The state Department of Natural Resources is working on improved fishing guides and hunting digests for 2013.

But first, they’re asking for public input in an effort to make the guides more useful.

So if you’ve ever struggled to understand or make sense of a fishing or hunting guide from the DNR, here’s your chance to speak up.

Feedback is being gathered over the next several months from focus groups and surveys, according to Michigan United Conservation Clubs.

The surveys must be completed by Feb. 3.

The results will help identify discussion topics for focus groups to be held in late February and March.

For more information, see the Hunting and Trapping Digest survey, and the Fishing Guide survey.

This E. Coli Attaches to Your Intestines

Central Michigan University researchers have found mysterious genes in the sands of Great Lakes beaches.

The genes are from disease-causing E. coli bacteria, which can make people sick and lead to beach closings.

E. coli is a common indicator bacteria used by health departments to test beach waters.

But here’s something more uncommon: The E. coli pathogens found at seven beaches contained genes that can attach to a person’s intestinal wall and secrete toxins.

Those were found in sand at public beaches along Lake St. Clair, and Lake Huron. Researchers speculate that the bacteria could be using these “attachment genes” to survive in the sand.

The scientists say more study is needed to assess the health implications of these findings.
