Period of the day drives distinctions in the taxonomic and functional structures of reef fish assemblages. [PDF]
J Fish BiolAbstract Circadian processes are key drivers of animal behaviour, influencing patterns of activity, resource partitioning and competition avoidance. Studies evaluating circadian changes on the structure of marine assemblages are lacking, especially for reef fish.

Memorias do Instituto Oswaldo Cruz, 1991 The presence of four Monogenoidea parasitic on marine fishes from the central Peruvian coast is recorded. One of them, Anoplocotyloides chorrillensis (Monocotylidae) described from the gills of Rhinobatos planiceps (Rhinobatidae) is considered a new ...

Conservation Letters, Volume 15, Issue 5, September/October 2022., 2022 Abstract One third of chondrichthyan species (sharks, rays, and chimeras) are threatened with extinction, mainly due to unsustainable fishing. Large accessible international markets for meat and luxury products like dried fins can help drive overfishing by encouraging targeted capture or retention of high‐value export species.

Spatially explicit risk assessment of marine megafauna vulnerability to Indian Ocean tuna fisheries
Fish and Fisheries, Volume 23, Issue 5, Page 1180-1201, September 2022., 2022 Abstract By‐catch is the most significant direct threat marine megafauna face at the global scale. However, the magnitude and spatial patterns of megafauna by‐catch are still poorly understood, especially in regions with very limited monitoring and expanding fisheries.

Conservation Science and Practice, Volume 4, Issue 7, July 2022., 2022 Abstract Increasing fishing pressure has negatively impacted elasmobranch populations globally. Despite high levels of historical and current fishing pressure, the Bay of Bengal region remains data‐poor. Focusing on Bangladesh, we conducted a socio‐ecological study to characterize elasmobranch fisheries and evaluate their impact on threatened species ...

Journal of Applied Ichthyology, Volume 38, Issue 4, Page 455-461, July 2022., 2022 Abstract The capture of a female specimen of the velvet belly lantern shark Etmopterus spinax with abnormal skin coloration is reported. The specimen was captured off northern Spain (Bay of Biscay, North‐eastern Atlantic) in 2021 by bottom trawling. The lack of dermal melanophores combined with a normal retinal pigmentation, lead us to considerate the ...

Ecomorphology of oral papillae and denticles of Zapteryx brevirostris (Chondrichthyes, Rhinobatidae) [PDF]
Zoomorphology, 2016 Elasmobranchs have an impressive range of highly specialized sensory systems shaped over 400 million years of evolution. The morphological analysis of oral papillae and denticle in elasmobranchs elucidates the biological role that these structures play during feeding and ventilation, bringing important descriptive information about ecological ...
