Obviously any food if consumed in vast quantities could cause your calorie intake to exceed your expenditure, resulting in weight gain. However as a low fat low carb high protein food you really would have to go some to get fat only on salmon. It would in fact be quite a good choice for the basis of a high protein low carb diet.
Any source of calories, if consumed enough, can cause weight gain, but in general, fish oils are quite good for you and since fish has such a small amount of fats (relative to beef), it's an excellent source of protein for any weight loss program. So the answer is, "no, if you eat normal portion sizes."

Some will gain weight, and others will lose it. Drugs have different effects on different people, and can either make you feel more hungry (gain weight) or less hungry (lose weight).
