The French Polynesian Marine Resources Ministry has imposed a three-month ban on catching six species as part of a conservation effort.
The ban applies from November the 1st, with some species and some islands seeing curbs for up to half a year.
The restriction on some of the shell fish prohibits the catching, transporting and eating of the species.
The ministry says the ban, or rahui, is in line with traditional practices to keep the fisheries sustainable.
Those found to be violating the rahui can face jail terms of up to six months and/or fines of 3,500 US dollars
