If you develop it \u2014 and if you seed it \u2014 perhaps they will come.<\/p>\n\n\n\n

That\u2019s what some University of North Carolina Wilmington<\/a> scientists hope their research will do: Build the oyster aquaculture industry in North Carolina.<\/p>\n\n\n\n

Seed funding from North Carolina Sea Grant<\/a> has jump-started two projects that could help the state achieve this goal. These UNCW researchers are developing building blocks that might make it easier and more efficient for those who want to grow oysters in the state.<\/p>\n\n\n\n

An online siting tool to help identify potential new aquaculture lease sites and a research shellfish hatchery are parts of a larger effort that could make North Carolina among the nation\u2019s leaders in oyster aquaculture.<\/p>\n\n\n\n

“The siting tool and hatchery are essential for the expansion of the oyster aquaculture industry in the state,” says Chuck Weirich, Sea Grant marine aquaculture specialist. “The tool will greatly assist potential oyster growers in finding suitable locations for their farms. The hatchery research being conducted at UNCW is determining the best native oyster lines for aquaculture production in North Carolina’s waters.”<\/p>\n\n\n\n

With only one commercial shellfish hatchery currently operating in North Carolina, many growers in the state are using seed from Virginia to meet stocking requirements. Those looking to get into the business have to sort through complex rules and regulations that specify where they can get leases to start their operations.<\/p>\n\n\n\n

\u201cAll we have to do is look at what the other successful states have done and emulate it. We don\u2019t have to reinvent the wheel with this,\u201d says Jay Styron, president of the N.C. Shellfish Growers Association<\/a>. \u201cWe\u2019ve got successful blueprints from many other states. It\u2019s not rocket science. It\u2019s not like it\u2019s a high-tech business either. It\u2019s truly very simple.\u201d<\/p>\n\n\n\n

But first, where does one begin?<\/p>\n\n\n\n

NAVIGATING WATERS<\/h2>\n\n\n\n

Starting a shellfish aquaculture venture in North Carolina can be overwhelming. The state offers lots of promising locations but choosing one can be limited by personal, environmental and regulatory considerations.<\/p>\n\n\n\n

How would you begin identifying a good lease site? Or even know where to start looking?<\/p>\n\n\n\n

\"UNCW
Users praise the siting tool for providing a variety of useful information at their fingertips. Source www.uncw.edu\/benthic\/sitingtool.<\/figcaption><\/figure>\n\n\n\n

Troy Alphin, a biologist who studies oysters at UNCW, is familiar with this dilemma.<\/p>\n\n\n\n

\u201cThe question we get 90 percent of the time when we run into people is, \u2018Where\u2019s a good place to grow oysters and clams?\u2019 \u201d he says.<\/p>\n\n\n\n

To help potential growers navigate the state\u2019s regulatory \u2014 and actual \u2014 waters, Alphin led the development of the North Carolina Shellfish Aquaculture Siting Tool, available at www.uncw.edu\/benthic\/sitingtool<\/a>. The online tool can help users identify possible lease sites that meet their needs and that could be acceptable to state regulators.<\/p>\n\n\n\n

It presents data from many sources that have to be considered during the lease application process, accomplishing a lot of the initial groundwork for aspiring growers. Available information includes water quality, depth, salinity, restricted areas and current operations. The tool is a good starting point, but users also have to consider actual, in-the-field conditions, Alphin notes.<\/p>\n\n\n\n

The initial work was funded by the National Sea Grant Aquaculture Competition through North Carolina Sea Grant. The overall project was led by Marc Turano, a former North Carolina Sea Grant extension specialist.<\/p>\n\n\n\n

In addition to providing seed money to begin work on the siting tool, this grant resulted in a survey of the state\u2019s aquaculture operations. The funding also enabled Turano to bring several individuals \u2014 including Chris Matteo who went on to establish Chadwick Creek Oysters<\/a> \u2014 on a tour to learn how Maryland and Virginia oyster growers developed and grew their businesses.<\/p>\n\n\n\n

\u201cIt\u2019s a really good example of where the North Carolina Sea Grant funding provided the nucleus,\u201d explains Martin Posey, a benthic ecologist at UNCW who worked with Alphin on the siting tool. Posey notes that the team continues on funding from other sources, particularly UNCW. \u201cWhat we have now is several generations beyond the original project, and it\u2019s a much more advanced tool for understanding where appropriate habitats are.\u201d<\/p>\n\n\n\n

ONE-STOP SITING<\/h2>\n\n\n\n

North Carolina provides for the private use of its public waters \u2014 the water column or unproductive bottom \u2014 for shellfish culture through leases. This program is administered by the N.C. Division of Marine Fisheries<\/a>, or DMF.<\/p>\n\n\n\n

\u201cThe waters out there are public-trust waters. They belong to the people of North Carolina,\u201d says Steve Murphey, chief of the DMF Habitat and Enhancement Section<\/a>. \u201cThe charge to us is to make sure that person or franchise or whoever gets that lease uses it for the purpose intended, which is the commercial production of shellfish.\u201d<\/p>\n\n\n\n

He notes that the tool could help smooth the lease application process. \u201cIt\u2019s a great compilation of a lot of different data layers that have been developed by various government agencies and academic areas. It allows prospective leaseholders to go in and narrow down where might be a good place to put a lease \u2014 or better yet, a good place not to put a lease,\u201d Murphey says.<\/p>\n\n\n\n

\u201cWhat this does is to allow people to do some homework up front before they get started with the application process,\u201d he adds. It saves time for the person seeking the lease and for DMF, which has to review the application.<\/p>\n\n\n\n

\"Alphin

This includes conducting a site investigation for each proposed site to ensure that it does not contain a natural shellfish bed or submerged aquatic vegetation, which serves as important habitat.<\/p>\n\n\n\n

\u201cIt puts it all together in one-stop shopping,\u201d says Styron, who also owns Carolina Mariculture Co.<\/a> on Cedar Island. The oyster grower helped Alphin confirm the accuracy of the tool and helped make the system more user-friendly.<\/p>\n\n\n\n

In addition, Styron has assisted several people who are using the tool to \u201cput eyes on the water\u201d to determine which locations could be potential shellfish leases.<\/p>\n\n\n\n

Kure Beach resident Tim Holbrook used the tool to help him identify a lease site. \u201cI had a tremendous amount of information at my fingertips to select the location,\u201d he notes. He had access to valuable data, such as salinity, mean water depth at low tide, water quality and presence of submerged aquatic vegetation.<\/p>\n\n\n\n

\u201cTo be able to fly in from a 20,000-foot view to a view that is 20 feet by 20 feet and also see the orthoimagery and all the details is something you could never do in a boat,\u201d Holbrook adds.<\/p>\n\n\n\n

He started his search in January this year. Using the tool \u2014 and aided by contacts he met at the 2015 N.C. Aquaculture Development Conference in New Bern \u2014 he identified and submitted a request for a lease site to DMF in the spring.<\/p>\n\n\n\n

“I found it unbelievably helpful. I would spend hours and hours on it before I would go out in the field because it just saved me so much time,” he recalls.<\/p>\n\n\n\n

Holbrook anticipates getting DMF approval to set seed in early September.<\/p>\n\n\n\n

The coastal resident envisions this as a family venture. “I have two teenaged boys, and I look forward to having them out on the farm,” he explains, “so they can learn about sustainable farming that enhances the environment.”<\/p>\n\n\n\n

Deb Bettini is a vegetable gardener who was looking to grow oysters on a small scale near her family home on Topsail Island. Alphin and his team, whom she met at the 2014 aquaculture conference, helped her use the siting took to search for potential sites.<\/p>\n\n\n\n

“I found the tool to be easy to use. And the graphics that they had were good for pointing out the space that was available,” Bettini notes.<\/p>\n\n\n\n

The results altered her plans. “It pointed me to the fact that there already were oyster leases in that area,” she explains. Her solution? Find a neighbor with a lease who could sell oysters to her.<\/p>\n\n\n\n

\u201cIt helped me to find what I was looking for, which was local seafood produced by a local waterman,\u201d says the local food enthusiast.<\/p>\n\n\n\n

The tool officially launched in October 2014. However, Alphin and graduate student Keith Hall already are working on the next feature \u2014 a suitability index.<\/p>\n\n\n\n

\u201cIt wasn\u2019t enough for me to tell them where everything is and whether or not it was supporting shellfish. They wanted us to score it,\u201d Alphin recalls.<\/p>\n\n\n\n

The team tested this prediction system by comparing the tool\u2019s results to active leases. They\u2019ve also used data from the UNCW Shellfish Research Hatchery<\/a> to check the suitability ranking. The index is being refined and currently is not available on the public version of the tool.<\/p>\n\n\n\n

The team also continues to update the online version of the tool as the data sets change.<\/p>\n\n\n\n

\u201cThis is a living, developing tool. So, as we get more data, we\u2019ll push it out there as folks give us feedback,\u201d Alphin notes. \u201cIt\u2019s critical to know when these things change. The only way we can be sure of seeing no change is not to look.\u201d<\/p>\n\n\n\n

BUILDING BROODSTOCK<\/h2>\n\n\n\n

Since 2012, Ami Wilbur, director of UNCW\u2019s hatchery, has been focusing on selectively breeding North Carolina oysters.<\/p>\n\n\n\n

\"Ami<\/a>

Her goal is to develop lines of local oysters for use in North Carolina by the state\u2019s growers. In addition, she wants to determine if oysters from local waters are better adapted to, and grow faster in, conditions in North Carolina.<\/p>\n\n\n\n

The first support for this selective breeding work came through the N.C. Blue Crab and Shellfish Research Program, administered by Sea Grant.<\/p>\n\n\n\n

\u201cThe Sea Grant funding that I received for the hatchery has been instrumental in initiating our program. When the hatchery was initially constructed, there were no operations funds. So our initial efforts to pursue the goals the planning committee had set for the hatchery were largely funded by Sea Grant,\u201d Wilbur says.<\/p>\n\n\n\n

In 2016, she will produce the third generation of the Sea Grant lines. They were started using wild oysters from the Crab Hole oyster sanctuary in the Pamlico Sound, as well as reefs in Stump Sound, Hewletts Creek and Lockwood Folly River.<\/p>\n\n\n\n

Funding from UNCW and the New Hanover County Farm Bureau has enabled the research hatchery to continue the breeding program.<\/p>\n\n\n\n

Each generation takes about two years. Oysters are spawned in the hatchery, and their offspring are initially grown in indoor tanks and later, at the facility\u2019s outdoor farm. Once the young oysters reach about 9 mm, Wilbur sends some to industry partners who provide information on how the oysters do in different locations.<\/p>\n\n\n\n

When the oysters are mature, they are returned to the hatchery. Those that exhibit specific desired characteristics are spawned to produce the next generation. The selection criteria include disease resistance, quick growth and the deep-cupped shape prized by the restaurant industry.<\/p>\n\n\n\n

The hatchery staff also is evaluating the performance of triploid oysters, with three sets of chromosomes instead of two. These oysters grow faster and are marketable year round. The production process involves patented technology from Virginia. This means that the hatchery\u2019s triploids result from crossing a North Carolina female oyster with a male from Virginia. Initial results indicate that the triploids outgrow the diploids.<\/p>\n\n\n\n

\u201cI\u2019m 100 percent in support of the hatchery because I think they\u2019re doing the work now that is going to pave the way for us down the road,\u201d says Joey Daniels, who heads Bodie Island Oysters. \u201cThe groundwork is being laid for an industry to take off here. And it\u2019s important that it continues.\u201d<\/p>\n\n\n\n

His business is one of several helping the UNCW hatchery grow out the oysters as part of the research.<\/p>\n\n\n\n

Wilbur points to Virginia\u2019s oyster industry that has grown by leaps and bounds in the past decade or so. \u201cThat\u2019s largely on the back of a program like this one, started at the Virginia Institute of Marine Science,\u201d she says. Her hope is to match \u2014 or even surpass \u2014 that achievement.<\/p>\n\n\n\n

But she\u2019s not content to rest on these bivalves alone. Based on industry input, Wilbur also is branching out, raising local lines of bay scallops and sunray venus clams.<\/p>\n\n\n\n

\u201cOur research focus is the idea of providing farmers with some ability to diversify their crops so that they’re not just growing oysters. And these are two candidate species that they’re expressed interest in,” she notes.<\/p>\n\n\n\n

“This is not just an exercise in scientific curiosity. It really does have real-world impact,” Wilbur stresses. “Basic science can happen in the hatchery, but the focus is on applied research that can do good things for North Carolina.”<\/p>\n\n\n\n

PLANNING FOR GROWTH<\/h2>\n\n\n\n

Wilbur is not the only one who singles out Virginia as an example to follow. Many local shellfish experts and growers believe that North Carolina can \u2014 and should \u2014 build its oyster aquaculture industry to rival that of its northern neighbor.<\/p>\n\n\n\n

In 2014, North Carolina’s oyster aquaculturists brought in about $343,000, while Virginia’s industry was worth $17.1 million. In 2005, both states’ oyster aquaculture industries had similar outputs. Virginia’s farm-gate value totaled about $240,000 while North Carolina’s was approximately $260,000.<\/p>\n\n\n\n

To achieve Virginia’s level, experts believe North Carolina must expand aquaculture operations and support hatcheries that can provide local oyster seed for various ventures.<\/p>\n\n\n\n

Weirich is seeking additional areas where Sea Grant can contribute to industry growth. He has received a 2015 National Sea Grant Aquaculture Competition grant that includes support to develop demonstration facilities to evaluate gear types for off-bottom oyster culture and production of other shellfish species for industry diversification. These facilities also could serve as sites for training sessions to transfer knowledge and technology to growers. See the Tiding on page 3 for details of this new funding.<\/p>\n\n\n\n

But those ae in the near future. For now, the siting tool and research hatchery are addressing different parts of this effort.<\/p>\n\n\n\n

“There’s increased interest in exploring the farms. There’s increased interest in pursuing sites. That’s clear by contacts we’re getting, by what we hear from DMF,” Posey says. “The conversation and the interest have ramped up dramatically. The actual existence of larger culture farms hasn’t gotten there yet \u2014 but that’s a progression of time.”<\/p>\n\n\n\n

He believes that the siting took will help those interested in aquaculture, particularly those unfamiliar with the coast. “It’s always been a matter of transforming that interest into people doing it,” he notes. “We’ve lots of room for expansion and still keep our pristine and wonderful resource.”<\/p>\n\n\n\n

Weirich welcomes the new blood. “The growth of the industry will be largely dependent on getting new people involved.<\/p>\n\n\n\n

The current growers are doing a great job, but to realize the increase in oyster aquaculture that Virginia has, we need more growers in North Carolina. And the tool can help with that.\u201d<\/p>\n\n\n\n

Alphin fields calls from many noncoastal residents who want a farm. If the hits on the siting tool website are any indication \u2014 about 500 to 1,000 page views per month since its launch \u2014 many people are interested.<\/p>\n\n\n\n

\u201cIt\u2019s like penguins at the edge of the ice,\u201d Posey explains. \u201cWe\u2019ve got to get a few going to get the others going.\u201d<\/p>\n\n\n\n

SUPPORTING DEMAND<\/h2>\n\n\n\n

But once the industry starts to grow, North Carolina needs to have sufficient resources \u2014 meaning oyster seed \u2014 to support its own entrepreneurs.<\/p>\n\n\n\n

\u201cIt\u2019s very important to get our own research hatchery to get the bugs worked out from the specific lines and then get hatcheries in North Carolina to start producing seed for North Carolina growers,\u201d Styron says.<\/p>\n\n\n\n

The one commercial hatchery in North Carolina does not produce enough seed to meet the demand of local aquaculture operations. So the state\u2019s growers turn to Virginia or other states for their needs.<\/p>\n\n\n\n

This dependence is neither advisable nor sustainable, as demand increases or during times of inevitable seed shortage. \u201cMore and more people are going to be competing to get that seed. And Virginia, they\u2019re going to take care of themselves first. That\u2019s understandable,\u201d oyster grower Daniels says.<\/p>\n\n\n\n

And that\u2019s where the research hatchery can help. Its goal is to introduce tested lines of locally sourced oyster seed and make the North Carolina oyster growing industry self-sufficient.<\/p>\n\n\n\n

\u201cWe\u2019re finding that a lot of North Carolina-specific lines are doing better than the actual Virginia lines,\u201d Styron says of the oysters he is growing out for the UNCW hatchery. \u201cIf that shows something local is going to perform better, that\u2019s going to help us in the long run.\u201d<\/p>\n\n\n\n

Researchers and growers also note that regulatory changes could encourage the oyster aquaculture industry. This topic was discussed at the N.C. Oyster Summit in early 2015<\/a> and also in the N.C. General Assembly.<\/p>\n\n\n\n

Murphey says DMF supports aquaculture but the agency has a duty to discharge. \u201cWe want to see people succeed in it but we\u2019re also very diligent about making sure that we are good custodians of the public trust.\u201d<\/p>\n\n\n\n

Styron, for one, would like to see more legislative action \u2014 and soon. \u201cIt\u2019s a nonpartisan issue too. Both sides of the aisle like oysters. That\u2019s the great thing. And both sides of the aisle like the coast. It\u2019s all positive,\u201d he says.<\/p>\n\n\n\n

Weirich advises patience, noting that the issue is starting to gain some traction. \u201cLegislators realize the importance of oyster aquaculture to North Carolina,\u201d he notes.<\/p>\n\n\n\n

The environmental benefits a booming oyster aquaculture industry can bring to the state is one topic experts and growers hope will influence the dialog on regulatory changes to support the oyster aquaculture industry.<\/p>\n\n\n\n

\u201cI see this as a win-win,\u201d Wilbur says. \u201cThere\u2019s a tremendous opportunity for economic development and there\u2019s also a tremendous positive environmental impact from oyster aquaculture.\u201d<\/p>\n\n\n\n

Oysters in the water, whether wild or cultured, filter out impurities and clean the water. They also provide good hiding places and nurseries for economically important juvenile fish.<\/p>\n\n\n\n

\u201cI\u2019ve been working here for 20 years. Everybody wants to know what they need to do to bring back the fish or bring back the oysters. It\u2019s clean up the water quality,\u201d Alphin says. \u201cGrowing shellfish is the ultimate green industry. It leaves the water cleaner than when the water arrived. You\u2019re not adding food. They pull their food right out of the water column. They promote water clarity. They promote stability of the bottom,\u201d he adds.<\/p>\n\n\n\n

\u201cAt that point, I look at this and I have a hard time seeing a downside to promoting shellfish culture for saving our coastal resources. It just makes perfect sense to me.\u201d<\/p>\n\n\n\n
