For a correct assessment of eel in the Sudoe area, data collection and assessment methods need to be standardised and thus comparable. In SUDOANG, we have coordinated with the managers to collect all the scattered information about:

• Eel abundance
• Distribution and biometric characteristics of the eel
• The impact of ecological discontinuities on the eel

In this document we present the conceptual and physical model of the database we have developed to host the information.
