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.
