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.

Reproductive behaviour of the ocean triggerfish Canthidermis sufflamen (Tetraodontiformes: Balistidae) in the shallow waters of the marine‐protected area of El Hierro Island (Canary Islands)

open access: yesJournal of Fish Biology, EarlyView.
Abstract The abundance of Canthidermis sufflamen has increased worldwide, including around the Canary Islands, due to global ocean warming. The reproductive behaviour of this species was studied within a marine‐protected area (MPA) and its adjacent areas off the island of El Hierro (Canary Islands).

Beyond spring season: An autumn observation of adult lumpsuckers (Cyclopterus lumpus) in coastal Norway Frøya archipelago raises questions on extended spawning activity

open access: yesJournal of Fish Biology, EarlyView.
Abstract During snorkelling near Frøya, central Norway, on 6 October 2025, a pair of adult lumpsuckers (Cyclopterus lumpus) was observed engaged in apparent prespawning behaviour in shallow kelp habitat. Such activity is surprising, as the species is mainly considered a spring spawner throughout the eastern Atlantic and is the focus of a targeted ...

First record of young‐of‐the‐year smooth hammerhead (Sphyrna zygaena) in coastal waters of Galicia, northwest Spain

open access: yesJournal of Fish Biology, EarlyView.
Abstract The smooth hammerhead (Sphyrna zygaena) is typically considered an oceanic species and is only rarely observed in the cooler coastal waters of the northeastern Atlantic. On 20 December 2024, a juvenile S. zyganea was captured at 25 m depth in the inner Ría de Pontevedra (Rías Baixas, northwest Spain).
