this website.

o Statistical collections. Global time series are available over 50 year time spans. Data from each statistical collection are available through various formats, tools and information products, such as summary tables of fishery statistics, yearbooks and online query panels. Other data collections, also fully-documented, are organised by records, Fact Sheets and maps, thus complementing the overall statistical collections.

Useful and illustrative publications such as the State of World Fisheries and Aquaculture (SOFIA), the Code of Conduct for Responsible Fisheries, Technical Guidelines for Responsible Fisheries, Fisheries Reports, International Plans of Action, Yearbooks of Fishery Statistics and Fisheries Technical Papers (FTP) can be downloaded on PDF version or ordered for delivery by mail. Among the many publications by FAO that contain information useful for making NDF on sharks, the following should be highlighted:

ƒ MUSICK, J.A. & R. BONFIL. (eds). 2005. Management techniques for elasmobranch fisheries. FAO FTP No. 474. Rome, FAO. 251pp.

The objectives of the manual are to provide the necessary information for fisheries managers to effectively address the IPOA Sharks, thus leading to sustainable shark fisheries. A step by step approach is provided to collect the information needed for proper stock assessment and sustainable shark management. Each chapter progresses from simple to more complex techniques.

ƒ KELLEHER, K. 2005. Discards in the world’s marine fisheries. An update. FAO Fisheries Technical Paper. No. 470. Rome, FAO. 131pp.

This study provides an update of the quantity of discards in the world’s marine fisheries based on a fishery-by-fishery approach.

ƒ GARCIA, S.M., A. ZERBI, C. ALIAUME, T. DO CHI & G. LASSERRE. 2003. The ecosystem approach to fisheries. Issues, terminology, principles, institutional foundations, implementation and outlook. FAO Fisheries Technical Paper. No. 443. Rome, FAO. 71 p.

An interesting study concluding that the future of the ecosystem approach to fisheries and fisheries depends on the way in which the two fundamental concepts of fisheries management and ecosystem management, and their respective stakeholders, will join efforts or collide.

ƒ FAO Marine Resources Service. Fisheries management. 1. Conservation and management of sharks. FAO Technical Guidelines for Responsible Fisheries. No. 4, Suppl. 1. Rome, FAO. 2000. 37pp.

The guidelines are intended to provide general advice and a framework for development and implementation of Shark Plans and Shark Assessment Reports prepared at national, subregional and regional levels.

ƒ SHOTTON, R. (ed.) 1999. Case studies of the management of

elasmobranch fisheries. FAO Fisheries Technical Paper. No. 378, parts 1 & 2. Rome, FAO. 1999. pp.1–479

This report, consisting of 29 studies, describes the relevant population biology, resource analyses and fishery management of elasmobranchs at regional, national and sub-regional levels. The authors further provide a descriptive and critical review of the policy setting process in relation to the elasmobranch fisheries, its successes, ongoing and unresolved problems and the nature of their weaknesses.

x Fishbase: www.fishbase.org

FROESE, R. & D. PAULY. Editors. 2007. FishBase. World Wide Web electronic publication. www.fishbase.org, version (08/2007).

A user-friendly database containing basic information on 30,000 fish species (including sharks) and 259,300 common names, based on 40,200 scientific references, being continuously updated by 1,480 collaborators. Information sheets

for each species comprise synonyms, common names, distribution (including maps), images, taxonomy, maximum size, environment, climate, importance, morphology, biology, red list status and, more important still, information on resilience and reproduction, when available. It also offers useful resources such as an e-book, field guides and identification keys, as well as useful on-line tools for biogeographic modelling, length-frequency relationships, life-history and point data distribution maps.

x IUCN Red List of Threatened Species: www.iucnredlist.org

IUCN Red List assessments attempt to address the global status of a species, synthesising information on all known populations. Currently, the List recognises 126 shark species as threatened. As a complementary approach, IUCN has created, through its Species Survival Commission (SSC, a science-based network of volunteer experts), the Shark Specialist Group (SSG).

x IUCN/SSC Shark Specialist Group

http://www.flmnh.ufl.edu/fish/organizations/ssg/ssg.htm

Among other valuable information on the SSG activities and research, the website makes available the following publication:

FOWLER, S.L., CAVANAGH, R.D., CAMHI, M., BURGESS, G.H., CAILLIET, G.M., FORDHAM, S.V., SIMPFENDORFER, C.A., MUSICK, J.A.(comp.&ed.).2005. Sharks, rays and chimaeras: the status of the chondrichthyan fishes. Status survey. IUCN/SSC Shark Specialist Group. IUCN, Gland, Switzerland and Cambridge. U.K. 461pp. This Status Survey is a comprehensive resource documenting the biology, threats, and opportunities for global action for the conservation of chondrichthyan fishes. The Survey arose out of widespread concern that many populations are in serious decline worldwide, resulting from expanding exploitation largely in the absence of fisheries management, conservation measures, or reliable data to guide sustainable fisheries. Its eight chapters include information on taxonomy, biology, and life history; the products, trade, and economics of exploitation; regional reports summarising shark fisheries from nine geopolitical SSG regions and their fishing nations; and status assessments for more than one hundred shark species.

x Western Pacific Regional Fishery Management Council

o GILMAN, E., S. CLARKE, N. BROTHERS, J. ALFARO-SHIGUETO, J. MANDELMAN, J. MANGEL, S. PETERSEN, S. PIOVANO, N. THOMSON, P. DALZELL, M. DONOSO, M. GOREN & T. WERNER. 2007. Shark Depredation and Unwanted Bycatch in Pelagic Longline Fisheries: Industry Practices and Attitudes, and Shark Avoidance Strategies. Western Pacific Regional Fishery Management Council, Honolulu, USA. 203pp.

In some pelagic longline fisheries, shark interactions pose substantial economic, ecological and social problems. Information on existing fisher knowledge and new strategies for shark avoidance is presented. This project collected information from a diverse range of pelagic longline fisheries in eight countries (Australia, Chile, Fiji, Italy, Japan, Peru, South Africa, USA). The main purpose is to benefit sharks and fishers wanting to reduce shark interactions, by providing the industry and management authorities with better information to manage these problems.

x Shark identification guides. There are numerous identification guides specialised in sharks, some developed by scientists, others by State Governments and others by fisheries research bodies. Among the many available, FAO has developed a catalogue on sharks of the World and three regional shark identification guides. They
