Five of the most commonly eaten fish that are low in mercury are shrimp, canned light tuna, salmon, pollock, and catfish. They found that mercury levels averaged 45 ppb (parts per billion) in canned salmon and 55 ppb in mackerel, compared with as much as 340 ppb in tuna in oil. When it is fired for electricity generation, the mercury is released as smoke into the atmosphere. These fishes are a popular delicacy but their biomass is very low in reservoirs compared to other cichlids.
