E-mail: [email protected] 4Corresponding author Abstract A new deep-water catshark of the genus Apristurus Garman, 1913 is described based on nine specimens from the Gulf of Aden in the northwestern Indian Ocean. Apristurus breviventralis sp. nov. belongs to the ‘brunneus group’ of the genus and is characterized by having pectoral-fin tips reaching beyond the midpoint between the paired fin bases, a much shorter pectoral-pelvic space than the anal-fin base, a low and long-based anal fin, and a first dorsal fin located behind pelvic-fin insertion. The new species most closely resembles the western Atlantic species Apristurus canutus, but is distinguishable in having greater nostril length than internarial width and longer claspers in adult males. -

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%). -
Identification Guide to the Deep-Sea Cartilaginous Fishes of the Indian
Identification Guide to the Deep–Sea Cartilaginous Fishes of the Indian Ocean Ebert, D.A. and Mostarda, E. 2013. Identification guide to the deep–sea cartilaginous fishes of the Indian Ocean. FishFinder Programme, FAO, Rome. 76 pp. Supervision: Merete Tandstad, Jessica Sanders and Johanne Fischer (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 Governments of Norway and Japan (Support to the implementation of the International Guidelines on the Management of Deep-Sea Fisheries in the High Seas and Fisheries management and marine conservation within a changing ecosystem context projects) 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). Its production is the result of a collaborative effort among scientists, fishery observers and the fishing industry who attended the FAO regional workshop held in Flic en Flac, Mauritius, from January 16 to 18, 2013. The general objective of the workshop was to discuss, share experiences and finally draft recommendations for the development of field products aimed at facilitating the identification of Indian Ocean deep-sea cartilaginous fishes. The present guide covers the deep–sea Indian Ocean, primarily FAO Fishing Areas 51 and 57, and that part of Area 47 that extends from Cape Point, South Africa to the east, e.g. -

E-mail: [email protected] *Corresponding author Abstract Sharks of the genus Apristurus from Taiwanese waters are reviewed for the first time, and incorrect scientific names and wrong taxonomic information given in the literature are corrected. After extensive examination of specimens deposited in various museums, universities and fisheries institutions in Taiwan, Japan and China, the following five species are recog- nized from Taiwanese waters: Apristurus herklotsi (Fowler, 1934), A. longicephalus Nakaya, 1975, A. gibbosus Meng, Chu & Li, 1985, A. macrostomus Chu, Meng & Li, 1985, and A. platyrhynchus (Tanaka, 1909). Apristurus herklotsi, A. longicephalus, A. gibbosus and A. macrostomus are reported from Taiwanese waters for the first time, and the presence of A. platyrhynchus is formally recognized based on a single voucher specimen. Each species is fully described, and a key to the species of Apristurus in Taiwanese waters is provided. Morphological and biological information of each species is also provided.

5Th Meeting of the Scientific Committee SC5-DW09 Rev1
5th Meeting of the Scientific Committee Shanghai, China, 23 - 28 September 2017 SC5-DW09_rev1 Ecosystem approach considerations: Deepwater chondrichthyans (sharks, rays and chimaeras) in the Western SPRFMO Area Clinton Duffy1, Shane Geange1 & Tiffany Bock2 1 Department of Conservation 2 Ministry for Primary Industries 1 23 Aug 2017 SC5-DW09_rev1 1. Purpose of paper This paper provides a characterisation of the catch of chondrichthyans in New Zealand bottom fisheries in the SPRFMO Area and information on potential risks to deepwater chondrichthyan species from SPRFMO bottom fishing. Chondrichthyans, particularly those which predominantly occur or complete most of their lifecycle below 200 m depth, are known to have life history characteristics which make them especially vulnerable to fishing pressure. 2. Background About half of chondrichthyans are considered deepwater species, of which around half are sharks (predominantly squaloid dogfishes, Order Squaliformes, and catsharks, Order Carcharhiniformes, Families Pentanchidae and Scyliorhinidae)), with the remainder being skates (predominantly Arhynchobatidae, Rajidae, and Anacanthobatidae), and holocephalans (Kyne & Simpfendorfer 2007). There are currently 177 species reported from the SPRFMO Area that are known to regularly occur below 200 m depth (Appendix 1). Chondrichthyans generally exhibit relatively slow growth rates, late age at maturity, low fecundity and low natural mortality. Knowledge of the growth and reproductive parameters of most deepwater species is generally poor or completely lacking. For the limited number of deepwater species for which sufficient life history data is available, their estimated intrinsic rebound potential values (i.e., ability of a species to recover from fishing pressure) fall at the lower end of the chondrichthyan productivity scale, and include the lowest levels observed (Kyne & Simpfendorfer 2007). -

Photo: Scott Tindale. New Zealand Threat Classification Series is a scientific monograph series presenting publications related to the New Zealand Threat Classification System (NZTCS). Most will be lists providing NZTCS status of members of a plant or animal group (e.g. algae, birds, spiders), each assessed once every 5 years. After each five-year cycle there will be a report analysing and summarising trends across all groups for that listing cycle. From time to time the manual that defines the categories, criteria and process for the NZTCS will be reviewed. Publications in this series are considered part of the formal international scientific literature. This report is available from the departmental website in pdf form.
