Snapper, Mutton – US 
Mutton Snapper are most commonly found in the tropical waters of the Caribbean, Florida and Gulf of Mexico. They can live to 40 years of age, have moderate growth rates, and become sexually mature after three years.
Mutton Snapper were overfished for many years, but their abundance has increased and today it is at a medium level in the South Atlantic US and Gulf of Mexico.
Mutton Snapper are mostly caught by hook-and-line, bottom longlines or traps, fishing methods which cause moderate habitat damage and some bycatch of sea turtles and sawfish.
