Honestly, I am not sure many people here monitor the gram to gram amount they take. They minimize foods high in omega-6s, and supplement with omega-3s. That's really the best option without getting unrealistic.
I recommend much higher doses of EPA/DHA, at-least 2 grams (I take 4-5) a day. That means the MG EPA/DHA in the supplement should add up to at-least 2 grams in the amount you would take in a day. And if you really want to get extreme (It's not necessary at all), males should take ones higher in DHA because of their lower bodily amounts/ higher risk for heart disease.
Your ratio will even out, not to mention you're doing much better then CW because even though PB is higher in fat, it's also much higher in saturated fats and monounsaturated versus polyunsaturated which dominates CW (and that's where OMEGA 6/3 Lay).
As far as salmon goes, I don't really eat sea food besides the occasional dinner outing because most of it is so toxic and contaminated nowadays. There's no point in eating salmon for omega-3s if you're getting a hefty dose of inflammatory chemicals and additives with it.
If you're going to eat salmon, I really do recommend you get a high quality organic type.
