If it was caught near Talkeetna it was probably a King Salmon (aka Chinook to those of you in the Pacific NW). Indeed there are salmon connoisseurs. Kings are very good, but many people consider Reds the best. Silver Salmon (aka Coho) are also excellent. We also have Pink Salmon (ak Humpies) which are mostly canned, but are also tasty if cooked right after they are caught.

They all differ somewhat in flavor, oiliness, color of the meat, etc.
