This book was released on 2013 with total page 132 pages. Available in PDF, EPUB and Kindle. Book excerpt: "In 2011, the Conference on Fisheries requested FAO to prepare a report on the implementation of the 1999 FAO International Plan of Action for the Conservation and Management of Sharks by FAO Members, and the challenges Members faced when implementing the instrument. This document provides the requested review and includes information on National Plans of Action (NPOAs), for the Conservation and Management of Sharks, national fisheries regulations in general and measures applicable to sharks including research, data collection and reporting. In addition, membership of relevant regional fisheries management organizations (RFMOs) and status of adopting the Port State Measures Agreement are included. This review focuses on the 26 top shark-fishing countries, areas and territories determined as those reporting at least 1 percent of global shark catches during the decade from 2000 to 2009: Indonesia, India, Spain, Taiwan Province of China, Argentina, Mexico, the United States of America, Pakistan, Malaysia, Japan, France, Thailand, Brazil, Sri Lanka, New Zealand, Portugal, Nigeria, Iran (Islamic Republic of), the United Kingdom of Great Britain and Northern Ireland, the Republic of Korea, Canada, Peru, Australia, Yemen, Senegal and Venezuela (Bolivarian Republic of). This review also considered shark action plans and measures from the European Union (Member Organization) and ten RFMOs. Eighty-four (84) percent of the global shark catches reported to FAO from 2000 to 2009 was from the 26 top shark-fishing countries, areas and territories. Overall, global reported annual shark catches during this decade show a significant decline of almost 20 percent from about 900 000 tonnes to about 750 000 tonnes. The review shows that 18 of the 26 top shark fishing countries, areas and territories have adopted an NPOA Sharks and that an additional 5 of these countries are in the process of adopting or developing such a plan. Among the most commonly adopted management measures for sharks are shark fin measures; but other regulations have also been implemented such as closed areas and season, by-catch/discard regulations, protected species, total allowable catches (TAC) and quotas, special reporting requirements and others. Data collection and research on sharks is lacking in many regions. Overall, the reporting of shark catches to FAO has improved in the last decade. Shark catches reported at species level doubled from 14 percent in 1995 to 29 percent in 2010. Most of the top shark-fishing countries, areas and territories have taken steps to combat illegal, unreported and unregulated (IUU) fishing, either by signing the FAO Port State Measures Agreement (PSMA) (46 percent) or at least by adopting an NPOA IUU or similar plan (23 percent). Only five (20 percent) of the top 26 shark-fishing countries, areas and territories have not adopted an NPOA Sharks, signed the PSMA or implemented an NPOA IUU. Nonetheless, in quite a few countries the effective implementation of MCS schemes is problematic, often because of a lack of human and financial resources. All but one of the top shark-fishing countries, areas and territories are members of at least one RFMO. In particular, shark measures adopted by tuna bodies are binding in their areas of competence for all their member States that have not objected to the measure in question. The array of shark measures adopted by the RFMOs may vary from binding recommendations or resolutions to non-binding measures, as in the case of the Commission for the Conservation of Southern Bluefin Tuna (CCSBT). They include shark fin measures, catch and gear regulations, prohibited species, area closures, reporting requirements and research programmes. This means that in all but one area covered by RFBs there are internationally binding shark measures in place for high seas fisheries."--Publisher's description.

This book was released on 2021-07-07 with total page 93 pages. Available in PDF, EPUB and Kindle. Book excerpt: Some species and stocks of sharks, rays, skates, and chimaeras (termed shark in this review) are rapidly depleting due to climate change, land-based influences, and overfishing. These pressures, coupled with sharks’ low reproductive potential (slow growth and delayed maturation; long reproductive cycles; low fecundity; and long lifespans) place sharks in a risk profile that is more akin to mammals on land than fish in the ocean. The development of policy, and the delivery of management and conservation measures regulating the use, international trade, and capture of sharks (whether as a targeted species or as bycatch in fisheries), is hindered by gaps in basic knowledge – a knowledge that is required in order to get a clear sense of their status in real-time. Many countries are establishing or strengthening monitoring across shark value chains to overcome these shortfalls in information. This document reviews what shark fisheries data is being collected, highlighting the opportunities and constraints in collecting information on sharks in fisheries, based on practical experience. It includes information from 28 surveys across 19 countries: 9 in the Mediterranean, 5 in Africa, 3 in Asia, and 1 in Oceania. Interviews were conducted with data collectors and managers across the entirety of the survey process, while data collection variables were documented in order to inform those interested in the collection, provision, and exchange of shark information on common practices and their commonalities. The review identifies standardized information metrics which, if collected more generally, would strengthen the opportunity for harmonized reporting and cross-comparability across surveys. In addition – and in order to assess the status quo – the current data collection requirements of management measures applied to sharks by regional fisheries management organizations (RFMOs) were reviewed, including “no retention” measures. Finally, the review proposes a list of the minimum standard measurements and common life-history parameters required to support the assessment of shark stocks in fisheries.

Download or read book Analyses of Catch Data for Oceanic Whitetip and Silky Sharks Reported by Fishery Observers in the Hawaii-based Longline Fishery in 1996-2010 written by William Arthur Walsh and published by . This book was released on 2011 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: "This report presents descriptive statistical summaries and generalized linear model (GLM) analyses of catch data for oceanic whitetip shark, Carcharhinus longimanus, and silky shark, C. falciformis, in the Hawaii-based pelagic longline fishery. This paper is a collaborative effort begun at the Secretariat of the Pacific Community in New Caledonia and completed at the NOAA Fisheries Pacific Islands Fisheries Science Center in Hawaii. The data were collected by fishery observers aboard commercial vessels in 1995 - 2010. Oceanic whitetip shark mean annual nominal catch-per-unit effort (CPUE) decreased significantly from 0.428/1000 hooks in 1995 to 0.036/1000 hooks in 2010. This reflected a significant decrease in nominal CPUE on longline sets with positive catch from 1.690/1000 hooks to 0.773/1000 hooks, and a significant increase in longline sets with zero catches from 74.7 % in 1995 to 95.3 % in 2010. Oceanic whitetip shark CPUE was standardized by delta-lognormal and zero-inflated Poisson GLM methods. The latter method was employed because 90 .1 % of the longline sets caught zero oceanic whitetip sharks. Four factors (16 haul years, calendar quarters, deep-and shallow-set fishery sectors, 8 fishing regions) were significant explanatory variables in these analyses. Sea surface temperature was a significant continuous explanatory variable in a binomial GLM of the presence or absence of oceanic whitetip shark catches. The haul-year effect coefficients from these models were used to compute indices of relative abundance. The setime series were highly correlated, and each was also highly correlated with the time series of nominal CPUE. The silky shark catch data differed from the oceanic whitetip shark data in four major respects. The first was that nearly all silky sharks are caught on deep sets. The second was that most (62.5%) of the silky shark catch was taken from 0 0 to 10 0 N, although only 3.4 % of the observed fishing occurred in those latitudes. The third difference was that sample sizes were very small prior to 2000. Finally, although 46.3 % of the longline sets from 0 0 to 10 0 N caught zero silky sharks, 54.5% of the silky shark catch in these waters was taken on 11.5% of the longline sets, which caught ≥ 5 silky sharks. These differences led to use of the data from 0 0 to 10 0 N in the deep sector from 2000 to 2010 in the GLM analyses, which were fitted by delta-lognormal and quasi-Poisson (i.e., overdispersed) methods. These GLM analyses had low explanatory power. Silky shark CPUE has ranged from 0.034/1000 hooks to 1.840/1000 hooks, but with no significant trend. Therefore, it is concluded that the relative abundance of silky shark in tropical waters exploited by this fishery, particularly near the Line Islands, has remained fairly stable since 2000. This was not the case with oceanic whitetip shark, which has apparently undergone a highly significant decline in relative abundance in this fishery since 1995"--Abstract.

Book excerpt: This report, a joint project of the Center for Marine Conservation and TRAFFIC International, regarding existing international agreements that may promote the conservation of sharks. The report analyses several existing international fisheries regimes, and identifies gaps in the conservation of sharks. Gaps are of two general types - geographical and functional gaps. A comparison of the range of key species of sharks with the jurisdiction of existing fisheries management regimes reveals large gaps in some areas.

This book was released on 2009-01-01 with total page 519 pages. Available in PDF, EPUB and Kindle. Book excerpt: The fishing industry benefits the people and economies of the Pacific in various ways but the full value of these benefits is not reflected in the region's statistics. Records may be maintained but they are not complete, or accurate, or comparable. The research summarized in this report reaffirms the importance of this sector to the economies and societies of the Pacific island countries. The research reveals that the full value of fisheries is likely to have eluded statisticians, and therefore fisheries authorities, government decision makers, and donors. But its value has never escaped the fisher, fish trader, and fish processor. The difference in appreciation between public and private individuals must raise the question of whether fisheries are receiving adequate attention from the public sector---including the necessary management and protection, appropriate research, development, extension and training, and sufficient investment.
