We have not crabbed this late in the year but our results earlier in the fall (mid-October) and in late spring (mid-May) would indicate that the high water flows push the crabs out of the Slaw pretty good. I would be waiting for a drop in the water flow and then, based on conditions being safe, I would drop a pot or 2 in the deep water near shore just W of the CG, another out mid-channel by CG, and then I would get some pots all the way down by A6 buoy and perhaps A4.
As for seals, we have never had much of an issue with them getting into box traps or better pots in the Slaw, we use salmon heads often, tuna scraps, kokanee heads, and sometimes chicken soaked in Pautzkees Crab/Shrimp Fuel.
Good luck if you get out, hope you find some... cheers, roger
