Small fish like sardines are a safe choice, but there are non-swimming sources of essential fatty acids out there too.  Find omega-3s in flax seed oil, black current oil, walnuts and walnut oils, dark leafy vegetables, eggs (preferably from free range chickens), spices (including mustard, fennel, cumin, and fenugreek).  Get your omega-6s from evening primrose, borage and black currant oils.
