Abstract or Summary
  • Carcinus maenas is an invasive marine predator. Its generalist feeding strategies make it one of the most effective invaders. Carcinus maenas has invasive populations throughout the world, and was recently introduced to the west coast of North America. This study looks at the abundance and growth of C. maenas in Yaquina Bay, Oregon following the 2014-15 El Niño. We explore the spatial and vertical distribution of C. maenas and how it relates to the distribution and abundance of the native Cancer productus. We did not find a correlation between the spatial distribution of C. productus and C. maenas. We discuss the possibility of the spatial distribution being related to the dynamics of the bay or microhabitat preference. Our data suggests a negative correlation in the vertical tidal distribution of the two species, and seems to support the hypothesis that C. productus sets the vertical lower limit of C. maenas. We made observations of the interactions of the two species in the same trap that also support this hypothesis. Lastly, we found an abundance and size distribution similar to that of the 1997-98 El Niño. Future studies should follow the 2015 year class and its effects on the local ecosystems. These data could prove a valuable tool in making predictions on the effects of El Niño or the establishment of a sustainable C. maenas population in Yaquina Bay.
