When the conditions are right, Rooks will troll from one weedline to another looking for dolphin. "Not all the weedlines have life under them," says Rooks. "Look in the water around the grass for anything living." Sometimes, he'll check eight or ten weedlines before he finds one that is alive with bait. When he spots a school of peanuts swimming in the grass, he tries to keep his boat running with the fish as they move down the weedline. "It's kind of tricky," he says. "But you have to keep the boat moving while letting the bait sink like it's not attached to anything." To accomplish this, he bumps the boat along the line in time with the moving school of fish while his anglers cast out chunks of bait and let them sink below the grass. Once he's had his fun with the bailers, Rooks will go looking for the gaffers. "To find bigger fish, move to deeper water and look for anything floating," he says. By the way, "anything" means exactly that: a log, a two-by-four, palettes or coconuts-whatever floats. Once Rooks locates a dolphin magnet, he'll first make a couple wide circles with his trolling spread. "Big dolphin aren't always tight to the structure," Rooks says. "Sometimes they're 50 yards away." Often, the biggest dolphin will come charging out of the cover followed by the schoolies.
