After 80-year absence, bluefin tuna—world’s most-prized game fish—reappear off California Coast

SAN DIEGO (Reuters) - Large Pacific bluefin tuna not seen in California waters for decades have reappeared, to the delight of fishing enthusiasts and scientists, as global conservation efforts have proven effective for one of the ocean’s priciest and most sought-after fish.

Overfishing of bluefin tuna spurred by a growing global appetite for sushi resulted in a critical decline in stocks over decades. But measures by the United States, Japan, Mexico and others to limit their take have led to population growth, though tuna populations are still below historic levels.
