Risks to biodiversity and coastal livelihoods from artisanal elasmobranch fisheries

Risks to biodiversity and coastal livelihoods from artisanal elasmobranch fisheries in a Least Developed Country: The Gambia (West Africa) Alec B. M. Moore, Bernard Séret, Roy Armstrong ABSTRACT: Developing nations in tropical regions harbour rich biological resources on which humans depend for food, income and employment, yet data to aid their management is often lacking.

Skeletal kinematics of the hyoid arch in the suction-feeding shark Chiloscyllium plagiosum

Skeletal kinematics of the hyoid arch in the suction-feeding shark Chiloscyllium plagiosum

Skeletal kinematics of the hyoid arch in the suction-feeding shark Chiloscyllium plagiosum Bradley Scott, Cheryl A. D. Wilga, Elizabeth L. Brainerd ABSTRACT: White-spotted bamboo sharks, Chiloscyllium plagiosum, generate strong suction-feeding pressures that rival the highest levels measured in ray-finned fishes. However, the hyostylic jaw suspension of these sharks is fundamentally different from the actinopterygian mechanism,

Trends in global shark attacks

Trends in global shark attacks

Trends in global shark attacks Stephen R. Midway, Tyler Wagner, George H. Burgess ABSTRACT: Shark attacks are a global phenomenon that attracts widespread attention and publicity, often with negative outcomes for shark populations. Despite the widespread perceptions of shark attacks, trends in human water activities and shark populations are both dynamic, resulting in variable rates

Inter-individual differences in ontogenetic trophic shifts among three marine predators

Inter-individual differences in ontogenetic trophic shifts among three marine predators

Inter-individual differences in ontogenetic trophic shifts among three marine predators Philip Matich, Jeremy J. Kiszka, Michael R. Heithaus, Baptiste Le Bourg, Johann Mourier ABSTRACT: Ontogenetic niche shifts are widespread. However, individual differences in size at birth, morphology, sex, and personalities can cause variability in behavior. As such, inherent inter-individual differences within populations may lead to

A Perspective on Future Tiger Shark Research

A Perspective on Future Tiger Shark Research

A Perspective on Future Tiger Shark Research Kim N. Holland, James M. Anderson, Daniel M. Coffey, Bonnie J. Holmes, Carl G. Meyer, Mark A. Royer ABSTRACT: This “Perspectives” paper identifies aspects of tiger shark (Galeocerdo cuvier) biology that are currently unknown or for which additional data are needed to improve interpretive power. Some of these

Disappearance of white sharks leads to the novel emergence of an allopatric apex predator

Disappearance of white sharks leads to the novel emergence of an allopatric apex predator

Disappearance of white sharks leads to the novel emergence of an allopatric apex predator, the sevengill shark Neil Hammerschlag, Lacey Williams, Monique Fallows, Chris Fallows ABSTRACT: Despite global declines of apex predatory sharks, evidence for ecosystem consequences remains limited and debated. This is likely a result of both the logistical difficulties of measuring such processes

Shark aggregation and tourism near the Israeli Mediterranean coast

Shark aggregation and tourism near the Israeli Mediterranean coast

Shark aggregation and tourism: opportunities and challenges of an emerging phenomenon Z. Zemah Shamir, S. Zemah Shamir, D. Tchernov, A. Scheinin, N. Becker ABSTRACT: In the last few winters, shark communities have been aggregating near the Israeli Mediterranean coast, at a specific point, near Hadera power station. This unusual phenomenon has fascinated residents, visitors, kayakers,

Clasper Morphology of the Japanese Sawshark

Clasper Morphology of the Japanese Sawshark

Clasper Morphology of the Japanese Sawshark, Pristiophorus japonicus Günther, 1870 (Chondrichthyes: Elasmobranchii) Renan A. Moreira, Marcelo R. de Carvalho ABSTRACT: Sawsharks (Pristiophoriformes) are slender, medium‐sized sharks with elongated, saw‐like snouts, and include the monotypic Pliotrema and Pristiophorus with seven species. The phylogenetic position of sawsharks is still problematic as phylogenetic hypotheses based on morphological and

Using DNA Barcoding to Investigate Patterns of Species Utilisation in UK Shark Products

Using DNA Barcoding to Investigate Patterns of Species Utilisation in UK Shark Products

Using DNA Barcoding to Investigate Patterns of Species Utilisation in UK Shark Products Reveals Threatened Species on Sale Catherine A. D. Hobbs, Robert W. A. Potts, Matthew Bjerregaard Walsh, Jane Usher, Andrew M. Griffiths ABSTRACT: Many shark populations are in decline, primarily due to overexploitation. In response, conservation measures have been applied at differing scales,

Effects of on-deck holding conditions and air exposure on post-release behaviours of sharks revealed by a remote operated vehicle

Effects of on-deck holding conditions and air exposure on post-release behaviours of sharks revealed by a remote operated vehicle

Effects of on-deck holding conditions and air exposure on post-release behaviours of sharks revealed by a remote operated vehicle Vincent Raoult, Jane E.Williamson, Timothy M.Smith, Troy F.Gaston ABSTRACT: While post-release mortality estimates have been conducted on a range of shark species, the short-term sub-lethal effects of capture, handling and release are poorly known and have

Bycatch and discarding patterns of dogfish and sharks taken in English and Welsh commercial fisheries

Bycatch and discarding patterns of dogfish and sharks taken in English and Welsh commercial fisheries

Bycatch and discarding patterns of dogfish and sharks taken in English and Welsh commercial fisheries Joana F. Silva, Jim R. Ellis ABSTRACT: At‐sea observer programmes can provide spatio‐temporal data on the sizes and quantities of fish being either discarded or retained, including for species and size categories that may not be sampled effectively during scientific

Reproductive philopatry in a coastal shark drives age-related population structure

Reproductive philopatry in a coastal shark drives age-related population structure Juliana D. Klein, Aletta E. Bester-van der Merwe, Matt L. Dicken, Kolobe L. Mmonwa, Peter R. Teske ABSTRACT: The cosmopolitan lamniform shark Carcharias taurus (commonly known as the ragged-tooth, grey nurse or sand tiger shark) is threatened by overexploitation in parts of its range. Return

Molecular tools for identification of shark species involved in depredation incidents

Molecular tools for identification of shark species involved in depredation incidents in Western Australian fisheries Seema Fotedar, Sherralee Lukehurst, Gary Jackson, Michael Snow ABSTRACT: Shark depredation is an issue of concern in some Western Australian recreational and commercial fisheries where it can have economic, social and ecological consequences. Knowledge of the shark species involved is
