Not everyone who wants to start an aquaculture farm has the privilege of picking up their family, leaving their job, and moving to a rural area. Note I didn’t say small town – many of the same rules apply to small towns as large cities. I mean at least a few miles from Main St. Not to mention, there’s lots of vacant lots right now in the sluggish real estate market that could be put to good use. That’s exactly what Rob Ellis decided when he opened Astor Farms in Charlotte, his hometown. He grows tilapia in an abandoned DHL warehouse near the Charlotte airport. And he shared his story at the NC Aquaculture Development Conference last week in New Bern, NC.

Aquaculture in NC: The Global Connection

“We just sold a much bigger one to Denmark, but couldn’t be this style”, said the trade show representative as if he had traveled to the town next door. Aquaculture has its roots in northern Europe in many ways, mainly through connections to the beginnings of domesticating Atlantic salmon. So many American companies are making good money selling their technology and feed to customers around the world that have already made the step into large-scale aquacultural production.

A few countries in particular made their influence known several times: Denmark, Chile, and Canada. Though these have prominent roles in the global capture fisheries as well, their particular geology gave them a head start on salmon that is expanding over into other types of aquaculture.

Aquaculture in NC: Designed Ecosystems

Lest you think aquaculture is like your childhood fish tank on a larger scale, let me remind you of the plecostomus in that tank. You know, the thing that sat stuck to the back of the tank behind the plant so that the family could never quite find it. Yet somehow, despite the fact that you could swear it never moved and could have been a stone decoration rather than an organism, this little helper kept every surface of that tank sparkly clean. Algae-free glass, gravel, and plants. But what if you have large, outdoor ponds and each mouth to feed costs you money if it doesn’t eventually end up as dinner?

This is exactly when you have to stop thinking of these operations as just a tank of fish. They are nestled in the surrounding ecosystem, full of naturally occuring algae – some good and some bad. For eastern North Carolina, both the wind and the tide might carry in some future algae blooms to your tanks, which are well-stocked with nutrient-rich fish poop to feed it. Instead, as NC Aquaculture Conference speaker DE Brune puts it, you have to think of your tanks and ponds as “designed ecosystems”.

This past Friday on the banks of the Neuse in New Bern, NC, people interested in aquaculture in the region gathered to discuss the future. The group packed the ballroom in the Hilton with scientists, extension agents, interested citizens, and of course – producers. The afternoon before some attendees had the chance to visit farms in the area firsthand, one of which I’ve previously written about (White Rock Fish Farm). Friday held talks on the science, economics, and policies of aquaculture. Saturday morning wrapped up with freshwater and saltwater workshops tackling the details of growing fish. Parallel to the whole event was a trade show exhibiting the myriad food options available, water quality testing technology, cages and nets, greenhouses, and contacts for state programs. Friday night, there was proper celebration of aquaculture in the form of the Aquafood festival showcasing products from around the state. Take home message from the event? I left wanting to put a tank in my small Beaufort yard alongside the goats, chickens, and vegetable garden.

Aquaculture in North Carolina: White Rock Fish Farm

“It’s a mom and pop operation, you could say”, described Ted Davis, owner of White Rock Fish Farm in Vanceboro NC. His smile extended ear to ear as he talked about his farm – and the length he goes to ensure his fish are never stressed on their way to the market. The trick? The farm’s small size – 8 ponds – allow the fish to be harvested by hand, each one receiving individual attention on their way to a shipping container. Another thing that makes his farm special? The hybrid striped bass have personality. They’re scared of tractors, eat more when there’s algae in their pond, and elicit hugs from visiting children.

Mr. Davis takes a whole day, with a helper, in harvesting his hybrid striped bass before they begin their frozen journey to Canada. Other growers, including his neighbors down the road, will spend just hours handling even more fish. Hybrid striped bass, however, bleed when they’re stressed. This turns their flesh and fins red, muddling the prized stripes for the marketplace. Plus, stressed fish release stress hormones and other chemicals that consumers can taste. So the White Rock way is to remove as much stress from the fish’s life as possible.

Core Themes for 2012: Focus on nuance

One of the main advantages of blogs is that they allow knowledgeable parties to write in detail about their area of expertise. Information can now come directly from experts to the interested public. This provides an opportunity for those directly involved in an issue to provide context to (and details of) a story. Here at Southern Fried Science, we strive to provide deeper background in topics in which we are knowledgeable, focusing not only on the broader context but on the subtle nuance.

Core Themes for 2012: A renewed sense of wonder

In the past four years, we took our readers from the remote shoals of the Skeleton Coast to the unfathomable depths of the western Pacific. We touched the coasts of every continent, plumbed the depth of every ocean. Throughout this shared journey, the unspoken, implicit rationale, the very heart of our passion, the reason that any of this is worth doing, is that the ocean is awesome. When I say awesome, I don’t mean awesome in some mundane, biblical sense of fear and wonder when staring into the face of god; I’m talking about something much greater than our fragile brains can comprehend.

We have sailed so far, in these four years, and in this voyage I fear that we have found ourselves, like Ishmael, in “the damp, drizzly November of [our] souls.” The conversation at Southern Fried Science has changed, become more cynical, fatalistic, and driven by threats facing the ocean, rather than reasons why we value it. What once was a sea of boundless potential is now cast in bondage to statistics, benefit analyses, weights and measures, action items. In a way, this shift was inevitable. The ocean is in trouble, the world is changing, and the less we understand it, the more we will lose. Without someone to mark the ledger, to take the bearing, the ship is lost.

Core themes of 2012: Underrepresented issues in marine science and conservation

One of the many unfortunate consequences of the decline in traditional media has been a reduction in science reporting. The formerly great CNN science unit closed in 2008, followed soon after by the health and science page of the Boston Globe. Alarmingly few trained science journalists are left, and people without proper training are being asked to cover the few science stories that still make it on the air ( I was once interviewed about shark research by the weatherman from CNN’s “American Morning”). With few exceptions, science and conservation stories are no longer considered a priority to the major news networks and newspapers. However, science is no less important to our everyday lives.

Core Themes of 2012: Challenging the Conventional Narrative

Isaac Newton, after experiencing the bottom end of a falling apple, used that experience to formulate the theory of gravity. The inductive process Newton used is common to the goals of most scientific endeavors and a deeply ingrained part of the human psyche. As humans, we love to generalize. It helps us understand the world around us by categorizing parts of it and explaining natural dynamics by the “laws of nature”. We also stereotype each other by race, hometown, or favorite basketball team. Some would say these tendencies help us prepare – to predict and expect the logical outcome of the set of clues presented in our everyday lives. But just like the reasons your mother told you not to stereotype, sometimes nature has its own surprises that defy prediction, categorization, or law-following. Especially if you don’t quite know what the law is yet.

Core Themes for 2012: Highlighting the Rural Voice

ward creek (10) — Oyster shell, photo by author

Imagine the last time you went to an oyster roast – good food, happy friends, and maybe a delicious smelling fire to warm your toes. Someone brought warm homemade crackers. The youngest in the crowd is both delighted and disgusted at the discovery of a lucky oyster crab in the corner of his oyster shell.

Moments like these that help define what sustainability means – a desire for the continued existence of those oyster roasts. That requires healthy estuaries to make oysters every year, careers that keep people in the community, and healthy local farming for trees and agriculture. Moments like these define the word ‘rural’, where residents are dependent on the natural resources they interact with daily for food and livelihood. This could mean life on a farm in one of the most sparsely populated regions of the country or a piece of the rural carved out of an increasingly urbanized landscape. Rural describes an ethic and a way of life more than any particular location.
