In general, a good rule of thumb when it comes to mercury content is to consider the size of the fish. Smaller fish such as salmon, scallops, sardines and shrimp contain less mercury than their larger predators such as bigeye tuna and swordfish. (This information is from Livestrong.com)
Fish to avoid:
- Bigeye tuna
