A Blacktip Reef Shark Bite to the Hand in the Remote Solomon Islands Daniel Popa, MD, PhD; Nancy Beach, PA-C; Charlotte Sadler, MD ABSTRACT: Background Solomon Islands is a country in the South Pacific Ocean with excellent scuba diving, particularly among its remote islands that can be accessed by liveaboard dive boats. Blacktip reef sharks
The Use of Drones in Marine Animal Research
Operational Protocols for the Use of Drones in Marine Animal Research Vincent Raoult, Andrew P Colefax, Blake M. Allan, Daniele Cagnazzi, Nataly Castelblanco-Martínez, Daniel Ierodiaconou, David W. Johnston, Sarah Landeo-Yauri, Mitchell Lyons, Vanessa Pirotta, Gail Schofield, Paul A Butcher ABSTRACT: The use of drones to study marine animals shows promise for the examination of numerous

OPINION Whale Shark Conservation Hindered by Lack of Habitat Protection Published on 24. September 2020 Boldrocchi G, Bettinetti R ABSTRACT: N/A Int J Environ Sci Nat Res 26(1): IJESNR.MS.ID.556178 (2020) PDF-DOWNLOAD
Relative contribution to the shark fin trade of Indo‐Pacific and Eastern Pacific pelagic thresher sharks
Relative contribution to the shark fin trade of Indo‐Pacific and Eastern Pacific pelagic thresher sharks D. Cardeñosa, A. T. Fields, S. K. H. Shea, K. A. Feldheim, D. D. Chapman ABSTRACT: Fins from highly mobile shark species entering large shark fin trade hubs can originate from various geographical locations and stocks. Tracing fins from internationally
Forensic species identification of elasmobranchs landed in Costa Rican artisanal fisheries
Forensic species identification of elasmobranchs landed in Costa Rican artisanal fisheries Jason R.O’Bryhim, E.C.M. Parsons, Stacey L. Lance ABSTRACT: Elasmobranchs represent one of the most imperiled taxa, yet few nations have developed catch limits and no international or bilateral catch limits exist. One barrier to establishing catch limits is a lack of accurate species-specific extraction
Standardized data to support conservation prioritization for sharks and batoids
Standardized data to support conservation prioritization for sharks and batoids (Elasmobranchii) Rikke Oegelund Nielsen, Rita da Silva, Jacqueline Juergens, Johanna Staerk, Line Lindholm Sørensen, John Jackson, Simeon Quirinus Smeele, Dalia A. Conde ABSTRACT: We collated and synthesized information on 1,226 Elasmobranch species (i.e., sharks, rays, and skates) globally from a wide range of sources. We
Comparative morphology of shark pectoral fins
Comparative morphology of shark pectoral fins Sarah L. Hoffmann, Thaddaeus J. Buser, Marianne E. Porter ABSTRACT: Sharks vary greatly in morphology, physiology, and ecology. Differences in whole body shape, swimming style, and physiological parameters have previously been linked to varied habitat uses. Pectoral fin morphology has been used to taxonomically classify species and hypotheses on
The immunoglobulins of cartilaginous fishes
The immunoglobulins of cartilaginous fishes Hanover Matz, Danish Munir, James Logue, Helen Dooley ABSTRACT: Cartilaginous fishes, comprising the chimeras, sharks, skates, and rays, split from the common ancestor with other jawed vertebrates approx. 450 million years ago. Being the oldest extant taxonomic group to possess an immunoglobulin (Ig)-based adaptive immune system, examination of this group
Over 90 endangered fish and invertebrates are caught in industrial fisheries
Over 90 endangered fish and invertebrates are caught in industrial fisheries Roberson, L.A., Watson, R.A. & Klein, C.J. ABSTRACT: Industrial-scale harvest of species at risk of extinction is controversial and usually highly regulated on land and for charismatic marine animals (e.g. whales). In contrast, threatened marine fish species can be legally caught in industrial fisheries.
Uncovering the ecological roles and importance of rays
Buried in the sand: Uncovering the ecological roles and importance of rays Kathryn I. Flowers, Michael R. Heithaus, Yannis P. Papastamatiou ABSTRACT: Rays (superorder Batoidea) are the most diverse group of elasmobranchs, and many are threatened with extinction. However, there remain areas where research on the ecology of this group is lacking, from trophic interactions
When large marine predators feed on fisheries catches
When large marine predators feed on fisheries catches: Global patterns of the depredation conflict and directions for coexistence Paul Tixier, Mary‐Anne Lea, Mark A. Hindell, Dirk Welsford, Camille Mazé, Sophie Gourguet, John P. Y. Arnould ABSTRACT: The sustainable mitigation of human–wildlife conflicts has become a major societal and environmental challenge globally. Among these conflicts, large
