Fish are regularly contaminated with PCBs and other pollutants, with bioaccumulation and biomagnification providing significant doses; this includes heavy metals.
Or you could skip the downsides and get those nuts and seeds and other plants with omega-3 fatty acids… or just algae based supplements (algae are the origin of the nutrient for those fish).
Nuts and seeds have way too many Omega 6 fatty acids, wich counteract Omega 3 and can cause heart problems
A vegan keto diet is hardly possible because of that
Omega 3 (ALA, a predecessor of EPA and DHA which you also need) comes from few plants in high concentrations: flax (linseed), hemp, chia
Additionally, microalgae oil for direct EPA and DHA can help, as the transformation of ALA in the body only fulfills the basic needs

You are right, but nuts and seeds are also more expensive.
