Overall, consumers should be aware of the sourcing and preparation of fish to ensure low mercury levels. Many fish species have variable mercury levels based on their habitat and diet, making informed choices essential for health and environmental reasons.
Why Is Mercury a Concern in Maine Saltwater Fish?
Mercury is a concern in Maine saltwater fish primarily due to the potential health risks it poses to humans when consumed. Mercury accumulates in fish tissue, and higher levels of mercury can lead to serious health issues for individuals who eat contaminated fish.
The U.S. Environmental Protection Agency (EPA) defines mercury as a toxic heavy metal that can have harmful effects on human health. Specifically, the EPA states that methylmercury, a form of mercury that easily accumulates in fish, is of particular concern due to its toxicity.
Several factors contribute to mercury contamination in Maine saltwater fish. First, mercury is released into the environment from various sources, including industrial emissions and the burning of fossil fuels. Second, atmospheric mercury can settle on water bodies, where it is transformed into methylmercury by bacteria. Third, fish absorb this toxic compound from water and their diet, leading to biomagnification—where mercury concentrations increase as one moves up the food chain. Larger predatory fish tend to have higher mercury levels than smaller species.
Methylmercury is a concern because it can adversely affect the nervous system. It impacts brain development, especially in children, leading to cognitive deficits. Additionally, high levels of mercury can cause neurological problems and cardiovascular issues in adults.
Specific conditions that exacerbate mercury contamination in Maine include increased industrial activity and the subsequent release of mercury into the atmosphere. For example, historical gold and silver mining operations contributed to higher mercury levels in certain environments. Seasonal factors, such as water temperature and fish spawning cycles, can also influence mercury concentrations in fish populations.
In summary, mercury in Maine saltwater fish is a concern due to its health risks, environmental sources, and its ability to accumulate in fish tissue. Public health advisories recommend monitoring and limiting the consumption of certain species known to have higher mercury levels to protect consumers.

-
Species selection: Certain fish species are generally recognized for having lower mercury levels. Based on data from the Environmental Protection Agency (EPA), the following species are safer choices:
– Haddock
– Pollock
– Mackerel (Atlantic)
– Hake
These species tend to accumulate less mercury compared to larger predatory fish. -
Size and age: The size and age of a fish significantly influence its mercury concentration. Younger fish tend to have lower mercury levels compared to older, larger fish. For instance, studies show that a fish’s mercury level increases as it ages, due to bioaccumulation. Therefore, opting for smaller individual fish will generally yield safer choices.
-
Local guidelines: It is crucial to review any local health advisories regarding fish consumption. The Maine Department of Marine Resources provides updated information about mercury levels in local fish. They often publish guidelines indicating which species are safe to eat and recommended serving sizes. This information helps anglers make informed choices regarding their catch.
-
Catch and release practices: If you do catch larger predator fish, consider practicing catch and release. By returning these fish to the water, you help sustain fish populations and reduce the risk of consuming mercury-heavy species.
In summary, being aware of species, considering size and age, adhering to local guidelines, and practicing responsible fishing can help you effectively identify low mercury saltwater fish when fishing in Maine.

These recommendations reflect a balance between the nutritional benefits of fish and the risks associated with mercury exposure.
-
Choosing Low Mercury Fish:
Choosing low mercury fish involves selecting species that are known to have lower mercury levels. Health officials advocate for consuming varieties like flounder, haddock, and salmon. According to the U.S. Environmental Protection Agency (EPA), these fish are safer choices and can provide essential nutrients such as omega-3 fatty acids, which are beneficial for heart health. The Maine Department of Marine Resources supports this guidance in its educational resources for consumers. -
Limiting or Avoiding High Mercury Fish:
Limiting or avoiding high mercury fish is essential for reducing exposure to this toxic element. Species like swordfish, shark, and king mackerel typically contain higher levels of mercury due to their position in the food chain and longer life spans. The Maine Public Health Guidelines recommend avoiding these fish, especially for pregnant women, nursing mothers, and young children, who are more vulnerable to mercury’s harmful effects. -
Local Advisories:
Local advisories regarding fish caught in specific waters must be consulted to ensure safety. Maine officials provide updated information on mercury levels in local fish species based on testing results. Consumers are encouraged to visit the Maine Department of Environmental Protection’s website or contact local fish markets for the latest advisory information. -
Consideration of Age and Health Status:
Considering age and health status is crucial when determining how much fish to consume. Young children, pregnant women, and nursing mothers should adhere to more restrictive guidelines due to the potential for mercury to impact fetal brain development and childhood cognitive function. The Agency for Toxic Substances and Disease Registry (ATSDR) emphasizes the need for these groups to be particularly mindful of their fish consumption choices. -
Awareness of Contaminants:
Awareness of potential contaminants in fish, including polychlorinated biphenyls (PCBs), is also important. PCBs were banned in the United States but persist in the environment and can accumulate in fish tissues. Health officials recommend checking local fish advisories for specific guidance on PCB levels. The Maine Department of Health and Human Services offers resources to help consumers navigate these concerns.
Together, these recommendations aim to promote the consumption of fish while safeguarding public health against the risks of mercury and other contaminants.
