Station 1: About Crabs

The animal most people associate with the Chesapeake Bay is the blue crab. Blue crabs are well suited to the ever-changing salinity of the estuary, and can tolerate water ranging from salt to nearly fresh.

Because of their abundance and popularity as a food, people have been able to make their living from catching crabs. One of methods the students will use, the collapsible hand trap, is a popular method used by many crabbers. People also catch crabs using just a line and bait. Students will also try this method.
