The bluefish diet is varied, but they pursue almost any forage fish, including butterfish, menhaden, herring, silversides, anchovies, shrimps, lobster, crabs and worms. They will hit almost any type of fly when on the feed, and color seems downright unimportant. Popovics' favorite way to fish blues is with poppers on the surface. His fly of choice is a Banger, but only when they are on top. He has taken monster blues on his Cotton Candy flies tied as large as 14 inches with 10/0 hooks. ''The big blues I was after had no trouble chasing it. In fact, it was the only fly I could move fast enough and keep upright at the same time. For giant blues, a fly that large is nothing,'' Popovics says.
