Fast response of freshwater consumers to a new trophic resource: Predation on the recently introduced Asian bivalve Limnoperna fortunei in the lower Paraná river, South America
Comparison of Limnoperna fortunei numbers and biomass in screened (5, 15 and 40 mm) and unscreened cages deployed for 18 months in the lower Paraná delta indicates that predators harvest 26-79% (numbers), or 20-85% (biomass) of the mussel population. Predation impact decreases with mussel size. On a...
