The sockeye or “reds” as the locals call them were in full swing when I was there. You can see the run numbers right on the Alaska fish+game website, and this year had quite a bit more fish show up.
You likely were not fishing for sockeye with eggs or any type of lures as they don’t eat like other salmon…their diet consists solely of zooplankton. The technique to catch them is to floss across the lanes they run in, which takes some practice. It’s mostly done from shore in water that’s about knee deep. The limit was 3/day in July, and we would limit out within an hour or so once we got the technique figured out.
In August is when the Coho start to show up in numbers in the Kenai, and people will fish for those from boats using standard salmon bait and lures.
