SC-04-19 4th Meeting of the Southern Indian Ocean Fisheries Agreement (SIOFA) Scientific Committee 25–29 March 2019, Yokohama, Japan Draft manuscript for an ecological risk assessment for the effects of bottom fishing gears on deepwater chondrichthyans in high seas areas of the Southern Indian and South Pacific oceans Relates to agenda item: 7 Working paper Info paper Delegation of Australia Abstract This paper provides a draft manuscript for an ecological risk assessment for the effects of bottom fishing gears on deepwater chondrichthyans in high seas areas of the Southern Indian and South Pacific Oceans. 1 Recommendations It is recommended that the SC: • Note that this PSA and SAFE analysis has identified a number of species of deepwater chondrichthyans at high or extreme relative vulnerability to fishing using demersal trawl, midwater trawl, demersal longline and demersal gillnet gears; • Note that a number of these species assessed to be at the high or extreme vulnerability are taken in association with commercial deepwater shark fisheries; • Note there is limited catch, effort and biological information for many species of deepwater chondrichthyan; • Note that some species of deepwater chondrichthyans are highly vulnerable to overfishing due to their life history characteristics; and • Recommend to the Meeting of the Parties that stock assessment for species of deepwater chondrichthyans taken in association with commercial deepwater shark fisheries is urgently required to estimate sustainable yields and mitigate the potential for overexploitation that has been seen in similar fisheries globally. 2 Ecological risk assessment for the effects of bottom fishing gears on deepwater chondrichthyans in high seas areas of the Southern Indian and South Pacific oceans L. -
Identification Guide to the Deep-Sea Cartilaginous Fishes Of
Identification guide to the deep–sea cartilaginous fishes of the Southeastern Atlantic Ocean FAO. 2015. Identification guide to the deep–sea cartilaginous fishes of the Southeastern Atlantic Ocean. FishFinder Programme, by Ebert, D.A. and Mostarda, E., Rome, Italy. Supervision: Merete Tandstad, Jessica Sanders (FAO, Rome) Technical editor: Edoardo Mostarda (FAO, Rome) Colour illustrations, cover and graphic design: Emanuela D’Antoni (FAO, Rome) This guide was prepared under the “FAO Deep–sea Fisheries Programme” thanks to a generous funding from the Government of Norway (Support to the implementation of the International Guidelines on the Management of Deep-Sea Fisheries in the High Seas project) for the purpose of assisting states, institutions, the fishing industry and RFMO/As in the implementation of FAO International Guidelines for the Management of Deep-sea Fisheries in the High Seas. It was developed in close collaboration with the FishFinder Programme of the Marine and Inland Fisheries Branch, Fisheries Department, Food and Agriculture Organization of the United Nations (FAO). The present guide covers the deep–sea Southeastern Atlantic Ocean and that portion of Southwestern Indian Ocean from 18°42’E to 30°00’E (FAO Fishing Area 47). It includes a selection of cartilaginous fish species of major, moderate and minor importance to fisheries as well as those of doubtful or potential use to fisheries. It also covers those little known species that may be of research, educational, and ecological importance. In this region, the deep–sea chondrichthyan fauna is currently represented by 50 shark, 20 batoid and 8 chimaera species. This guide includes full species accounts for 37 shark, 9 batoid and 4 chimaera species selected as being the more difficult to identify and/or commonly caught. -

Abstract Proteoglycans (PGs) were isolated from deep sea shark Echinorhinus brucus (bramble shark) cartilage and their anti-proliferative activity against MCF-7 cell lines was evaluated. To establish apoptosis involvement for cytotoxicity, the following assays were performed i.e., caspases 3 and 9 assay, double fluorescent staining and DNA laddering assay. -
Tropical Eastern Pacific Records of the Prickly Shark, Echinorhinus Cookei
Tropical Eastern Pacific Records of the Prickly Shark, Echinorhinus cookei (Chondrichthyes: Echinorhinidae)1 Douglas J. Long,2,3,5 John E. McCosker,3 Shmulik Blum,4 and Avi Klapfer4 Abstract: Most records of the prickly shark, Echinorhinus cookei Pietschmann, 1928, are from temperate and subtropical areas of the Pacific rim, with few rec- ords from the tropics. This seemingly disjunct distribution led some authors to consider E. cookei to have an antitropical distribution. Unreported museum spec- imens and underwater observations of E. cookei from Cocos Island, Costa Rica; the Galápagos Islands; and northern Peru confirm its occurrence in the trop ical eastern Pacific and, combined with other published records from the eastern Pacific, establish a continuous, panhemispheric eastern Pacific distribution. The genus Echinorhinus contains two spe- Mundy [1994] and Crow et al. [1996]); it has cies, the bramble shark, E. brucus (Bonnaterre, subsequently been collected or observed off 1788), from the Atlantic, Mediterranean, Japan (Taniuchi and Yanagisawa 1983, Ko- western Indian Ocean, and Australia, New bayashi 1986), Taiwan (Teng 1958), Palau Zealand, and Japan, and the prickly shark, (Saunders 1984), Tonga (Randall et al. 2003), E. cookei Pietschmann, 1928, known from New Caledonia (Fourmanoir 1979), New Hawai‘i and the western and eastern Pacific Zealand (Garrick 1960, Garrick and More- Ocean (Compagno et al. 2005, Last and Ste- land 1968), northeastern and southeastern vens 2009).

NEA Shark Covers
This report describes the results of a regional Red List Workshop held at the Joint Nature Conservation Committee (JNCC), Peterborough, UK, in 2006, as a contribution towards the IUCN Species Survival Commission’s Shark Specialist Group’s ‘Global Shark Red List Assessment’. The purpose of the workshop was to assess the conservation status of the chondrichthyan fishes (sharks, rays and chimaeras) of the Northeast Atlantic region (FAO Major Fishery Area 27). This region is bordered by some of the largest and most important chondrichthyan fishing nations in the world, including Spain, France, the UK and Portugal. A regional overview of fisheries, utilisation, trade, management and conservation is also presented. The Northeast Atlantic chondrichthyan fauna is moderately diverse, with an estimated 118 species (approximately 11% of total living chondrichthyans). These occur within a huge range of habitats, including the deep-sea, open oceans, and coastal waters from the Arctic to the Mediterranean. During the workshop, experts collated information and prepared 74 global and 17 regional species assessments, thereby completing the Red Listing process for the described chondrichthyan fauna of the Northeast Atlantic (two undescribed species were not assessed). These assessments were agreed by consensus throughout the SSG network prior to their submission to IUCN Red List of Threatened SpeciesTM. Results show that 26% of Northeast Atlantic chondrichthyans are threatened within the region (7% Critically Endangered, 7% Endangered, 12% Vulnerable). A further 20% are Near Threatened, 27% Least Concern and 27% are Data Deficient. This is a significantly higher level of threat than that for the whole taxonomic group, worldwide. Globally, of the 1, 038 species of chondrichthyans assessed, 18% are threatened (3% CR, 4% EN, 11% VU), 13% are Near Threatened, 23% Least Concern and 46% Data Deficient. -

Tewes, Kulka, D.W. Graham, R.T. Bizzarro, J.J. Fordham, Ebert, S.V. Carlson, D.A. J.K. Kyne, P.M. Edited by and Caribbean Chondrichthyans Executive Summary This report from the IUCN Shark Specialist Group includes the first compilation of conservation status assessments for the 282 chondrichthyan species (sharks, rays, and chimaeras) recorded from North American, Central American, and Caribbean waters. The status and needs of those species assessed against the IUCN Red List of Threatened Species criteria as threatened (Critically Endangered, Endangered, and Vulnerable) are highlighted. An overview of regional issues and a discussion of current and future management measures are also presented. A primary aim of the report is to inform the development of chondrichthyan research, conservation, and management priorities for the North American, Central American, and Caribbean region. Results show that 13.5% of chondrichthyans occurring in the region qualify for one of the three threatened categories. These species face an extremely high risk of extinction in the wild (Critically Endangered; 1.4%), a very high risk of extinction in the wild (Endangered; 1.8%), or a high risk of extinction in the wild (Vulnerable; 10.3%).
