Host density

WebApr 21, 2024 · Host density is a key regulatory factor in parasite transmission. The goldfish (Carassius auratus)-Gyrodactylus kobayashii model was used to investigate effects of host density on population growth of gyrodactylids.A donor fish infected by five gravid gyrodactylids was mixed with 11 parasite-free goldfish at five host densities. Webwith increasing host density, the breakpoint of this curve should be determined by the density of resident hosts rather than by the overall density of the hosts. Consequently, the flea burden should decrease with the proportion of resident individuals, under the same over-all abundance of the host and the same overall abun-dance of parasites.
