However, their the increasing demand for their gill plates, which are used as a pseudo-medicinala health tonic in China. To assess the trade in dried mobulid gill plates (product name ‘Peng Yu Sai’), and its potential impact on populations of these highly vulnerable species, WildAid researchers conducted market surveys throughout Southeast Asia in 2009-10.This research, compiled in our 2011 report The Global Threat to Manta and Mobula Rays(1), plate trade, representing over 99% of the market. In 2013, the same markets in and begin to gauge market trends. Dried gill plate samples were also purchased and tested for heavy metal contamination. Additionally, in 2014 two baseline complete understanding of Peng Yu Sai Our 2013 estimates reveal a market that has increased by 168% in value in only three years, representing a near threefold increase in mobulids taken, despite the listing of manta rays on Appendix II of the Convention on International Trade in Endangered Species (CITES). -

ABSTRACT Draft identification guide for species of Mobulidae family, which is commonly observed as by-catch in tuna associated fishery in the region is presented. INTRODUCTION Species of Mobulidae family are a common bycatch occurs in the pelagic tuna fisheries of the Indian Ocean both in the industrial (purse seine and longline) and artisanal (gillnets) sector (Romanov 2002; White et al., 2006; Romanov et al., 2008). Apparently these species also subject of overexploitation: most of Indian Ocean species marked as vulnerable or near threatened at the global level, however local assessment are often not exist (Table).

Prionace Glauca) Across Their Life History
Movements of Blue Sharks (Prionace glauca) across Their Life History Frederic Vandeperre1,2*, Alexandre Aires-da-Silva3, Jorge Fontes1,2, Marco Santos1,2, Ricardo Serra˜o Santos1,2, Pedro Afonso1,2 1 Centre of IMAR of the University of the Azores; Department of Oceanography and Fisheries, Horta, Portugal, 2 LARSyS Associated Laboratory, Lisboa, Portugal, 3 Inter- American Tropical Tuna Commission, La Jolla, California, United States of America Abstract Spatial structuring and segregation by sex and size is considered to be an intrinsic attribute of shark populations. These spatial patterns remain poorly understood, particularly for oceanic species such as blue shark (Prionace glauca), despite its importance for the management and conservation of this highly migratory species. This study presents the results of a long- term electronic tagging experiment to investigate the migratory patterns of blue shark, to elucidate how these patterns change across its life history and to assess the existence of a nursery area in the central North Atlantic. Blue sharks belonging to different life stages (n = 34) were tracked for periods up to 952 days during which they moved extensively (up to an estimated 28.139 km), occupying large parts of the oceanic basin. Notwithstanding a large individual variability, there were pronounced differences in movements and space use across the species’ life history. The study provides strong evidence for the existence of a discrete central North Atlantic nursery, where juveniles can reside for up to at least 2 years. In contrast with previously described nurseries of coastal and semi-pelagic sharks, this oceanic nursery is comparatively vast and open suggesting that shelter from predators is not its main function. -

The study of the Portuguese marine ichthyofauna has a long historical tradition, rooted back in the 18th Century. Here we present an annotated checklist of the marine fishes from Portuguese waters, including the area encompassed by the proposed extension of the Portuguese continental shelf and the Economic Exclusive Zone (EEZ). The list is based on historical literature records and taxon occurrence data obtained from natural history collections, together with new revisions and occurrences. -

CONCERTED ACTION for the MOBULID RAYS (MOBULIDAE)1 Adopted by the Conference of the Parties at Its 13Th Meeting (Gandhinagar, February 2020)
CONVENTION ON UNEP/CMS/Concerted Action 12.6 (Rev.COP13) MIGRATORY Original: English SPECIES CONCERTED ACTION FOR THE MOBULID RAYS (MOBULIDAE)1 Adopted by the Conference of the Parties at its 13th Meeting (Gandhinagar, February 2020) The Concerted Action for Mobulid Rays was first adopted at the 12th Meeting of the Conference of the Parties (UNEP/CMS/COP12/Concerted Action 12.6). A report on implementation was submitted to the 13th Meeting of the Parties (COP13) together with a proposal for extension and revision (UNEP/CMS/COP13/Doc.28.1.6), which was approved by the Parties. (i). Proponents: The Manta Trust The Manta Trust is an international organization that takes a multidisciplinary approach to the conservation of Manta spp. and Mobula spp. Mobulid rays and their habitats through conducting robust science and research, raising awareness and educating the general public and community stakeholders. The Manta Trust network extends across the globe, including collaborations and affiliated projects in over 25 countries and mobulid Range States. The Manta Trust is a Cooperating Partner to the CMS Sharks MOU. Wildlife Conservation Society (WCS) The Wildlife Conservation Society is an international conservation organization working to save wildlife and wild places worldwide through science, conservation action, education, and inspiring people to value nature. WCS works across the globe in more than 60 countries, and the WCS Marine Conservation Program works in more than 20 countries to protect key marine habitats and wildlife, end overfishing, and protect key species, including sharks and rays. WCS is a founding partner of the Global Sharks and Rays Initiative (GSRI), which is implementing a global ten-year strategy that aims to: save shark and ray species from extinction; transition shark and ray fisheries to sustainability; effectively control international trade in shark and ray parts and products; and reduce consumption of shark and ray products from illegal or unsustainable sources.
