Length–Weight and Condition Factor of 14 Elasmobranch Species Caught as Bycatch by Artisanal Shrimp Trawls in a Coastal Lagoon System From Northwest Mexico

Journal of Applied Ichthyology, Volume 2026, Issue 1, 2026.
The lack of biometric data on chondrichthyan species has impeded the implementation of management strategies essential for the conservation of sharks and rays captured using different fishing gears in coastal ecosystems. This study aims to assess morphometric relationships (length–weight [LW], length–dorsal length [DL], and length–disc width [DW]) and ...

Anthropogenic Factors Drive the Depletion of Fish Functional Β Diversity Within and Outside Two National Reserves in the Peruvian Amazon

Aquatic Conservation: Marine and Freshwater Ecosystems, Volume 35, Issue 12, December 2025.
ABSTRACT Understanding the impact of human activities on fish communities is critical for the effective conservation of Amazonian ecosystems. In this study, we sampled environmental DNA (eDNA) from 17 sites (lakes and rivers) in two Peruvian national reserves, Pacaya‐Samiria and Allpahuayo‐Mishana, using a metabarcoding approach with four genetic ...

Novel Use of Environmental DNA Metabarcoding to Assess the Impacts of a Large‐Scale Seismic Survey on Tropical Fish Communities

Environmental DNA, Volume 7, Issue 5, September–October 2025.
eDNA was used to assess whether there had been any impacts to an offshore demersal fish community. No major changes due to the seismic experiment were observed. When used in concert with baited remote underwater camera stations (BRUVS), a more comprehensive assessment of the fish community was obtained.
