Fish, such as salmon, contains long chain omega-3s, but unfortunately now is often contaminated with mercury and other toxic pollutants, so long chain omega-3s may be more safely obtained from plant-based supplements (see also here).

And only grilled chicken beats out grilled salmon for certain carcinogenic contamination. Fish, including salmon, has often been found to be contaminated in fecal bacteria above what the national guidelines permit.
