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 ...

Cleaner wrasse forage on ectoparasitic digeneans (phylum Platyhelminthes) that infect pelagic thresher sharks (Alopias pelagicus) [PDF]

Marine Biodiversity, 2014
The cleaning system is a classic model for cooperative behaviour among species in which cleaner fish or shrimps remove parasites and/or dead tissue from clients that pose at stations to solicit services from them (Cote 2000). Sharks, including pelagic thresher sharks, host a variety of ectoparasites that may affect their health and fitness (Oliver et ...

First record of the pelagic thresher shark Alopias pelagicus (Pisces: Alopiiformes: Alopiidae) from the Lakshadweep Sea, India [PDF]

Marine Biodiversity Records, 2012
The pelagic thresher shark Alopias pelagicus is a large, wide-ranging Indo-Pacific Ocean pelagic shark. In this paper, the first record of the pelagic thresher shark, caught from the Lakshadweep Sea is reported. The shark 275 cm in total length was caught by drift longline operation at depth of 60 m in the Lakshadweep Sea (10°52N latitude 72°13E ...

The Species and Origin of Shark Fins in Taiwan's Fishing Ports, Markets, and Customs Detention: A DNA Barcoding Analysis.

PLoS ONE, 2016
The increasing consumption of shark products, along with the shark's fishing vulnerabilities, has led to the decrease in certain shark populations. In this study we used a DNA barcoding method to identify the species of shark landings at fishing ports ...

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,

Vulnerability of oceanic sharks as pelagic longline bycatch

Global Ecology and Conservation, 2014
Bycatch (the unintentional catch of non-target species or sizes) is consistently ranked as one of the greatest threats to marine fish populations; yet species-specific rates of bycatch survival are rarely considered in risk assessments. Regulations often
