AB  - The European eel is critically endangered. Although the quality of silver eels is 
      essential for their reproduction, little is known about the effects of multiple 
      contaminants on the spawning migration and the European eel management plan does 
      not take this into account. To address this knowledge gap, we sampled 482 silver 
      eels from 12 catchments across Europe and developed methods to assess three 
      aspects of eel quality: muscular lipid content (N = 169 eels), infection with 
      Anguillicola crassus (N = 482), and contamination by persistent organic 
      pollutants (POPs, N = 169) and trace elements (TEs, N = 75). We developed a 
      standardized eel quality risks index (EQR) using these aspects for the subsample 
      of 75 female eels. Among 169 eels, 33% seem to have enough muscular lipids 
      content to reach the Sargasso Sea to reproduce. Among 482 silver eels, 93% were 
      infected by A. crassus at least once during their lifetime. All contaminants were 
      above the limit of quantification, except the 
      1,2-bis(2,4,6-tribromophenoxy)ethane (BTBPE), Ag and V. The contamination by POPs 
      was heterogeneous between catchments while TEs were relatively homogeneous, 
      suggesting a multi-scale adaptation of management plans. The EQR revealed that 
      eels from Warwickshire were most impacted by brominated flame-retardants and 
      agricultural contaminants, those from Scheldt were most impacted by agricultural 
      and construction activities, PCBs, coal burning, and land use, while Fremur eels 
      were best characterized by lower lipid contents and high parasitic and BTBPE 
      levels. There was a positive correlation between EQR and a human footprint index 
      highlighting the capacity of silver eels for biomonitoring human activities and 
      the potential impact on the suitability of the aquatic environment for eel 
      population health. EQR therefore represents a step forward in the standardization 
      and mapping of eel quality risks, which will help identify priorities and 
      strategies for restocking freshwater ecosystems.
