Join radio host Boyd Matson every week for adventure, conservation and green science. This week his guests try to solve the mystery of the disappearance of Michael Rockefeller, figure out if Mother Nature is really trying to kill you, ski off the seven summits including Everest, look inside the city of Damascus during the Syrian War, dive into Mission Blue with Sylvia Earle, look at how much food we waste each year, take a walk on the surface of Mars, and find out what we should pack on a camping trip.

March 24, 2014: Big Wave Crashes, Haitian Folk-Tunes, Babysitting Gorillas and More

Join radio host Boyd Matson every week for adventure, conservation and green science. This week they are held underwater until they blackout and are rescued, put Langston Hughes’ poetry to music, study bats in the living room, grow up with gorillas, survive a deadly Antarctic expedition, remind travelers to represent their nations, refuse to order bluefin tuna sushi, and create stronger laws to protect elephants.

Electronic Tagging and Tracking Marine Animals Supports Conservation

Understanding and predicting animal movement is important as it is central to establishing effective management and conservation strategies [1]. Until relatively recently, studying the movements and behaviors of highly migratory marine species (turtles, sharks, whales, penguins, seals and billfish) have been challenging due to the logistical and technological constraints of working in aquatic environments. However,…

2013: Making Strides toward Sustainable Tuna

By Susan Jackson and Holly Koehler Across the globe, as populations soar, a growing number of people are relying on seafood for their nutrition and their livelihood. Tuna is one of the most popular species of seafood, and the industry surrounding it is an economic engine for countless communities. With competing interests at play, and…

Geography in the News: Bluefin Tuna Decline

By Neal Lineback and Mandy Lineback Gritzner, Geography in the NewsTM Bluefin Tuna in Decline The Convention on International Trade in Endangered Species (CITES), an international agreement between governments, dealt a serious blow to the Atlantic bluefin tuna in March 2010. The convention voted to deny a proposed international ban on fishing and trading the…

From Crown to Cage: The Changing Face of the Tuna Trap Fishery in Sardgena

For the last month, I have been immersed in a world of traditional bluefin tuna traps in three small towns in the Southwest corner of Sardegna (Sardinia): Carloforte, Portoscuso, and Porto Paglia. In each of these towns you cannot go far without seeing or hearing some sort of reference to bluefin tuna.  Whether it is…

A sustainable tuna fishery? Traditional trap fishers in Sardegna say yes.

Some people’s parents pass on to their children a love for skiing, some a love for cooking, my father passed along to me a love for tuna.  By love for tuna, I don’t mean a love for eating spicy tuna rolls or a love that makes me anti-fishing, it more is the kind of love…

The Bottom Line: Coming Together for Bluefin Tuna

It’s not every day that fishermen and environmentalists agree. But in a significant move, the American Bluefin Tuna Association and the International Game Fish Association are partnering with The Pew Charitable Trusts to protect bluefin tuna, one of the most amazing fish in the sea. By working together, we might be able to help ensure…

Insanity Caused By Eating Bluefin Tuna

Recently, the owner of several sushi restaurants in Japan paid nearly $1.8 million U.S. dollars for a single bluefin tuna.  Last year this same individual paid what was then a record price—about $ 740,000. With this year’s fish the man outdid—not to say outbid—himself. But presumably other bidders were pushing the price into orbit before…

The Bottom Line: Bluefin Tuna Need You Now

In the Gulf of Mexico, surface longlines intended to catch yellowfin tuna and swordfish indiscriminately catch and kill more than 80 other species of ocean wildlife, including severely depleted western Atlantic bluefin tuna. This species is particularly at risk: Scientific studies have identified it as a distinct population (as compared to eastern Atlantic bluefin) that reproduces…

The Bottom Line: A Short Season for Big Fish

This year’s purse-seine fishing for bluefin tuna in the Mediterranean Sea kicked off this week, but don’t blink or you might miss it. On Tuesday, May 15, large commercial purse-seine vessels with massive nets set out to catch literally tons of tuna by encircling entire schools of breeding bluefin. The season officially ends June 15,…

Keeping Fishermen on the Line

As the US presidential election cycle heats up, I’m always fascinated and a bit frustrated by how complex issues needing real solutions get dumbed down into slogans. I guess I shouldn’t be surprised given the success of twitter. People love simplistic one-liner solutions. Curiously, in the world of tuna there is a long history of…

The Bottom Line: Tracking Tuna in the Cloud

Several months ago, I wrote about a study showing that Atlantic bluefin tuna were being caught at a rate much higher than scientists recommended and regulations allowed. Furthermore, fishermen were not reporting their catches to the International Commission for the Conservation of Atlantic Tunas (ICCAT), the body that manages tuna in the Atlantic Ocean. This underreporting undermines measures designed…

Happy New Year Bluefin!

A North Pacific Bluefin tuna fetched 56.49m yen/$736,000 at Tsukiji fish market’s first tuna auction of the year.  Bluefin stocks in the Atlantic and South Pacific are depleted to fractions of their original size thanks to overfishing driven primarily by the Japanese sushi market.  Many of us, who may love sushi as much as the…

Overfishing 101: Counting Fish

Read the full “Overfishing 101″ series here. How heavy is 35,000 metric tons? For starters, it’s the weight of 193 jumbo jets or 2,917 African elephants. It’s also the amount of Atlantic bluefin tuna that have exceeded the official catch quota in the Mediterranean Sea in the past two years alone, according to a Pew-commissioned analysis…
