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 [PDF]

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 ...

An ecosystem approach to manage pelagic thresher shark (Alopias pelagicus) based in Kutaraja Ocean Fishing Port, Aceh

Depik Jurnal, 2022
Sharks is the dominant bycatch of purse seine and bottom longline vessels that landed in Kutaraja ocean fishing port, particularly pelagic thresher shark species (Alopias pelagicus).

Trophic shift in the diet of the pelagic thresher shark based on stomach contents and stable isotope analyses [PDF]

Marine Biology Research, 2013
The trophic ecology of the pelagic thresher shark (Alopias pelagicus) was analysed using stomach contents and carbon (δ13C) and nitrogen (δ15N) stable isotope analysis. The sharks were caught in Ecuadorian waters between June and December 2003. Approximately 24 prey species were found in the stomachs of 111 sharks.

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 ...

Organic and Inorganic Pollutants, Oxidative Stress Biomarkers, and Electrophoretic Protein Profiles in an Endangered Thresher Shark (Alopias vulpinus) From Southeastern Brazil: A Case Study. [PDF]

Environ Toxicol
ABSTRACT A comprehensive screening of different environmental contaminants (total metals, thermostable metal fractions associated with detoxification, and persistent organic pollutants) was conducted in an endangered common thresher shark (Alopias vulpinus ) individual incidentally captured in southeastern Brazil.

Beyond the Meal: Trophic Controls by Pelagic and Demersal Chondrichthyes in Two Different Mediterranean Marine Food Webs. [PDF]

Ecol Evol
Pelagic and demersal sharks played different top‐down controls in the food web. Pelagic sharks act as apex predators impacting mesoconsumers. Trophic controls patterns by demersal sharks change according to ecosystem traits. ABSTRACT Pelagic and demersal Chondrichthyes can assume different patterns of trophic controls on marine food webs, sustaining ...

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.
