Beware the Fatty Sushis
Otabenga,
You can get the same amount or more of omega-3s from fish that are lower on the food chain and/or not farmed, and thus much safer for you to eat because they'll be lower in mercury and other toxins, as well as being better environmental choices -- mackerels and sardines are good examples of very good omega-3 fish, which are also very tasty when properly prepared.
The fish flesh doesn't have to be full of fat for you to get the omega-3s. Indeed, there are big problems with the whole agenda promoting the consumption of fish for omega-3s. Farmed salmon, for starters, often don't even contain anywhere near the amount of those healthful fatty acids that wild salmon would, and that the fish-farming industry would have you believe, partly because more and more the farmed fish are being fed with vegetable-oil based feed. And in eating enough toro to get omega-3s, you're exposing yourself to such a high mercury risk that it's not worth it.
It makes much more sense, I would suggest, not to choose the seafood you eat in order to get a supposed supply of omega-3s, and instead just to take omega-3 tablets manufactured from relatively sustainable stocks of fish like mackerel, sardines, and anchovies, which are low on the food chain -- these supplements are also filtered to remove any toxins as well. That is what I do.
And I find I don't really miss the salmon and toro at the sushi bar, because I've come to find the fattiness of those fish too cloying, and I now prefer the more interesting and subtle tastes and textures of other, leaner fish.
