According to a report the Walleye and other sport fish contain more mercury that one could imagine. These fishes are found in the Great Lakes region and in certain parts of Michigan. However, their presence could be dangerous for consumers of these species.
Scientist studied the toxin in these sport fish as it could have harmful effects on pregnant women and children’s brain development. One of the officers in charge of the study said that Michigan has been under a mercury fish advisory for years and they are still not sure that the coming report will give an exact feedback about the level of mercury. It’s an alarming situation for fish consumers as they will have to abstain themselves. There is still an inheritance of toxin which persists even if an evaluation has shown a 20 % decline in emission, said the Tuesday report.
The mercury in fish is still a great threat for the inhabitants of this region and its surroundings. Scientists said that despite the fall in emission, the mercury continues to be present in some species and this is a major issue for humans and the wildlife. The study clearly showed that the concentrations of mercury in some fishes are very high. Over the past four decades, especially in lakes and rivers the toxin level is quite high. After 3years of study, in a report was released by the Great Lakes Commission, it was said that the fish was uneatable due to the high level of toxin. It includes the northern pike, walleyes, lake trout and the large-mouth bass. The analysis also shows that the level of contamination depends on the place the species were caught.
