A host-parasite model is proposed to describe the dynamics of the P. decipiens complex life-cycle. Four developmental stages are considered: the adult worm in the final host's stomach, the larval stages in the invertebrate and fish hosts, and the free-living egg-larval stage. The dynamics of each stage are described by an ordinary differential equation. The sensitivity of the model to some parameter values forms the basis for a discussion of its potential use in the assessment of future management and control strategies. This is illustrated by examples of observed infections in cod (Gadus morhua) from Scottish waters in the light of the recent increase in the Grey seal (Halichoerus grypus) populations of the Orkney and Farne Islands.
