Eel migration report provides insights but also highlights data gaps
The International Council for the Exploration of the Sea (ICES) recently published its response to a European Commission request for advice on the seasonal migration patterns of European eel[1]. The paper contains an interesting summary of the knowledge that we have on migration patterns of European eel across the continent, including glass eel recruitment and silver eel escapement, but does not actually provide much advice on whether the current measures are having an effect or not, referring to data limitations and complexities.
