Welcome aboard SJ,
....coupla great questions there and I hope it sparks a bit of a discussion because it’s such a worthy and timely topic!
1) Should you wait ‘till you see bait:
This is totally dependent upon where you’re fishing. Since Friday 2/16 is that Marine Area 8&9 winter opener, let’s start there. On Possession Bar, a high-probability hotspot, Get your gear down and EXPECT to find bait and chinook. I would take this approach on Pt. No Point, Double Bluff and Midchannel Bank as well.
Inside areas such as south Hat, Camano Head and Langley can be “metered” or looked at with your fishfinder very quickly without deploying the cannonballs and I generally will not fish unless I’m marking bait in these sandy areas of reduced current flow.
On the other hand, if I have jigging or mooching in the back of my mind, I’m looking for opportunities to make a vertical presentation the whole time I’m trolling.
In the San Juans where rocky structure is more the rule rather than the exception, I’ll generally meter an area before committing in an effort to rule out unproductive areas. With the vast amount of fishing areas in A7 you have the luxury of being choosy while in A9 there’s simply less to choose from.
2) How long do you stay? I let the tides and currents make that call for me. If I’m marking chinook and bait while approaching a tide change, it’s time to stick and stay and make it pay. On the other hand, if it’s past tide change and marks are sparse?
Time to run and gun!
Great questions and keep ‘em comin’!
