Striped bass will migrate up and down the East Coast as water temperatures warm up in the spring. The peak run will be dictated by water temperatures and bait fish. As the water temperatures warm and bait fish move into certain areas, the striped bass will follow. In April, you will usually see plenty of fish move into the Maryland area and over the next month and a half or so, you will see strong numbers of fish move all the way up the U.S. east coast.
