It's only a few dollars for the trout stamp, so not a big deal, but you're probably a little late for catching them from shore. You could still use a kayak or small john boat and catch them fairly close to shore, but the likelihood of catching a king or coho from shore now is lower. You're much more likely to catch steelhead close to shore right now.
Spring is when you'll have the best luck fishing the harbors and breakwalls for salmon. At least that's when I've had my best luck.
