Range Expansion of the Whitenose Shark, Nasolamia Velox, and Migratory Movements to the Oceanic Revillagigedo Archipelago
Journal of the Marine Biological Association of the United Kingdom, page 1 of 5. # Marine Biological Association of the United Kingdom, 2017 doi:10.1017/S0025315417000108 Range expansion of the whitenose shark, Nasolamia velox, and migratory movements to the oceanic Revillagigedo Archipelago (west Mexico) frida lara-lizardi1,2, mauricio hoyos-padilla2,3, james t. ketchum2,4 and felipe galva’ n-magan~a1 1Instituto Polite´cnico Nacional, Centro Interdisciplinario de Ciencias Marinas, Av.

This study provides evidence of the occurrence of this species at the Revillagigedo Archipelago (18899′186′′N 112808′44′′W), Mexico, using acoustic telemetry and videos taken from 2014 to 2016. We report here movements from a coastal location (National Park Cabo Pulmo) to a group of oceanic islands (Revillagigedo Archipelago) by one single individual, supporting the idea of the potential connectivity of sharks between the Gulf of California and the Revillagigedo Archipelago. This report extends the known distribution of N. velox to 400 km off the mainland coast of the Americas, thereby increasing the knowledge of the distribution of a species commonly reported in fishery landings of the Eastern Pacific. -
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. -

Species Composition of the Largest Shark Fin Retail-Market in Mainland
www.nature.com/scientificreports OPEN Species composition of the largest shark fn retail‑market in mainland China Diego Cardeñosa1,2*, Andrew T. Fields1, Elizabeth A. Babcock3, Stanley K. H. Shea4, Kevin A. Feldheim5 & Demian D. Chapman6 Species‑specifc monitoring through large shark fn market surveys has been a valuable data source to estimate global catches and international shark fn trade dynamics. Hong Kong and Guangzhou, mainland China, are the largest shark fn markets and consumption centers in the world. We used molecular identifcation protocols on randomly collected processed fn trimmings (n = 2000) and non‑ parametric species estimators to investigate the species composition of the Guangzhou retail market and compare the species diversity between the Guangzhou and Hong Kong shark fn retail markets. Species diversity was similar between both trade hubs with a small subset of species dominating the composition. The blue shark (Prionace glauca) was the most common species overall followed by the CITES‑listed silky shark (Carcharhinus falciformis), scalloped hammerhead shark (Sphyrna lewini), smooth hammerhead shark (S. zygaena) and shortfn mako shark (Isurus oxyrinchus). Our results support previous indications of high connectivity between the shark fn markets of Hong Kong and mainland China and suggest that systematic studies of other fn trade hubs within Mainland China and stronger law‑enforcement protocols and capacity building are needed. Many shark populations have declined in the last four decades, mainly due to overexploitation to supply the demand for their fns in Asia and meat in many other countries 1–4. Mainland China was historically the world’s second largest importer of shark fns and foremost consumer of shark fn soup, yet very little is known about the species composition of shark fns in this trade hub2. -

Preliminary Study on Elasmobranch Species Along the Coast of Maharashtra
Preliminary study on Elasmobranch species along the coast of Maharashtra Final Report April 2019 – January 2020 Mangrove and Marine Biodiversity Conservation Foundation of Maharashtra Preliminary study on Elasmobranch species along the coast of Maharashtra Final Report April 2019 – January 2020 Project Researcher Dhanashree Bagade Marine Biologist Project Advisors N. Vasudevan Manas Manjrekar Neenu Somraj Virendra Tiwari Mangrove and Marine Biodiversity Conservation Foundation of Maharashtra Introduction: The Elasmobranchs, represented by sharks, sawfishes, skates, rays and chimaeras (Rat fishes) are an important group of demersal fishes. These fishes have a skeleton made of cartilage, instead of bone. The members of this group are characterised by having five to seven pairs of gill clefts opening individually to the exterior, rigid dorsal fins, small placoid scales embedded in the skin (sharks) or naked (rays). The teeth are in several series and the details of jaw anatomy vary between species which are useful in differentiating the Elasmobranch species. Their distribution ranges from nearshore regions to the deep oceanic waters. Some species are known to travel long distances, hence can be considered as highly migratory. Their stock can be found in more than one Exclusive Economic Zone (EEZ). They are widely distributed in the Oceans but are most diverse in the tropical and subtropical Indo- Pacific Ocean (Bonfil, 2002). Elasmobranchs species diversity in Indian seas is higher than that reported in many other tropical Indian Ocean countries like Sri lanka, Arabian Gulf, Maldives and Thailand (Akhilesh K. V et al. 2014). However, higher numbers have been reported from Indonesia (White et al., 2006; Fahmi, 2010). Chondrichthyans are one of the most vulnerable groups due to their biological characteristics such as slow growth rate, delayed maturation, long reproduction cycles and low fecundity. -

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%). -
