Conceptual model of “foraging-based” dilution: (A) graphical representation of the interaction between U. crassus density and glochidia load on the two dominant fish species; (B) at high mussel densities, large quantities of glochidia are released over a limited water surface, P. phoxinus consumes them in the water column, while remaining larvae settle and might be intercepted by G. gobio; (C) at low mussel densities, fewer glochidia are intercepted in the water column, forcing P. phoxinus to forage on the bottom, where it competes with the better-adapted G. gobio.
