Tracking Fin‐Prints on Reef Flats: A Genus‐Specific eDNA Metabarcoding Assay for Epaulette Sharks (Hemiscyllium spp.) With Field Validation in Raja Ampat

open access: yesEnvironmental DNA, Volume 8, Issue 3, May–June 2026.
This study developed and validated the first genus‐specific eDNA assay for epaulette sharks (Hemiscyllium spp.), targeting the NADH4 gene. Field application in Raja Ampat detected H. freycineti at six of seven locations, including one location (Dayan) where daytime visual surveys failed, demonstrating this tool's value for monitoring protected species.

Trypanorhynch Assemblages Indicate Ecological and Phylogenetical Attributes of Their Elasmobranch Final Hosts [PDF]

open access: yes, 2017
This study explores non-metric multidimensional scaling (nMDS) as a tool for investigating parasites as indicators of the elasmobranch biology. An attractive feature of nMDS is its ability to allow assemblage-level parasite data to be simultaneously ...

Insights into the structure of grey reef shark aggregation, Carcharhinus amblyrhynchos (Bleeker, 1856), in two distinct channels of the Maldivian archipelago, Indian Ocean

open access: yesJournal of Fish Biology, Volume 108, Issue 4, Page 1347-1360, April 2026.
Abstract The grey reef shark Carcharhinus amblyrhynchos is one of the most frequently encountered reef‐associated shark species in the Maldives, yet very little is known about its local size structure or population dynamics. This study provides new insights into two aggregations of C.

Drone-Based High-Resolution Tracking of Aquatic Vertebrates

open access: yesDrones, 2018
Determining the small-scale movement patterns of marine vertebrates usually requires invasive active acoustic tagging or in-water monitoring, with the inherent behavioural impacts of those techniques.

Fishery of elasmobranchs with some observations on the biology and stock assessment of Carcharhinus limbatus (P. Muller & Henle, 1839) exploited along Malabar coast [PDF]

open access: yes, 2012
Elasmobranchs are caught in trawls, gillnets and longlines along the Malabar region of Kerala and they are landed almost round the year, accounting less than 1% of the total catch.

Optimizing a Novel eDNA‐Based Framework for Reef Fish Biodiversity Monitoring Using an Autonomous Filtration System and in situ Nanopore Sequencing

open access: yesEcology and Evolution, Volume 16, Issue 3, March 2026.
This study presents a comprehensive eDNA metabarcoding protocol optimized for monitoring fish biodiversity in coral reefs and other remote marine environments. By combining an autonomous underwater filtration system, Oxford Nanopore sequencing, and a 12S reference database specifically developed for French Polynesia, the method enables efficient and ...
