This report describes the population biology and fishery management of elasmobranchs at regional, national and sub-regional levels - in Atlantic Europe, the United States, the Caribbean, Guatemala, South Africa, Uruguay, the Falkland Islands, the Seychelles, two states in India, the Maldives, Malaysia, Australia, New Zealand, Japan, Fiji and Ecuador. Regional accounts are given of management of Galeorhinus galeus, deepwater sharks and elasmobranch considerations of a tuna commission. NGO elasmobranch activities are described and an analysis of the quality of the relevant data in the FAO Nominal Catches and Landings Data Base. The topics of the resource, fishery and associated species, current status of fisheries and harvesting processes are described together with the evolution of the catch, fleet, fishing effort, commerce, fishery markets and revenues from the fishery. Comments on the economics of the fishery and nature of the workforce are also given. In relation to fisheries administration, management objectives and national fisheries policies are described and the manner of the planning process. Where applicable, the objectives setting process, relevant stakeholders and the handling of management negotiations are noted. The nature of gear restrictions and their effectiveness together with vessel regulations and where they exist, on catch, closed seasons, effort limitations, etc., are described Where management planning occurs, the provision of resource management advice together with a description of the departments involved and management activities are described. Several papers review stock assessment activities plus descriptions and analyses of the biological advice review process with comments on the sustainability of the resource. National accounts describe the relevant law and enforcement processes. The report consists of two parts.

The Darwin Elasmobranch Biodiversity Conservation and Management project in Sabah held a three-day international seminar that included a one-day workshop in order to highlight freshwater and coastal elasmobranch conservation issues in the region and worldwide, to disseminate the result of the project to other Malaysian states and countries, and to raise awareness of the importance of considering aspects of elasmobranch biodiversity in the context of nature conservation, commercial fisheries management, and for subsistence fishing communities. These proceedings contain numerous peer-reviewed papers originally presented at the seminar, which cover a wide range of topics, with particular reference to species from freshwater and estuarine habitats. The workshop served to develop recommendations concerning the future prospects of elasmobranch fisheries, biodiversity, conservation and management. This paper records those conclusions, which highlight the importance of elasmobranchs as top marine predators and keystone species, noting that permanent damage to shark and ray populations are likely to have serious and unexpected negative consequences for commercial and subsistence yields of other important fish stocks.
"Rebuilding depleted stocks is a central part of the fisheries governance agenda. By analysing the available literature, Part 1 of "Rebuilding of marine fisheries" provides a global review of the emergence of the rebuilding paradigm, its key concepts, the trends in fishery resources, and the empirical evidence available on stocks depletion, collapse and rebuilding. It addresses the bio-ecological, economic, and human dimensions of rebuilding or restoration of stocks, multispecies assemblages and habitats/ecosystems and touches on the need for rebuilding at the whole sector level when depletion has become widespread and chronic. The human imensions of stocks and fisheries are given particular attention, looking at conflicting objectives, the bio-economy of rebuilding, its costs and benefits, and the distributional effects of the related reform among actors with their potential social consequences in the short and long terms. Governance is addressed in detail: legal and policy frameworks; rationale and objectives of a rebuilding regime; alternative rebuilding strategies; reference values and protocols; regulatory time-frames; risk management and harvest control rules; impacts of climatic oscillations; management tool-box; implementation guidance and performance evaluation. The document ends with a review of the determinants of success of a rebuilding programme."--Publisher's description for part 1.
