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

Journal 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.

Occurrence of multiple congenital anomalies in Potamotrygon amandae (Elasmobranchii, Potamotrygoninae) embryos, including the first report of bicephaly

Journal of Fish Biology, EarlyView.

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

Journal 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).

Elasmobranch Bycatch in the Canadian Northwest Atlantic and Arctic Adjacent Seas: Composition, Biogeography, and Mitigation

, 2015
BACKGROUND: Industrial fishing has profoundly changed the biological state of oceans and seas. While the direct impacts of overfishing on target stocks are being increasingly addressed, unwanted bycatch and discarding of non-target species remains a key ...

Fish welfare in a changing world: New developments and current challenges

Journal of Fish Biology, EarlyView.
Abstract The welfare of non‐human animals is central to ethical discussions on animal use, with increasing attention to fish welfare across research, aquaria, aquaculture, and fisheries. This paper reviews current theoretical approaches to animal welfare and recent advances in defining and assessing fish welfare since the seminal paper by Huntingford ...

Late Cretaceous elasmobranch palaeoecology in NW Europe

, 2013
Late Cretaceous elasmobranch faunas are known from numerous of NW Europe localities but their palaeoecological characteristics are still poorly known. Recent studies on Anglo-Paris Basin elasmobranch faunas from phosphatic chalks provided detailed data ...
