This is what the regulation book says:
"Littering of any materials, including parts of fish or other animals, and depositing rubbish, poisonous substances, or chemicals harmful to aquatic life into public waters, onto ice, or lake or stream shores is illegal. “Chumming” (depositing fish parts >>or other material <<into public waters to attract fish) is unlawful. Fish line and various packaging materials can be harmful to wildlife".
I went to their office last summer and they showed me the section where it says "or other material" .So the answer to me was anything you throughout like you would when chumming is not allowed.
Would like to stop back there and ask about other ways and if its legal or not.
I hear it's best to get these kinds of things in writing in case I get checked on the bank somewhere
