Finding: The mighty 4-inch crayfish can be bold or shy
|
Experiments at the U-M Biological Station in Pellston show how exposure to the popular herbicide atrazine can affect whether crayfish are bold or shy, and thus their ability to protect themselves from predators like large-mouth bass. Atrazine gets in rivers, lakes, groundwater and agricultural run-off. Tested crayfish came from Cheboygan County.
