| Impact Description | European eels (Anguilla anguilla) that inhabited freshwaters had significantly lower muscle fat contents and more serious infections than eels that never entered freshwaters. Since low Anguillicola crassus infection intensities and high fat contents are necessary for successful transoceanic spawning migration, which might impair reproductive success. |
