A new Maine law limits the use of some lead fishing gear in an effort to protect the state's loon population.
The bill went into law without the governor's signature on Thursday.
The sale and use of lead sinkers an ounce or less will be prohibited beginning this fall. The sale of so-called bare lead-headed jigs two-and-a-half inches or shorter will be prohibited in September of 2016, and their use a year later.
The state says lead poisoning from lures and sinkers is the leading cause of death for Maine's adult loons.
The bill is sponsored by Democratic Sen. Anne Haskell of Portland. She says the new law will help preserve loons for future generations.
