Integrative taxonomy reveals four new species of the armoured catfish genus Pareiorhina (Siluriformes: Loricariidae) from the upper Paraná River basin, Brazil

open access: yesJournal of Fish Biology, EarlyView.
Abstract Four new species of the small‐sized armoured catfish genus Pareiorhina are described from mountain ranges in the Grande River drainage, upper Paraná River basin, based on morphological and molecular species delimitation methods. Molecular analyses based on the cytochrome oxidase subunit I (COI) marker recovered Pareiorhina as polyphyletic ...

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

Assessment of two minimally invasive methodologies for sex identification in the European eel, Anguilla anguilla

open access: yesJournal of Fish Biology, EarlyView.
Abstract Sex is an important driver of variation in behaviour, ecology and physiology. Sex identification in the Critically Endangered European eel (Anguilla anguilla) currently requires fish sacrifice, or the use of morphological differences such as body length, which can be inaccurate in certain habitats and at intermediate body lengths.

Fatal Hemorrhagic Septicemia in Common Guitarfish (Rhinobatos rhinobatos) Caused by Photobacterium damselae Subsp. damselae in a Controlled Environment

open access: yesJournal of Fish Diseases, EarlyView.
ABSTRACT Elasmobranchs, including sharks and rays, are commonly housed in public aquariums due to their ecological significance and educational value. The common guitarfish (Rhinobatos rhinobatos), currently listed as ‘Critically Endangered’ by the IUCN, is particularly susceptible to population declines due to overfishing and bycatch.
