Density-dependent effects of Anguillicola crassus larval infections in the copepod intermediate host were examined experimentally. Three species of copepods (Cyclops vicinus, C. viridis and C. fuscus) were subjected to a range of doses of larval A. crassus within infection arenas. Prevalence, intensity and parasite dispersion (variance: mean abundance)(More)
Density-dependent effects on adult and larval stages of the introduced nematode parasite Anguillicola crassus in the European eel definitive host were examined in the laboratory in naturally infected fish, and in field samples. The effect of adult nematode subpopulations on larval development over time and the effect of increasing adult intensity on the(More)
