Catching a mahi mahi [dolphin fish or dorado] off the coast in Washington state isn’t a usual catch, but it’s not unheard of. In El Nino years when warm water pushes north, mahi, marlin, swordfish and other warm-water pelagic species will follow the albacore tuna sometimes as close as 30 miles to shore.
What is unusual is when those fish get big. Ask Wade La Fontaine, from Camano Island, Washington. On August 25th he was 42 miles offshore fishing with Far Corners Adventures Sportfishing when he hooked into a 21 lb. new state record Mahi Mahi. The previous Washington state record mahi weighed 16.27 lbs and was caught by Albert DaSilva out of Ilwaco in 2013. The fish was a total suprise and would be considered a trophy catch anywhere in the world.
The water temperature that far out was 70 degrees, prime for all sorts of exotic species to show up in an albacore bite. Far Corners Adventures is running tuna trips just about every day the weather cooperates. You can find them at https://watuna.com/ or by calling 253-606-5754.
