Age and growth of the endemic groovebelly stingray (Dasyatis hypostigma), a heavily exploited batoid in the Brazilian Meridional Margin (21–34° S)

open access: yesJournal of Fish Biology, EarlyView.
Abstract Life‐history data are often lacking for exploited elasmobranchs, jeopardizing proper management and conservation measures for this vulnerable group. Herein, we provided age and growth estimates for the groovebelly stingray (Dasyatis hypostigma), a medium‐sized, heavily exploited batoid endemic to the southwestern Atlantic Ocean.

Growth‐regulating proteins differ between British seawater fish species, shedding light on their ecological adaptations

open access: yesJournal of Fish Biology, EarlyView.
Abstract Wnt proteins are a family of molecules that help control how cells grow, develop and communicate – processes that are fundamental to the development and health of all animals. Although Wnt pathways have been studied extensively in model species, very little is known about how they operate in marine fish.

Pigmentation disorders in three specimens of spiny dogfish, Squalus acanthias Linnaeus, 1758, from the Gulf of Venice, northern Adriatic Sea

open access: yesJournal of Fish Biology, EarlyView.
Abstract This study reports three cases of pigmentation disorders in Squalus acanthias from the Gulf of Venice. Two specimens exhibited spotless phenotypes, whereas one exhibited hypermelanism. Morphological assessments were conducted for two individuals, alongside genetic analysis of mitochondrial genes to determine phylogeographic relationships. Both
