Abstract: Musculista senhousia (Benson in Cantor, 1842) is a soft sediment-dwelling
mussel that has spread anthropogenically from its native Asia to North
America, Australasia, and Europe. This byssal mat-forming species can become
overwhelmingly dominant and have dramatic impacts within invaded ecosystems,
but its invasion may meet "ecological resistance" from native predators. In
Mission Bay, San Diego, California, three fish species and two shorebirds were
found to prey upon the mussel. Experimental results suggest that predation can
dramatically impact intertidal mussel populations and may account for observed
seasonal declines in the species. Despite the creation of a byssal cocoon, which
may afford the mussel some protection, several taxa worldwide have been found
to be Musculista predators. In addition, in areas where the mussel is native,
humans impact mussel populations by gathering it for animal feed or bait, or to
remove it from commercial shellfisheries grounds.
