Thanks for the advice, folks. Just got back from a few days up there. Fished the backside of Malcolm Island one day mid last week (took the ferry - no way was I going to paddle from Cluxewe). There were lots of boats fishing and a fair number of pinks showing. I managed to get a pink while trolling, but no coho or springs. Other boats seemed to be getting pinks and not much else.
Fished in front of Cluxewe, trolling mostly. No pinks were showing until Friday, when I had to leave. I didn't get so much as a bite.
Also fished around Port Hardy and had my best luck. Launched at Storeys Beach with the intent of trying for halibut behind Shell Island or near the airport. Instead, I found myself in a huge, thick bait ball just on the south side of Shell Island. I only had my halibut setup (stupid!), but I happened to have a Lil Nib jig, so I threw that on and jigged. Hooked up multiple times with what were certainly springs. Had an amazing spring on, awesome fight - lasted at least 10 minutes - lots of jumps, rolls and head shakes. Had it to the boat, under the boat, around the boat... finally had it close enough to land and it shook the hook. The fish won that one and deserved it. Anyway, it was a blast. Good trip.
