Asian shore crab: Change over time
This video analyzes Asian shore crab populations in Maine from 2002 to 2012.
It is divided into two separate sections: one part that analyzes the Vital Signs "Found" observations and then another part that analyzes the Vital Signs "Not Found" observations. Only "ID Confirmed" observations have been used in the making of this video. The video was inspired by the Variable watermilfoil change over time video posted earlier on the Vital Signs website.
