The European eel was classified as critically endangered by the International Union for Conservation of Nature (IUCN) after multiple factors – including habitat loss, overfishing, oceanic changes and an increase pollutant and pathogen levels – had collectively contributed to the decline of the species. Scientists and administrations from nine countries (Albania, Algeria, Egypt, France, Greece, […]
One of the reasons why European eel population has not recovered despite the Recovery Plan put in place by the EU in 2007 is the lack of common dialogue and strategies among the stakeholders involved (administrations, scientists, managers, the fishing industry, NGOs) and at different levels (local, regional, national). In an attempt to overcome this […]
One of the main goals of SUDOANG is to have common tools and methods that contribute to the conservation of the European eel and its habitat in the SUDOE zone (Spain, France and Portugal). In an attempt to stardardize age reading of eel otholiths, scientists from SUDOANG and from the Working Group on Eels (WGEEL) […]
Although most of the planned face-to-face events had to be cancelled due to the COVID, SUDOANG joined the worldwide celebration of obstacle-free rivers through a letter to the eel.
In Sudoang we present the results of the EDA model (Eel Density Analysis) to our associated partners which gives the abundance of silver eel in rivers. It is important that stakeholders involved in eel management and conservation validate the results obtained by the models to detect inconsistencies. In this video we briefly explain how the […]
With the collaboration of all our partners and associates, we are finishing one of our main products: the eel distribution atlas. During this time, the characteristics of the habitat of the species and the obstacles blocking its passage have been collected and will soon be available in this atlas. In addition, all this information has […]
European eel is critically endangered (IUCN 2014): glass eels entering European rivers are 10% of those that arrived before the 80s. A team of scientists, fishers, managers and NGOs worried by the eel situation decided to use knowledge to bring the eels back to our rivers. That’s how Sudoang was born.
The GEREM (Glass Eel Recruitment Estimation Model) model is an analytical tool developed to estimate recruitment at different spatial scales. In this report we show how the GEREM model has been applied to the SUDOE area to obtain an estimation of recruitment at three spatial scales: SUDOE scale, subarea/region scale and basin scale, and we […]
Eel management in the SUDOE area is fragmented into several administrative units: basin, region and country. Furthermore, the commercial exploitation of this stock and its habitat (mainly for hydroelectric power use) affects many stakeholders whose interests need to be reconciled. For this reason, dialogue between them is fundamental, as we explain in the following video […]
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 […]
