After doing some searching I did find some info. from the Indiana DNR.DNR: FAQs along with a link to this website.
The Snakes of Indiana

"Like many other states, Indiana is making an effort to protect its reptiles and amphibians (herpetofauna). Thus the collection and possession of herpetofauna in the state requires a hunting or fishing license for all persons 17 years or older (unless you are collecting on your own farm). Bag limits and seasons are in place to regulate the number of reptiles and amphibians collected each year. Typically, in the case of animals such as snakes, the limit is four. These regulations were established due to the drastic declines in populations of snakes and other herpetofauna throughout the state. Without protection, these species would continue to decline. Endangered species may not be collected or possessed without special permits. There are additional requirements for dangerous species, or for having extra animals for breeding or conducting research. If you have any questions regarding the collection of snakes and other reptiles and amphibians, contact the Indiana Department of Natural Resources, Division of Fish and Wildlife at (317) 232-4080 or your local Conservation Officer."
