Although sockeye (reds) don't bite much, they can be caught. And yes, alot of people "line 'em". I won't question or get into the sporting issues with lining, all I know is that once you hook 'em, pound for pound they're the wildest salmon I've had on the end of the line. I did '01 & '02 on the Kenai in July. Here is a link that has plenty of patterns to review. I used several of the ones identified here. Oh, and by the way... reds are a FOOD FISH !!!
