The effect of foraging and ontogeny on the prevalence and intensity of the invasive parasite Anguillicola crassus in the European eel Anguilla anguilla
Abstract Infection patterns of the invasive Anguillicola crassus nematode were investigated in a population of the European eel Anguilla anguilla where parasite invasion is very recent , Loch Lomond, Scotland. Intensity levels of the parasite were associated with differences in fish ontogeny and tro...
