The California Department of Toxic Substances Control is considering banning some types of metal fishing gear. However, fishermen are launching a petition against possible changes.
The California Sportfishing League is gathering signatures for a petition that would oppose changes in fishing tackle regulations.
There is concern about a possible ban on lead sinkers or gear that contains zinc or copper.
Marko Mlikotin with the League says there are no environmental studies showing fishing tackle poses an environmental hazard.
"Largely fisherman when they cast their lines, they pull their equipment out of the water so there really is no threat to the environment," says Mlikotin.
He says any change would be costly and would hurt tourism.
Meredith Williams who is Deputy Director of the Department of Toxic Substances Control says lead weights can be toxic if ingested by waterfowl.
She says the department will hear from manufacturers about possible alternatives and will talk to fishermen and the scientific community.
"And really make sure we understand the product and its use and the concerns from all sides before we make any decision."
Williams says a final decision could be three years away.
