  • Conservation and Population Ecology of Manta Rays in the Maldives
    Conservation and Population Ecology of Manta Rays in the Maldives Guy Mark William Stevens Doctor of Philosophy University of York Environment August 2016 2 Abstract This multi-decade study on an isolated and unfished population of manta rays (Manta alfredi and M. birostris) in the Maldives used individual-based photo-ID records and behavioural observations to investigate the world’s largest known population of M. alfredi and a previously unstudied population of M. birostris. This research advances knowledge of key life history traits, reproductive strategies, population demographics and habitat use of M. alfredi, and elucidates the feeding and mating behaviour of both manta species. M. alfredi reproductive activity was found to vary considerably among years and appeared related to variability in abundance of the manta’s planktonic food, which in turn may be linked to large-scale weather patterns such as the Indian Ocean Dipole and El Niño-Southern Oscillation. Key to helping improve conservation efforts of M. alfredi was my finding that age at maturity for both females and males, estimated at 15 and 11 years respectively, appears up to 7 – 8 years higher respectively than previously reported. As the fecundity of this species, estimated at one pup every 7.3 years, also appeared two to more than three times lower than estimates from studies with more limited data, my work now marks M. alfredi as one of the world’s least fecund vertebrates. With such low fecundity and long maturation, M. alfredi are extremely vulnerable to overfishing and therefore needs complete protection from exploitation across its entire global range.

  • Before the Secretary of Commerce Petition to List the Pacific Bluefin Tuna
    Credit: aes256 [CC BY 2.1 jp] via Wikimedia Commons Before the Secretary of Commerce Petition to List the Pacific Bluefin Tuna (Thunnus orientalis) as Endangered Under the Endangered Species Act June 20, 2016 6/20/2016 EXECUTIVE SUMMARY Petitioners formally request that the Secretary of Commerce, through the National Marine Fisheries Service (NMFS), list the Pacific bluefin tuna (Thunnus orientalis) as endangered or in the alternative list the species as threatened, under the federal Endangered Species Act (ESA), 16 U.S.C. §§ 1531 – 1544. Pacific bluefin tuna are severely overfished, and overfishing continues, making extinction a very real risk. According to the 2016 stock assessment by the International Scientific Committee for Tuna and Tuna-Like Species in the North Pacific Ocean (ISC), decades of overfishing have left the population at just 2.6% of its unfished size. Recent fishing rates (2011-2013) were up to three times higher than commonly used reference points for overfishing. The population’s severe decline, in combination with inadequate regulatory mechanisms to end overfishing or reverse the decline, has pushed Pacific bluefin tuna to the edge of extinction. Pacific bluefin tuna are important apex predators in the marine ecosystem and must be conserved. They are one of three bluefin tuna species. These three species are renowned for their large size, unique physiology and biomechanics, and capacity to swim across ocean basins. They are slow-growing, long-lived, endothermic fish. The Pacific bluefin migrates tens of thousands of miles across the largest ocean to feed and spawn, ranging from waters north of Japan to New Zealand in the western Pacific and off California and Mexico in the eastern Pacific.

  • Sharks, Skates and Rays
    Common Name: Atlantic torpedo ray SPCN Scientific Name: Torpedo nobiliana Taxon: Sharks, Skates, and Rays Federal Status: Not Listed Natural Heritage Program Rank: New York Status: Not Listed Global: Not Ranked New York: Not Ranked Tracked: No Synopsis: The Atlantic torpedo ray is a species of electric ray with a wide range in the Atlantic Ocean (Notarbartolo di Sciara et al. 2009). It is a batoid fish and of the two genera and fourteen species of electric rays worldwide, it is the only one found in the Northwest Atlantic Ocean. (Bigelow and Schroeder 2002). In the western Atlantic, it can be found from Nova Scotia, Canada south to Brazil (Robins and Ray 1986,). Coastwide it is found on the continental shelf and has been seen off the south shore of Long Island in New York many times and was caught in a trawl survey in 2009 (Briggs and Waldman 2002, M. Richards, personal communication). This species is found from the surface to depths of about 800 meters; juveniles are mostly benthic (Notarbartolo di Sciara et al. 2009). Atlantic torpedo adults have been reported to migrate long distances (Notarbartolo di Sciara et al. 2009). Because there is such little catch data for this species, current trends cannot be determined (Notarbarto lo di Sciara et al. 2009).

Camhi, Sarah V. Valenti, Sonja V. Fordham, Sarah L. Fowler and Claudine Gibson This report describes the results of a thematic Red List Workshop held at the University of Oxford’s Wildlife Conservation Research Unit, UK, in 2007, and incorporates seven years (2000–2007) of effort by a large group of Shark Specialist Group members and other experts to evaluate the conservation status of the world’s pelagic sharks and rays. It is a contribution towards the IUCN Species Survival Commission’s Shark Specialist Group’s “Global Shark Red List Assessment.” The Red List assessments of 64 pelagic elasmobranch species are presented, along with an overview of the fisheries, use, trade, and management affecting their conservation. Pelagic sharks and rays are a relatively small group, representing only about 6% (64 species) of the world’s total chondrichthyan fish species. These include both oceanic and semipelagic species of sharks and rays in all major oceans of the world. No chimaeras are known to be pelagic. Experts at the workshop used established criteria and all available information to update and complete global and regional species-specific Red List assessments following IUCN protocols. These assessments were agreed upon by consensus throughout the SSG network prior to submission to the IUCN Red List of Threatened SpeciesTM.
