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.

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.

Predictions of southern migration timing in coastal sharks under future ocean warming. [PDF]

Conserv Biol
Abstract Projected redistribution of marine species due to ocean warming may undermine current conservation efforts. Yet, there have been few studies on how ocean warming may alter migration timing. Across 5 years of acoustic telemetry data (2018–2022), we determined environmental drivers of southward migration timing for 6 migratory shark species from

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.

Stereo videography reveals fragility in a high value thresher shark population

Frontiers in Marine Science
Population risk assessments are important tools for understanding the sustainability of shark populations and informing their conservation. In the Philippines, policy makers have made inroads to progress legislative protection for sharks in recent years,

Growth estimates of pelagic thresher shark (Alopias pelagicus Nakamura, 1935) in the Indian Ocean Southern Java waters

IOP Conference Series: Earth and Environmental Science, 2021
Abstract Alopias pelagicus were highly migratory species, oceanic and almost always found in tropical and temperate seas. This species was particularly vulnerable to exploitation of both targets and side catches. Research was conducted in May 2015 to November 2016 at the landing site of the Cilacap Fishing Port.

Exploring practical conservation measures for pelagic thresher sharks using local knowledge in Sunda Banda seascape

Frontiers in Ocean Sustainability
The pelagic thresher shark (Alopias pelagicus) is an evolutionarily distinct and globally endangered species, with population declines primarily attributed to targeted fishing and bycatch in both small-scale and industrial fisheries. As the world's largest shark fishing nation, Indonesia is a global priority for pelagic thresher shark conservation ...

Rapid DNA/eDNA-Based ID Tools for Improved Chondrichthyan Monitoring and Management. [PDF]

Mol Ecol Resour
ABSTRACT Rapid DNA/eDNA‐based ID tools, which detect specific genetic patterns without requiring sequencing, are essential for biodiversity and wildlife trade monitoring, particularly for species of conservation concern. However, the practical application of these methods remains limited by the availability of standardised protocols, accessibility of ...

Identifying spatial movements and residency of pelagic thresher sharks (Alopias pelagicus) using satellite and passive acoustic telemetry to inform local conservation in central Indonesia

Frontiers in Fish Science
The pelagic thresher shark (Alopias pelagicus) is globally endangered, threatened by bycatch, and targeted in industrial and artisanal fisheries in Indonesia. However, a lack of information about their ecology, particularly movement and habitat use, hinders the development of science-based conservation measures to protect the species.

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 ...
