Lydonia Canyon is another of the rich Georges Bank canyons along the southern edge of the bank, near Gilbert and Oceanographer. It holds yellowfin, bigeye, bluefin, marlin, swordfish and mahi when the water is right.
The canyon
Fish the edge and the fingers along the bank. Like the rest of the Georges chain, it is a long run best fished as part of a well-planned overnight or multi-day trip.
How to fish it
Troll the edge, chunk overnight, deep-drop for swords, and cast to mahi on the floating structure.
Tip On the Georges canyons, watch the whole eastern edge on the charts. The best break can shift from Lydonia to Gilbert to Welker week to week, so let the temperature and bait pick the exact canyon.
Canyon-run safety The canyons are a long run into deep, open ocean, usually an overnight or multi-day trip far beyond help. Go in a capable, well-found boat, watch the weather window closely, carry proper safety and communications gear (EPIRB, life raft, redundant electronics), and file a float plan. This is serious offshore fishing.
Regulations Tuna are federally managed highly migratory species requiring an HMS permit, with category, size and retention rules that change through the season. Confirm current rules with NOAA Fisheries HMS before fishing.
