The spread of the invasive parasite has dramatically depleted mud shrimp populations along the northwestern coast of North America. "All previously known abundant Upogebia populations were either absent or at greatly reduced abundances in all California, Oregon and Washington estuaries examined." (p.1225) "[U]rgent, immediate responses, including captive breeding programs for the most impacted Upogebia populations and species are warranted." (p.1234) ER -
