A Review of the Status of Sharks, Rays and Chimaeras of Panama to Guide Research and Conservation

Aquatic Conservation: Marine and Freshwater Ecosystems, Volume 35, Issue 4, April 2025.
ABSTRACT Chondrichthyan fishes (sharks, rays and chimaeras) are a group of high conservation concern globally. Species are impacted by varying threats, although fishing pressure is the primary stressor causing population declines. Panama comprises both Pacific and Caribbean coastlines with a diversity of estuarine and marine habitats supporting small ...

Mitigating the effect of by‐catch on endangered marine life

Animal Conservation, Volume 28, Issue 2, Page 172-184, April 2025.
Fishing gears cause substantial impacts on the oceans and their ecosystems, and many marine animals, such as sea turtles, marine mammals, seabirds and elasmobranchs, end up as by ‐catch. In this paper, the most effective mitigation measures were investigated for each group, taking into account the fishing gear with which they interact most.

Design and Validation of an Open–Close Device for Integrated Environmental DNA Sampling Detects A Depth Gradient in Indian Ocean Deep‐Sea Fish Assemblages

Ecology and Evolution, Volume 15, Issue 2, February 2025.
The goal of this study was to leverage existing survey technology to design and test an eDNA sampler that captures an integrated eDNA sample over the length of a deep‐water transect. We provide a biological interpretation of the resulting data, demonstrating the usefulness of such technology to understand the ocean environments, using fish species as ...

Feeding Ecology and Reproductive Biology of the Common Smooth-Hound Shark Mustelus mustelus (Linnaeus, 1758) off the Coast of Türkiye

Fishes
Sharks play critical roles in marine ecosystems as apex or mesopredators, regulating trophic dynamics and ecosystem stability. However, their populations are increasingly threatened due to overexploitation caused by targeted fisheries, bycatch, and ...

Can denticle morphology help identify southeastern Australian elasmobranchs?

Journal of Fish Biology, Volume 104, Issue 6, Page 1848-1859, June 2024.
Abstract Elasmobranchs are covered in scale‐like structures called dermal denticles, comprising dentine and enameloid. These structures vary across the body of an individual and between species, and are frequently shed and preserved in marine sediments.
