In a study of sea louse parasites on chum salmon , we presented a host–parasite model that incorporates the effect of parasite-mediated predation on host populations. After publication of the original article, we discovered an error in the functional response of the host–parasite model that we wish to correct to prevent it from being repeated if the model is applied to other systems. The host–parasite model presented in equations (3.2) and (3.3) should be corrected to read such that the denominator of the multi-prey functional response includes the average capture rates on all individuals of species i and not just those with x parasites. This correction resulted in changes numerical simulations such that a higher prey abundance was required to observe the same behaviour reported in our original paper. Details are posted as a supplement to this correction.
We thank the Editor, Dr Hans Heesterbeek, and Associate Editor Dr Vincent Jansen for their constructive feedback on this correction.
