Atlantis Canyon is one of the reliable shelf-edge canyons for the southern New England and Cape fleets, cutting into the continental slope where warm water and bait concentrate the pelagics. It holds the full canyon slate, yellowfin, bigeye, marlin, swordfish and mahi.
The canyon
Fish the edge, tips and fingers of the canyon, keying on the temperature breaks and bait. Its position on the shelf edge makes it a common overnight target when the good water is in the neighborhood.
How to fish it
Troll by day, chunk overnight in a slick, deep-drop for swordfish, and work floating structure for mahi.
Tip Atlantis and its neighbors fish on the water, so compare the canyons before you commit. The warm blue edge might be dialed in on Atlantis one week and on Veatch or Block the next, so run to the temperature, not the name.
