The European green crab, Carcinus maenas, is a generalist predator that has established invasive populations throughout the world, including the west coast of North America. In Oregon, strong cohorts of green crabs recruit only during major El Niño events. The goals of this study are to: 1) compare the abundance...
The European green crab (Carcinus maenas) has persisted in Oregon and Washington coastal estuaries since the late 1990s. A strong year class arrived during the 1998 El Niño, but numbers decreased and remained below 1 per trap per day until the arrival of the 2015-2016 El Niño. Since then, numbers...
European green crab, Carcinus maenas, trapped and collected in coastal Oregon and Washington coastal estuaries during the 2019. Data for individual crabs include: estuary, site, date of collection, sex, carapace width, weight, molt stage (color of abdomen), missing limbs, estimated year class, method of collection, and name of collector.

In Yaquina Bay, Oregon, I observed very little overlap in the distribution of the invasive green crab, Carcinus maenas, and the larger red rock crab, Cancer productus. Red rock crabs dominate the more saline, cooler lower estuary and green crabs, the less saline, warmer upper estuary. Because caged green crabs...
