“Limits” on seafood are more suggestions about reducing exposure to ocean borne toxins. But some fish have much less incidence of toxins, and there isn’t any other Eason to limit exposure.
Salmon are pretty clean, especially Canadian and Alaskan harvests. As @Tropical_Willie pointed out, albacore should be limited, along with other tuna. And be careful about farmed Chilean sea bass and tilapia, some of those are raised in foul circumstances.
There are a lot of web sites that tell you what seafoods to avoid, such as the Monterey Bay Aquarium.
