We fished Napa River this week and were able to land a sturgeon bait fishing using live grass shrimp. That's the only thing that seemed to work. We spent all morning trolling everywhere in the river and sloughs and had no bites. We then decided to anchor up on good marks and bait fishing using live grass shrimp and bullheads. The grass shrimp worked. I wish we did this from the beginning. We ended up bait fishing for about 1.5 hours in the afternoon and got our shaker sturgeon.
