Read more than you want to and by the way that will not be enough ask a lot of questions of everyone you meet in LFS which mean local fish store. some stores have knowledgeable people but others do not you have to find out which ones have the people with the most knowledge. You are in luck Edmonton has many stores with good people at least from when I lived there. So I would ask questions on the forums there are many out there not all are Canadian but they have info also that will help.
