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