>> He's in the water!>> Sports fishermen are taking the plunge, in search of one of the most expensive and sought after fish in the Pacific Ocean, the bluefin tuna. 19 year old Ryder DeVough is capitalizing on a resurgence of the fish, not seen off the coast of California for decades.
Reuters photographer, Mike Blake.>> This is a prize fish for them to head out to catch. And it's a very hard fish to catch as well, it's a smart fish. As it gets bigger, it gets smarter.>> Usually, these tuna I've had to dive anywhere from shallow of the surface up to 55, 60 feet.
>> The bluefin tuna are making a come back after over fishing, spurred by a growing global appetite for sushi lead to a population decline. Now global conservation efforts are being credited for returning the species to the waters of California.>> Scientist at the National Oceanic and Atmospheric Administration say quotas placed on the over fish bluefin back in 2011, are starting to make a difference.
There is a 6,600 metric ton limit for this fish over the span of two years, for both Mexico and the United States combined.>> The quota included commercial fishermen and people like DeVough.>> Port's Fisherman had a quota on the fish, it used to be ten fish per person per day, and they scaled that way back to two fish per person per day.
>> One scientist Reuters spoke to said they're seeing more and larger bluefin tuna off the coast of California.>> And the challenge of catching them is paying off. Large bluefin tuna can sell for hundreds of thousands of dollars each.
