It is a medium-sized species to about 215 cm TL, with males reaching adulthood at about 110 cm TL. Rhynchobatus springeri closely resembles R. palpebratus in body shape and having a dark, eye-brow like marking on its orbital membrane, but differs from this species in having a lower vertebral count (113–126 vs. 130–139 total free centra), a broader preorbital snout, and more rows of white spots on the tail of adults. Other Rhynchobatus species in the region attain a much larger adult size, and have a relatively narrower snout and much higher vertebral counts.

Malaysia National Plan of Action for the Conservation and Management of Shark (Plan 2), Ministry of Agriculture and Agro- based Industry Malaysia, Putrajaya, Malaysia. 50pp SUMMARY Malaysia has been very supportive of the International Plan of Action for Sharks (IPOA-SHARKS) developed by FAO that is to be implemented voluntarily by countries concerned. This led to the development of Malaysia’s own National Plan of Action for the Conservation and Management of Shark or NPOA-Shark (Plan 1) in 2006. The successful development of Malaysia’s second National Plan of Action for the Conservation and Management of Shark (Plan 2) is a manifestation of her renewed commitment to the continuous improvement of shark conservation and management measures in Malaysia. -

1 Decline in CPUE of Oceanic Sharks In
IOTC-2009-WPEB-17 IOTC Working Party on Ecosystems and Bycatch; 12-14 October 2009; Mombasa, Kenya. Decline in CPUE of Oceanic Sharks in the Indian EEZ : Urgent Need for Precautionary Approach M.E. John1 and B.C. Varghese2 1 Fishery Survey of India, Mormugao Zonal Base, Goa - 403 803, India 2 Fishery Survey of India, Cochin Zonal Base, Cochin - 682 005, India Abstract The Catch Per Unit Effort (CPUE) and its variability observed in resources surveys reflect on the standing stock of the resource and the changes in the stock density. Data on the CPUE of sharks obtained in tuna longline survey in the Indian EEZ by Govt. of India survey vessels during 1984 – 2006 were considered in this study. A total effort of 3.092 million hooks yielded 20,884 sharks. 23 species belonging to five families were recorded. Average hooking rate was 0.68 percent which showed high degree of spatio-temporal variability. Sharp decline was observed in the hooking rate from the different regions. The trend in the CPUE is a clear indication of the decline in the abundance of sharks in the different regions of the EEZ, the most alarming scenario being on the west coast as well as the east coast, where the average hooking rate recorded during the last five years was less than 0.1 percent. It is evident from the results of the survey that the standing stock of several species of sharks in the Indian seas has declined to such levels that the sustainability of the resource is under severe stress requiring urgent conservation and management measures. -

Dipper Occasional Paper of the IUCN Species Survival Commission No. 25 IUCN The World Conservation Union Donors to the SSC Conservation Communications Programme and Elasmobranch Biodiversity, Conservation and Management: Proceedings of the International Seminar and Workshop, Sabah, Malaysia, July 1997 The IUCN/Species Survival Commission is committed to communicate important species conservation information to natural resource managers, decision-makers and others whose actions affect the conservation of biodiversity. The SSC's Action Plans, Occasional Papers, newsletter Species and other publications are supported by a wide variety of generous donors including: The Sultanate of Oman established the Peter Scott IUCN/SSC Action Plan Fund in 1990. The Fund supports Action Plan development and implementation. To date, more than 80 grants have been made from the Fund to SSC Specialist Groups. The SSC is grateful to the Sultanate of Oman for its confidence in and support for species conservation worldwide. The Council of Agriculture (COA), Taiwan has awarded major grants to the SSC's Wildlife Trade Programme and Conservation Communications Programme. This support has enabled SSC to continue its valuable technical advisory service to the Parties to CITES as well as to the larger global conservation community. Among other responsibilities, the COA is in charge of matters concerning the designation and management of nature reserves, conservation of wildlife and their habitats, conservation of natural landscapes, coordination of law enforcement efforts as well as promotion of conservation education, research and international cooperation. -

06_250317 part1-3.qxd 12/13/05 7:32 PM Page 15 Phylum Chordata Chordates are placed in the superphylum Deuterostomia. The possible rela- tionships of the chordates and deuterostomes to other metazoans are dis- cussed in Halanych (2004). He restricts the taxon of deuterostomes to the chordates and their proposed immediate sister group, a taxon comprising the hemichordates, echinoderms, and the wormlike Xenoturbella. The phylum Chordata has been used by most recent workers to encompass members of the subphyla Urochordata (tunicates or sea-squirts), Cephalochordata (lancelets), and Craniata (fishes, amphibians, reptiles, birds, and mammals). The Cephalochordata and Craniata form a mono- phyletic group (e.g., Cameron et al., 2000; Halanych, 2004). Much disagree- ment exists concerning the interrelationships and classification of the Chordata, and the inclusion of the urochordates as sister to the cephalochor- dates and craniates is not as broadly held as the sister-group relationship of cephalochordates and craniates (Halanych, 2004). Many excitingCOPYRIGHTED fossil finds in recent years MATERIAL reveal what the first fishes may have looked like, and these finds push the fossil record of fishes back into the early Cambrian, far further back than previously known. There is still much difference of opinion on the phylogenetic position of these new Cambrian species, and many new discoveries and changes in early fish systematics may be expected over the next decade. As noted by Halanych (2004), D.-G. (D.) Shu and collaborators have discovered fossil ascidians (e.g., Cheungkongella), cephalochordate-like yunnanozoans (Haikouella and Yunnanozoon), and jaw- less craniates (Myllokunmingia, and its junior synonym Haikouichthys) over the 15 06_250317 part1-3.qxd 12/13/05 7:32 PM Page 16 16 Fishes of the World last few years that push the origins of these three major taxa at least into the Lower Cambrian (approximately 530–540 million years ago). -

First collected in 1934, the broader ichthyological community have been aware of this distinctive but little known ray since the late 1990’s. Rhynchobatus cooki is the smallest of the wedgefishes (to 81 cm TL) and has the lowest vertebral count (fewer than 107 centra). It is also distinguishable from its congeners based on its long, hastate snout, very strongly undulate anterior pectoral-fin margin, coloration and aspects of its squamation. The dorsal coloration is mainly dark and distinctively marked with white blotches, spots and streaks, and has a dark cruciate marking on the interorbit and a prominent white border around the body margin. Unlike most other wedgefish species, the snout tip lacks dark blotches and there is no black pectoral-fin marking. -

Abstract Checklist of sharks, rays and chimaeras (Chondrichthyes, Elasmobranchii, Holocephali) from Mexico.— We present an annotated checklist of the species of sharks, rays and chimaeras (chondrichthyan fishes) occurring in Mexican waters, based on a thorough review of the literature and electronic database searches, examination of museum collection specimens, and unpublished records obtained during fieldwork conducted in the last four years. The checklist contains information of at least 214 species of chondrichthyan fishes that occur in Mexican marine and brackish waters, assigned to 84 genera, 40 families and 14 orders. It includes eight species of chimaeras, 95 batoids and 111 sharks. Condrichthyan fauna in Mexico is one of the richest in the world, with almost 17.3% of the known species. An additional 16 species are included as their occurrence in Mexican marine waters is probable according to distributional patterns.
