Stochastic variation in G. salaris infections on Atlantic salmon. a-b. Residuals from the time-dependent model for infections using large inocula (Akerselva 2, Loneelva, Imsa). c-d. Residuals from the time-dependent model for infections using small inocula (Numedalslågen, Akerselva 3, Loneelva single worm, Neva single worm). (a) and (c) residuals plotted against age of infection, (b) and (d) plotted against ln population size
