Researchers are studying whether Great Lakes fish contaminated by mercury are threatened more by low oxygen in the water than healthy fish.
The International Joint Commission recently recognized runaway plant growth, a cause of low oxygen, as a major Great Lakes problem. The U.S./Canadian commission advises those governments on Great Lakes issues.
Low oxygen is called hypoxia, a condition the U.S. Geological Survey says is caused by an increase in nutrients. Nutrients and other contaminants often enter lakes and streams by way of surface runoff. Fertilizer, …

Fish with characteristics of both genders are more prevalent than previously thought in U.S. rivers, according to a recent U.S. Geological Survey study.
While this study did not analyze fish in the Great Lakes, it may raise new concerns as to whether previously noted hermaphrodite fish in this region are becoming more prevalent as well.
“Until we take current sampling it is hard to know,” said Chris Metcalf, director of the Institute for Watershed Science at Trent University in Ontario. “However, all studies are symptomatic of …

Editors note: This is part of a series about issues relevant to the biennial meeting of the International Joint Commission.
Over the summer of 2008 environmental groups and Great Lakes shippers were on the edge of their seats. Congress was working on water quality standards to prevent invasive species from entering the lakes from the dumping of untreated ballast water on freighters.

Editors note: This is part of a series relevant to the International Joint commission’s biennial meeting in Windsor on Wednesday and Thursday.
More than 20,000 beaches closed last year when water samples tested positive for harmful bacteria.
But inconsistent sampling methods have Great Lakes officials questioning those results.
The International Joint Commission, a binational organization that advises the U.S. and Canada on Great Lakes issues, examined problems with beach testing methods and advisory systems in a report released last month.
It is among the issues to be discussed …

LANSING – The bobcat hunting and trapping season in Michigan’s Upper Peninsula will start three months later because of an apparent drop in the bobcat population.
The UP season will be shortened from four months and a week to two months. The start date for the trapping season, originally Oct. 25, is now Dec. 1, and the hunting season now begins on New Year’s Day.
The Department of Natural Resources opted to shorten the season rather than reduce the bag limit from two to one bobcat, …
