Fish Need to Move! Learning About Fish Migration - American shad

Since colonial days we have been prized for our meat and roe, or eggs. By the late 1800s, we were one of the most commercially valued fish on the east coast. Today, our populations are dramatically reduced.

Overfishing, pollution, and not being able to reach our spawning habitat because of dams and other barriers, caused our decline. Fishing for us is not allowed in many states, or the number people can catch is limited.
