Heard reports about Bluefish around Plum Island and Merrimack River. Covered a lot of water trolling and all that was caught was Mackerel. I didn't see any surface activity and with Macks still around, I figured the Blues moved off. Didn't focus on Stripers yesterday.
Curious what were you trolling that you caught mackerel on... anything I can think of that would be appropriate for catching bluefish would be way too big for mackerel.
