Highlights from Aquaculture America 2015

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

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 >

New Orleans Groups Awarded Grants for New Farm and Food Center

I want to congratulate my friends at the Recirculating Farms Coalition who were recently awarded two grants to construct an Urban Farming and Food Center in downtown New Orleans.   The center will be home to a community garden, fruit trees, aquaponics and hydroponics.  These last two are methods for raising fish and edible plants in soil-free recirculating water systems, and similar to the approach we have taken in our Center for a Livable Future Aquaponics Project in Baltimore’s Cylburn Arboretum.

RFC says in the press release, “The Center will be a hub for research, education, training, and community interaction on growing, marketing, and preparing healthy food in the city and beyond.” The center will be built and run in a collaboration between RFC and the New Orleans Food and Farm Network.  Funding for the project comes from the Claneil Foundation and the Blue Cross and Blue Shield of Louisiana Foundation.


Grocery Store Shrimp Contains Drug Resistant Bacteria

A new U.S. Food and Drug Administration study has found that farmed shrimp can be added to the list of animal protein sold in grocery stores that harbors multi-drug resistant bacteria. That list, now being joined by farmed shrimp, includes pork, chicken, ground turkey, and ground beef.

The article was published in the peer-reviewed International Journal of Food Microbiology in February 2012, and while it has not been covered by the mainstream media, given the importance of the study findings I think this article deserves more attention. Read More >

Recirculating Farms Coalition: Fish Farms Meet Agroecology

Sahib Punjabi's recirculating farm in Winter Park, Fla.

The United States needs better food systems, and it needs more jobs. Aquaponics, a relatively new type of urban food production model, can give us both—sustainable food and green jobs.

Currently, the U.S. imports about 85 percent of our seafood, a large fraction of which is produced in overseas fish farms, by a process called aquaculture. Another 10 percent is “domestic wild catch,” which is made up of seafood caught by U.S. fishermen (NOAA). The remaining 5 percent comes from U.S. aquaculture.  As global wild catch declines, aquaculture is steadily increasing as a viable replacement, although some aquaculture operations are criticized for being sited in open water or rivers, where fish escapes, exchange of fish diseases between farmed and wild fish, and environmental pollution are of concern.

But there is a different approach to aquaculture that addresses many of these concerns: aquaponics. Aquaponics is typically land-based, closed-system farming that is designed with the principles of agroecology in mind— fish species and vegetable crops are raised together in harmony— because fish waste serves as liquid plant fertilizer and plants strip the water of chemicals that are harmful to fish.

Agroecology, a method for integrating biological systems into agriculture, is widely recognized as a potential solution for increasing farm productivity and environmental sustainability of agriculture. Olivier De Schutter, UN Special Rapporteur on the Right to Food, is strongly in favor of the agroecology approach, in which farmers create “complex farming systems that replicate the complexities of nature.” Read More >

India develops sound policy on antibiotic use in aquaculture and food animals

India is the most recent country to address the public health concerns associated with the use of non-therapeutic antimicrobials in food animal production, and in doing so, may just leap-frog the United States.

India’s Directorate General of Health Services recently released a policy document entitled “The National Policy for Containment of Antimicrobial Resistance (NPCAR)”, which outlines approaches for targeting both human and animal antimicrobial usage, infection prevention and control, education and training on administration of antimicrobials, antimicrobial resistance surveillance systems, and enforcement.

It is a move that should be viewed as very positive, if significantly overdue” says Ed Broughton, Research and Evaluation Director of the USAID Health Care Improvement Project at University Research Company and former doctoral fellow at the Johns Hopkins Center for a Livable Future.

Among the proposed policies specific to food animal production, the NPCAR recommends banning non-therapeutic usage of antimicrobials in food animals, labeling requirements in food exposed to antimicrobials, and banning over-the-counter (OTC) sale of antimicrobials. It is not clear whether the OTC sales ban would also apply to purchases of antimicrobials in feed (i.e. medicated feed) for food animals. Read More >
