If you opt for canned salmon, I recommend looking for wild Alaskan salmon. My favorite brand of canned salmon is Wild Planet and it's sustainably caught in Alaskan waters. As for how much, there’s one pound of salmon in the recipe (which is 16 ounces), and most cans are 6 ounces, so you’ll need three cans. Note: Canned Salmon can be dryer than using fresh salmon. You may want to double the amount of mayonnaise to 1/4 cup to keep your salmon patties nice and moist.
