The boundaries of the Juan De Fuca canyon are loaded with marine life from mammals to baitfish spring-fall along with everything in between. Bearing witness to some "blue-planet-like" stuff out there has been one of the highlights of my experiences on the big blue. The canyon itself is heavily trafficked by large processors/trawlers (midwater hake/pollock mostly, but some bottom dragging does happen). Longliners do the blackcod-sablefish/halibut thing as well. The boundaries of the JDF canyon are a favorite for commercial salmon trollers for good reason.

For recs that don't mind the boat ride/fuel consumption, adult chinook fishing can be ridiculous July/Aug. A good percentage of columbia-bound adult chinook feed out there and get large inside of 100 fathoms. Even fraser-bound whites make up some of the percentage of chinook caught in the vicinity of the canyon. Albacore seem to be at times numerous approaching the 500 fathom line too. Often the whale show is worth the price of admission June-Sept.
