Back in the day when no limit to size of sturgeon or amount I would stub only when trolling for strippers. I would stay berth at every harbor for one year to recon style and location of the areas. Richman red rock marina, Pt. san Pablo, Rodeo, echlys, c&h sugar, antiock, mare island, mothball, Petaluma/montazuma, & cotata, etc. etc. Did you know you could catch grass shrimp with a beef bone meated? Netted gunny ,sack, 15" ring( like a ring crab net) will get you 6 or more shrimp. just OFF the side of the boat on the bottom while waiting for that dino bite.
