Only half of Great Lakes residents are aware of advisories for safely eating fish
|
The study in the journal “Science of the Total Environment” found that five million people exceeded the recommended fish intake of two meals or 12 ounces per week, as suggested by the Environmental Protection Agency. Notably, women, nonwhites, younger residents and those with lower education levels were less aware of fish advisories, and thus more prone to eat more than the recommended amount.

Water test: One fish, two fish – where are all the whitefish?
|
Since the early 2000s fewer young whitefish have been making it to adulthood.

How the shape of the Great Lakes now compares with their past is important as negotiators update the consent decree addressing commercial and recreational fishing interests in waters covered by an 1836 treaty. The deadline is at the end of June, the third such decree covering these contentious waters. The most recent one in 2000 was for 20 years, and it’s overdue for an update.

April: Hidden Migrations
|
Animal migrations are among nature’s most stirring spectacles. So why do so few of us know about spectacular migrations that happen every spring, right in our own back yards? Because these are migrations of fish, out of sight beneath the surfaces of our rivers and streams.
