Yeah, we drift egg sacks on the Salmon river up here when they start to run. Flourescent green and pink seem to get the job done.
I used to clean Salmon on the weekends for the "gentlemen" that wouldn't. They paid $7 per fish and I kept the eggs to sell to the bait shops. They'd mix them with some dye, harden them with alum and make a tremendous profit.
I never tried for Steelhead because it interferes with deer season, but it looks like a good time if you can deal with the cold.
Sometimes I wake up grumpy. Other times I let her sleep.
