| the effect of foraging and ontogeny on the prevalence and intensity of the invasive parasite anguillicola crassus in the european eel anguilla anguilla. | 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 trophic ecology. although eels foraged on both fish and invertebrates, individuals which were smaller and fed on invertebrates (>70% contribution to diet) were found to contain a greater number of swim bladder par ... | 2017 | 28084623 |
