CLF Aquaculture Links: January 2016

AQ-news-300The Dietary Guidelines for Americans (DGA) 2015 – 2020 were released last week and many public health and sustainable food system experts were dismayed over the exclusion of sustainability considerations. It appears politics played a large role in deciding not to include sustainability–which was in the report of the Dietary Guidelines Advisory Committee, which the DGA is based on. The specific guidelines for seafood look very similar to past dietary guidelines; Americans are advised to eat two servings per week, which would double current average consumption. Read the seafood related guidelines at the DGA website, CLF’s reaction to the DGA on our blog, and our public comment with suggestions on what to include in the DGA’s seafood recommendations, which we submitted in May while the guidelines were under development.

AQ-news-300GE salmon is the same as non-GE salmon? When genetically engineered (GE) Atlantic salmon was approved for human consumption by the FDA, consumer groups responded by clamoring for a new process that would review GE food animals and require the products be labeled as GE. But FDA has decided that GE salmon is equivalent to non-GE farmed Atlantic salmon. Read the article at the New York Times and FDA’s response to Read More >

AQ-news-300Climate change damages ocean ecosystems. Ocean acidification and temperature increases are wreaking havoc on plants and animals that live in the ocean, upending marine food webs, and hurting diversity and energy flows. According to the FAO, fisheries and aquaculture support the livelihood for 10 to 12 percent of the world’s population—the collapse of ocean ecosystems would deal a significant blow to global food security and the global economy.

CLF Aquaculture Links: September 2015

AQ-news-300Debate over open ocean fish farms. Open ocean finfish farming is being considered four miles off the coast of San Diego in the Pacific Ocean, and similar ideas are being discussed in the Great Lakes region. The proposed San Diego farm is a joint partnership between Hubbs-Sea World Research Institute and private investors, and would be the nation’s largest, raising yellowtail and sea bass. Presently, it is unclear whether the proposed farm will be permitted. The Great Lakes is new to net pen aquaculture, but Michigan State University and Michigan Sea Grant are testing the waters by hosting a public forum about the topic. Supporters and critics of both regions are lining up to debate the issue. Read the articles at NPR and Michigan State University Extension. Read More >

Highlights from Aquaculture America 2015

Female zebrafish

Last month, just a few days after Mardi Gras, hundreds of aquaculture farmers, business leaders, scientists and policymakers converged on New Orleans for the annual Aquaculture America conference. A wide range of fields were represented: food fish, baitfish, zebrafish for genetic research, shellfish, shrimp, and algae for food, fuel and feed. I delivered a talk titled “Public Health Perspectives on Aquaculture,” (abstract) which I presented in a Seafood and Health session. Here are some “notes from the road” highlighting what I found Read More >

2013 USDA Census of Aquaculture: Highlights

From the 2013 USDA Census of Aquaculture

From the 2013 USDA Census of Aquaculture

The USDA Census of Aquaculture is the most important and comprehensive data source for understanding the trajectory of the U.S. aquaculture industry. Last conducted in 2005, the census is a snapshot of production amounts, methods, and sales information from thousands of aquaculture operations in the United States.

The key finding from the census was an across-the-board decrease in the number of farms in the U.S. Roughly 3,000 farms responded to the 2013 census, which was a 28 percent decrease from 2005. The total acreage Read More >

Sea vegetables emerge on New England local food scene

Portland, Maine, 2014.

Portland, Maine, 2014.

The names “alaria,” “dulse,” “kelp,” and “laver” may not mean much now, but a growing cadre of aquatic farmers and chefs in New England are trying to change that. These types of edible seaweed (or sea vegetables) are revered by cooks for the jolt of salty goodness they bring to soups and salads, and by health food advocates who dig the high levels of minerals in seaweed.

These ocean-derived foods were on display last week at the Maine Seaweed Festival Read More >

USDA Organic standards for aquaculture under development

Will farmed fish qualify?

The prospect of having certified organic aquaculture products was a hot topic at this year’s Aquaculture 2013 conference in Nashville, Tennessee. Farmed aquatic animals are the only type of food not represented in the marketplace with a United States Department of Agriculture (USDA) Organic seal—a highly recognizable label—although that may change soon.  The USDA is initiating the process for developing an organic aquaculture standard.

At the conference, Mark Bradley of the USDA Marketing Service presented a roadmap for the development of the organic aquaculture standard, which he thinks will take at least 18 months to finalize.   Read More >

Feeding animals to animals: EU weakens rule on feeding animals to farmed fish

Also contributing to this post is Jillian Fry, Project Director, Public Health & Sustainable Aquaculture Project

In a disturbing turn, the EU has again weakened regulations addressing feeding animals to other animals, bringing their rules more in line with flawed U.S. policies. The decision, made earlier this month, revises the animal feed rule to allow swine and poultry carcasses to be fed to farm-raised fish. Read More >

The Question at Smithsonian: Shrimp and Safety

Shrimp trawler

At this summer’s annual Smithsonian Institute dinner, “Sustainable Seafood: Ensuring a Healthy Supply,” the question echoed by many guests was about the safety of imported shrimp. This year, I was an invited guest expert at the dinner, and I was joined at a table with Ed Rhodes, Vice President of Sustainability and Aquaculture Development at Phillips Foods, Inc. Ed and I fielded several questions from guests about sustainable seafood, but the emerging common concern was about imported shrimp. Read More >
