| Summary: | A survey started in 2016 and is conducted every year in early autumn (September to early october) to quantify the abundance of european eel in the Bresle, Normandy. The electrofishing protocol of eel abundance indices (2022) is used. It targets juveniles of european eels, but older fish are also caught and included in this dataset. Sampling is restricted to areas with shallow running water. The data consist of abundance indices and biological traits measured on the fish sampled: length, weight. The survey is carried out under the Research Observatory on Diadromes Fishes in Coastal Streamss (ERO DiaPFC) program. The data are stored in the database of the ERO. They are used to develop predictive models and tools for providing scientific advice to improve the management of this species. ... |
