BaitNH. The fleas weren't bad on the downrigger lines. I use 30# Ande. The problem was mostly on the wire Slide divers (regular dipseys not so bad) where they would collect at the connection between the wire and the mono leader.
Fished yesterday out of Fairhaven from 70 to 500 FOW from 0800 to 1600 . Only marked one probable Salmon and very few bait pods. Temp (53 degrees F) was initially at 75 feet, later 50 feet. Fished Dipsies, proven downrigger spoon programs, flashers and flies and cut bait all to no avail. Spiny water fleas were very bad on the dipsey rigs, had to clean them off every half hour to avoid clog-ups. Hope things improve soon.
Good Question Barn Dog,
This late I have had my best luck fishing deeper 100- 350 FOW for 2 year olds and steel head. You won't see many other boats but the fishing can be great. Good fishing!
