The mud shrimp affects organic structure, nutrients, and the grain size of sediments in mudflats. Some of this activity creates difficulties for oyster growers, causing the application of pesticides in oyster growing areas in the 1950s. It may be that the changes in the ecosystem caused by introduced oysters and pesticides opened the doors for subsequent invasions. In 1999, a parasitic isopod was discovered to be infecting the native mud shrimp, and effectively sterilizing the shrimp. A related species, the Asian mud shrimp. Upogebia major, is less susceptible to the parasite, and has begun to fill in spaces formerly occupied by the blue mud shrimp. While this article is concerned with mud shrimp populations in California, the dynamics discussed are relevant to Oregon estuaries. If the ways our estuaries are engineered changes thanks to the double invasion, the way we manage our estuaries will also have to change.
