Heleobia piscium (d'Orbigny), Chilina fluminea (Maton), and Gundlachia concentrica (d'Orbigny). After the introduction of the invading bivalve, the presence of Ch. fluminea and G. concentrica is accidental.
Another example of the impact on the local mollusk fauna is the settling of the golden mussel on native bivalves (naiads) and on another invading bivalve, Corbicula fluminea.
This kind of impact on benthic fauna is similar to that caused
by Dreissena polymorpha on native bivalves in the Northern
Hemisphere.
Another kind of
impact is observed at Guaíba Basin (Brazil), where the golden mussel
prevents the normal development of marsh plants like rushes.
The presence of the golden mussel also alters the trophic chains of
the environment. For instance, the "boga" (Leporinus obtusidens)
in the Río de la Plata changed its diet opting for the golden mussel
as its main food.
