Anchovy fishing in an area of Peru's North Central zone waters has been suspended indefinitely as part of an effort to protect stocks.

Vessels will not be permitted to fish within 30 miles of the coastline in waters spanning 622 miles (1002 km) between Trujillo on the northwest coast to Nazca in the south for the duration of the suspension.

The ban was reimposed on Dec. 31 after being in force for 10 days.

It will remain in force until scientists at Peru's Imarpe marine institute are satisfied there is no threat to the juvenile population.
