Predictive habitat suitability models to aid conservation of elasmobranch diversity in the central Mediterranean Sea. [PDF]
Sci Rep, 2015 Commercial fisheries have dramatically impacted elasmobranch populations worldwide. With high capture and bycatch rates, the abundance of many species is rapidly declining and around a quarter of the world’s sharks and rays are threatened with extinction.

Gills, growth and activity across fishes
Fish and Fisheries, Volume 24, Issue 5, Page 730-743, September 2023., 2023 Abstract Life history theory suggests that maximum size and growth evolve to maximize fitness. In contrast, the Gill Oxygen Limitation Theory (GOLT) suggests that growth and maximum size in fishes and other aquatic, water‐breathing organisms is constrained by the body mass‐scaling of gill surface area.

Journal of Applied Ichthyology, Volume 2023, Issue 1, 2023., 2023 In this study, we report, for the first time, mitochondrial genome of Narcine timlei (Bloch & Schneider, 1801) and its phylogenetic relationships within the order Torpediniformes. Narcine timlei is a medium‐sized ray that occurs in nearshore waters of the Indo‐Pacific and is classified as “‘vulnerable” category on the IUCN Red List.

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.

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 ...
