Visits the Chesapeake Bay from spring through autumn. Abundant in the lower Bay, but also common most years in the upper Bay as far north as Baltimore. In early autumn, they will migrate out of the Bay to spend the winter in warmer waters off the Florida coast.


The bluefish eats squid and small, schooling fish such as menhaden and anchovies. It uses its sharp teeth to attack and feed on prey. Possibly the most voracious predator in the Bay, a bluefish will kill another fish just for the sake of killing it.


Sharks, tuna and swordfish may prey upon bluefish. Humans catch bluefish for commercial and recreational purposes.

Reproduction and Life Cycle:

Spawning occurs off the mid-Atlantic coast during summer. Juveniles from this spawning period and a southern spring spawning period enter the Bay in late summer. Bluefish can live for more than 12 years.
