"Vast Marine Protected Area 'Boosts Tuna Stocks'"

"A huge marine reserve in the Pacific Ocean has led to the recovery of tuna and other migratory fish around its borders, according to a study.

The Papahānaumokuākea Marine National Monument in Hawaii is almost four times the size of California.

Fishing is banned inside the zone, but a spillover effect has boosted tuna stocks in nearby waters, scientists have found."
