Michigan's animals of concern list is being updated to include the mudpuppy, Fowler's toad, pickerel frog, Butler's garter snake, and smooth green snake.

The Michigan Natural Resources Commission says it is now illegal to kill or trap those animals or remove them from the wild.

The commission also approved several changes to state fishing regulations dealing with commercial bait and bow and spear fishing.

One of the revisions sets rules for taking minnows, wigglers and crayfish for commercial purposes and lists waters closed to personal taking of minnows.
