Genetic diversity and population structure of the pelagic thresher shark (Alopias pelagicus) in the Pacific Ocean: evidence for two evolutionarily significant units. [PDF]

PLoS ONE, 2014
There has been an increasing concern about shark overexploitation in the last decade, especially for open ocean shark species, where there is a paucity of data about their life histories and population dynamics.

Depth and temperature profiles reflect individual differences in the daytime diving behaviours of pelagic thresher sharks

Frontiers in Marine Science, 2023
We used acoustic telemetry to investigate the roles of depth and temperature in the daytime foraging behaviours of 13 tagged pelagic thresher sharks by monitoring their fine scale vertical movements in the Philippines.

Data‐limited approach to the management and conservation of the pelagic thresher shark in the Northwest Pacific

Conservation Science and Practice, 2022
The pelagic thresher shark is among the most heavily exploited shark species in the commercial fisheries of the tropical Indo‐Pacific oceans. Despite this severe exploitation, little is known about pelagic thresher population dynamics, particularly the ...

Vertical movements of a pelagic thresher shark (Alopias pelagicus): insights into the species’ physiological limitations and trophic ecology in the Red Sea [PDF]

Endangered Species Research, 2020
The pelagic thresher shark Alopias pelagicus is an understudied elasmobranch harvested in commercial fisheries of the tropical Indo-Pacific. The species is endangered, overexploited throughout much of its range, and has a decreasing population trend ...

Genetic identification of three CITES-listed sharks using a paper-based Lab-on-a-Chip (LOC). [PDF]

PLoS ONE
Threatened shark species are caught in large numbers by artisanal and commercial fisheries and traded globally. Monitoring both which shark species are caught and sold in fisheries, and the export of CITES-restricted products, are essential in reducing ...

Trophic Ecology during the Ontogenetic Development of the Pelagic Thresher Shark Alopias pelagicus in Baja California Sur, Mexico

Diversity, 2023
The trophic ecology of the Pelagic Thresher shark (Alopias pelagicus) was evaluated based on chemical ecology using stable isotope ratios of carbon (δ13C) and nitrogen (δ15N) in the vertebrae and muscles.

Parasite community of the pelagic thresher Alopias pelagicus (Lamniformes) as additional indicator of trophic network status and functioning [PDF]

Scientific Reports
The majority of marine parasites are trophically transmitted, exhibiting a complex life cycle, thus, parasite communities investigation is a valuable source of information on trophic network status.

Oceanic sharks clean at coastal seamount. [PDF]

PLoS ONE, 2011
Interactions between pelagic thresher sharks (Alopias pelagicus) and cleaner wrasse were investigated at a seamount in the Philippines. Cleaning associations between sharks and teleosts are poorly understood, but the observable interactions seen at this ...

Vulnerability Assessment of Pelagic Sharks in the Western North Pacific by Using an Integrated Ecological Risk Assessment

Animals, 2021
The vulnerability of 11 pelagic shark species caught by the Taiwanese coastal and offshore longline fisheries in the western North Pacific were assessed by an ecological risk assessment (ERA) and 10 of the 11 species was assessed by using an integrated ...
