> Problem is--when I checked the lipid content of these fish I found a 100 gram (about 3.5 oz) serving had hardly any EPA (20:5 n-3) or DHA (22:6 n-3). I don't see how anyone could get more than a couple of grams, short of 3 squares a day of mackerel with a cod-liver oil chaser.

I'm using the USDA Nutrient Database (http://www.nal.usda.gov/fnic/cgi-bin/nut_search.pl).No, you're eating the right fish. My data shows that herring, sardines, and salmon each have over a gram of omega-3 per 100 grams of fish. One small can of salmon has two such servings.
Here are a couple links to tables derived from the USDA database, that make comparisons of fish lipid content easier:

http://www.cs.princeton.edu/~ah/food/data/fishshellfish.lipids3
Go to the main link (below) for access to tabular arrangements of the vitamin, mineral, lipid, and amino acid content of various meats and vegetables, and so on. Much easier to use than the USDA format, IMHO.
