Tiny crustacean, big transformation: Part 2

The Monterey Bay Aquarium is working to make the global shrimp supply chain more environmentally sustainable, from family farms in Southeast Asia to customers’ plates in the United States. In this second installment of a four-part series, we take a peek at life on the shrimp pond—as Seafood Watch wades into the business of small-scale aquaculture in Southeast Asia. (Continued from Part 1.)


Pokkrong Kirdsook, Taylor Voorhees and Tyler Isaac walk single-file onto a thin wooden plank. The boards bow with each step, sagging closer to the pond four feet below. Pokkrong pulls up a spindly rope, lifting a cylindrical mesh cage from the water.

It looks like they could be panning for gold, but the riches in this cage are more lively. Exposed to the warm air on this humid afternoon in southern Thailand, whiteleg shrimp wriggle and jump on the mesh.

Taylor and Tyler, both Seafood Watch senior aquaculture scientists, admire the results. Shrimp farmers need to navigate a number of risks to produce shrimp this healthy. Even the variation within a lunar cycle can impact the development of their protective exoskeletons. 

The tiny pier on Pokkrong’s farm is 8,300 miles from the Seafood Watch office in Monterey, California, but Taylor and Tyler feel at home. Both worked in aquaculture production before joining the Aquarium; they even built a small aquaponic rig in Tyler’s backyard.

They’re visiting shrimp operations in the Thai province of Krabi to talk with farmers about everything from local government regulations to wastewater management and natural remedies for shrimp ailments. 

Across the Pacific, a powerful network of North American retailers—including Seafood Watch partners Blue Apron, Red Lobster and Whole Foods—are interested in what they find out. Read more…

Tiny crustacean, big transformation: Part 1

The Monterey Bay Aquarium is working to make the global shrimp supply chain more environmentally sustainable, from family farms in Southeast Asia to customers’ plates in the United States. In this first installment of a four-part series, we examine the growing American appetite for shrimp—and how it’s created a booming industry across the Pacific.


Every night, in kitchens across America, hundreds of thousands of people prepare the same dinner. Recently it was cavatelli pasta with zucchini, garlic and cherry tomatoes, sautéed in butter with mascarpone cheese and tender shrimp.

The portioned ingredients—down to the optional bottle of Viognier white wine—are delivered to customers’ doorsteps from Blue Apron, a national meal kit company that makes this sophisticated meal easy to prepare. The shrimp is also sustainable: As a partner of the Monterey Bay Aquarium Seafood Watch program, Blue Apron avoids seafood that’s produced in ways that harm other marine life or the environment.

Carrie Conley of Fort Irwin, California, says she chose Blue Apron because of its partnership with Seafood Watch. Sustainable seafood has been important to her since she started visiting the Aquarium, where she learned about the environmental impacts of fishing and aquaculture

“If I’m actively trying to find organic chicken,” she reasoned, “why not make better choices across the board?” 

Blue Apron makes it easy for customers like Carrie to access sustainably harvested shrimp. But producing that shrimp, and getting it into meal-kit boxes from faraway places like Southeast Asia, is anything but simple.

This is the story of how a broad network—including global seafood businesses, government agencies, Vietnamese shrimp farmers, U.S. chefs and the Monterey Bay Aquarium—are working together to make it happen. Read more…

Chefs serve up support for sustainable U.S. seafood

On June 14, chefs nationwide will be serving up support for our U.S. sustainable seafood law.

Over 50 culinary leaders across the country in cities like Honolulu, Los Angeles, Denver, Kansas City, Cleveland, Sarasota and New York are joining together that evening to celebrate the successes of the Magnuson-Stevens Act (MSA), our country’s premier fisheries management law—and to defend it from threats in Washington D.C.

Two bills currently before Congress, H.R. 200 and S. 1520, would weaken the MSA’s sustainability measures that have largely ended overfishing and recovered depleted species in U.S. waters. Chefs have been particularly vocal in their opposition to these proposals, pointing out that fisheries management is not just an issue for fisherman or coastal residents—it’s a food issue.

The culinary community from landlocked states knows this better than most. Seventy-two chefs from Midwest and Mountain West states recently weighed in with a letter to Congress, urging them to maintain science-based management and accountability measures of the MSA.

“Fisheries management may seem like a weird topic for chefs to get involved in,” says Danielle Leoni, chef and owner of The Breadfruit & Rum Bar in Phoenix, Arizona. “But we all love fish. And as a businessperson, I want access to a consistent supply of sustainable seafood—even though my restaurant is hundreds of miles from the nearest coast.”

Historic moment: Nations act to save Pacific bluefin tuna

Today in Busan, South Korea, Pacific nations came together and agreed, for the first time, to recover the population of Pacific bluefin tuna to a sustainable level.

“This is a historic moment for this remarkable species, which is so important to the ocean ecosystem and to coastal communities around the Pacific Rim,” said Margaret Spring, Chief Conservation Officer for the Monterey Bay Aquarium.

At the annual meeting of the Northern Committee of the Western and Central Pacific Fisheries Commission—the body responsible for managing tunas and other highly migratory species across the western Pacific Ocean—international delegates discussed ways to recover the population of Pacific bluefin tuna after years of decline. Ultimately, they took a major step forward by agreeing to recover the population to a sustainable level and establishing a long-term management plan.

Chefs worldwide speak out to save Pacific bluefin tuna

Leading chefs on five continents have pledged to keep Pacific bluefin tuna off their menus until there’s effective international action to manage the fishery and reverse a precipitous decline in the population.

Chef Alex Atala of Brazil: “We are not living within our means when it comes to Pacific bluefin tuna.”

Nearly 200 prominent chefs and culinary leaders from around the world—including Alex Atala of Brazil, James Beard Award nominee Michael Cimarusti of the United States and Annabel Langbein of New Zealand—say Pacific Rim nations must act immediately to recover Pacific bluefin tuna.

Bluefin tunas are among the planet’s most iconic and prized fish. In recent decades, global demand for Pacific bluefin tuna has driven the population down to a critical level—just 2.6 percent of its historic abundance, significantly lower than those of the two other bluefin tuna species, Atlantic and Southern bluefin tunas, and lower than all other assessed tuna species.

The chef pledge comes as fishing nations charged with securing the future of Pacific bluefin tuna prepare to meet in Busan, South Korea from August 28 to September 1, to craft a new recovery plan in the face of growing international criticism that the current plan falls far short of what’s needed.
