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.

Speciation of European bullheads (Cottus spp.): The next problem for taxonomy of northern freshwater fishes

open access: yesJournal of Fish Biology, EarlyView.
Abstract High morphological and ecological diversity displayed by European bullheads led Freyhof et al. (2005) to describe 15 nominal species. However, the basis for declaring these nominal species is contentious due to a lack of rigorous statistical analysis of morphological variations among populations, limitations in the inferences made from ...

Contrasting population genomic structuring of northern pike (Esox lucius L.) in fresh‐ and brackish water environments: Implications for management and conservation

open access: yesJournal of Fish Biology, EarlyView.
Abstract Understanding the factors that shape population genetic structure is crucial for advancing evolutionary studies and developing effective management and conservation strategies. The northern pike (Esox lucius L.) is a top teleost predator that inhabits fresh and brackish water environments in the northern hemisphere.
