Evidence of silver eels contamination by microcystin-LR at the onset of their seaward migration: what consequences for their breeding potential?

International audience Thirty migrating silver eels Anguilla anguilla were collected in a river system where algal blooms occurred yearly. Fifty per cent of eel livers were contaminated by microcystin-LR (mean +/- S.D. toxin level: 28.1 +/- 22.4 ng g(-1)). Contaminated silver (v. healthy) eels had l...

Description
Summary:International audience Thirty migrating silver eels Anguilla anguilla were collected in a river system where algal blooms occurred yearly. Fifty per cent of eel livers were contaminated by microcystin-LR (mean +/- S.D. toxin level: 28.1 +/- 22.4 ng g(-1)). Contaminated silver (v. healthy) eels had lower fish condition. Consequences of this impact for the breeding potential of these migrating eels are discussed
