I geuss that no fish is smart but i do find that salmon steelhead and carp spook a lot easier than bass do, making them seem smarter. They also seem to learn quicker than bass. I have had some bass bite, get hooked and landed on the same bait multiple times, however when i hook a salmon or steelhead on a lure or a fly and they get off they purposely avoid that fly or lure i hooked them on
