What's Eating My Spot

Type: Chesapeake
Region: Southern
Location: Thomas Point Light

Was fishing at Thomas Point on the 4th and when I reeled in one of my spot rods I found this half eaten spot, I was wondering if this was the work of a bluefish or something else? I haven't caught or seen any blues in around Thomas Point this year.

Daniel, bluefish are beginning to make their way up the bay so be ready for them.
