The center doesn\u2019t have MicroCAT recorders or autonomous acoustic sensing gliders. It\u2019s not deploying hundred-thousand-dollar oceanographic mooring lines gathering massive amounts of data.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">So what can MAIC\u2019s three-foot prototype buoy offer that others can\u2019t? It\u2019s easy to clean and costs very little.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">\u201cOne of the big issues for putting anything in the water is biofouling,\u201d said Josh Girgis, an engineer at MAIC based at the <a href=\"https:\/\/dmc.umaine.edu\/\">University of Maine\u2019s Darling Marine Center<\/a> (DMC). \u201cIf you put a sensor in, you can only expect it to work until something starts growing on it.\u201d<\/span><\/p>\n<p><span style=\"font-weight: 400;\">For larger commercial operations, it can be tricky to clean all the bells and whistles that accompany larger equipment. That\u2019s why manufacturers use UV light to kill algae or pumps that cycle water through the system. But all of that requires power, a luxury that small, low-cost autonomous data buoys don\u2019t have. This is why Girgis and the team of researchers opted for a simpler solution &#8211; scrubbing a sponge on the buoy\u2019s sensors.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">Minimal maintenance is among the chief factors that Girgis and Chris Davis, who oversees the Maine Aquaculture Innovation Center, are prioritizing in the creation of their buoy. That\u2019s because their future customers won\u2019t be governments or research scientists &#8211; but Maine\u2019s oyster and seaweed farmers.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">\u201cOur center\u2019s goal is to develop low cost buoys with real-time data collection abilities,\u201d Davis said. \u201cOur target is to create and sell one for about $2,000.\u201d<\/span><\/p>\n<p><span style=\"font-weight: 400;\">From Maine to Florida and from Texas to Washington State, aquaculture farming dots much of the coastal landscape surrounding the states. These shoreline farmers harvest an array of shellfish, including oysters, mussels, clams, and scallops.\u00a0<\/span><\/p>\n<div id=\"attachment_32451\" style=\"width: 406px\" class=\"wp-caption alignnone\"><img loading=\"lazy\" decoding=\"async\" aria-describedby=\"caption-attachment-32451\" class=\" wp-image-32451\" src=\"https:\/\/www.fondriest.com\/news\/wp-content\/uploads\/2020\/07\/EM_oyster-farming_photo-1.jpg\" alt=\"oyster buoy\" width=\"396\" height=\"532\" srcset=\"https:\/\/news.fondriest.com\/wp-content\/uploads\/2020\/07\/EM_oyster-farming_photo-1.jpg 473w, https:\/\/news.fondriest.com\/wp-content\/uploads\/2020\/07\/EM_oyster-farming_photo-1-223x300.jpg 223w\" sizes=\"auto, (max-width: 396px) 100vw, 396px\" \/><p id=\"caption-attachment-32451\" class=\"wp-caption-text\"><span style=\"color: #808080;\">A standard oyster farm in Maine.

(Photo credit: Chris Davis)<\/span><\/p><\/div>\n<p><span style=\"font-weight: 400;\">In Maine alone, shellfish farming is a $20 million industry. Some mom and pop farms might grow 50,000 oysters a year, while commercial operations will yield multiple millions during harvest. But like their landfarming cousins, aquaculture farmers rely on successful harvests to turn a profit. And a profitable season might not arrive until years after getting into the industry.<\/span><\/p>\n<span class='bctt-click-to-tweet'><span class='bctt-ctt-text'><a href='https:\/\/x.com\/intent\/tweet?url=https%3A%2F%2Fwww.fondriest.com%2Fnews%2F%3Fp%3D32446&#038;text=For%20farmers%20targeting%20the%20right%20location%20and%20time%20to%20plant%20their%20oysters%2C%20it%20helps%20to%20rely%20on%20the%20data.&#038;via=FondriestEnv&#038;related=FondriestEnv' target='_blank'rel=\"noopener noreferrer\">For farmers targeting the right location and time to plant their oysters, it helps to rely on the data. <\/a><\/span><a href='https:\/\/x.com\/intent\/tweet?url=https%3A%2F%2Fwww.fondriest.com%2Fnews%2F%3Fp%3D32446&#038;text=For%20farmers%20targeting%20the%20right%20location%20and%20time%20to%20plant%20their%20oysters%2C%20it%20helps%20to%20rely%20on%20the%20data.&#038;via=FondriestEnv&#038;related=FondriestEnv' target='_blank' class='bctt-ctt-btn'rel=\"noopener noreferrer\">Share on X<\/a><\/span>\n<p><span style=\"font-weight: 400;\">\u201cTo do that, you need to develop growth models using environmental controls that regulate how fast shellfish grow,\u201d Davis said. Of the myriad of variables to consider when farming, Davis, an aquaculture farmer himself, says that temperature, salinity (as measured by conductivity), and the amount of food are primary factors.<\/span><\/p>\n<div id=\"attachment_32450\" style=\"width: 434px\" class=\"wp-caption alignnone\"><img loading=\"lazy\" decoding=\"async\" aria-describedby=\"caption-attachment-32450\" class=\" wp-image-32450\" src=\"https:\/\/www.fondriest.com\/news\/wp-content\/uploads\/2020\/07\/EM_oyster-farming_photo-5-600x677.jpg\" alt=\"oyster buoy\" width=\"424\" height=\"479\" srcset=\"https:\/\/news.fondriest.com\/wp-content\/uploads\/2020\/07\/EM_oyster-farming_photo-5-600x677.jpg 600w, https:\/\/news.fondriest.com\/wp-content\/uploads\/2020\/07\/EM_oyster-farming_photo-5-266x300.jpg 266w, https:\/\/news.fondriest.com\/wp-content\/uploads\/2020\/07\/EM_oyster-farming_photo-5.jpg 680w\" sizes=\"auto, (max-width: 424px) 100vw, 424px\" \/><p id=\"caption-attachment-32450\" class=\"wp-caption-text\"><span style=\"color: #808080;\">The online interface farmers will eventually look at when analyzing data collected from buoys in their farms.

If the salinity is too low or temperatures are too high or low, farmers risk wasting years before ever turning a profit.<\/span><\/p>\n<div id=\"attachment_32452\" style=\"width: 610px\" class=\"wp-caption alignnone\"><img loading=\"lazy\" decoding=\"async\" aria-describedby=\"caption-attachment-32452\" class=\"size-large wp-image-32452\" src=\"https:\/\/www.fondriest.com\/news\/wp-content\/uploads\/2020\/07\/EM_oyster-farming_photo-2-600x233.jpg\" alt=\"oyster buoy\" width=\"600\" height=\"233\" srcset=\"https:\/\/news.fondriest.com\/wp-content\/uploads\/2020\/07\/EM_oyster-farming_photo-2-600x233.jpg 600w, https:\/\/news.fondriest.com\/wp-content\/uploads\/2020\/07\/EM_oyster-farming_photo-2-300x117.jpg 300w, https:\/\/news.fondriest.com\/wp-content\/uploads\/2020\/07\/EM_oyster-farming_photo-2.jpg 640w\" sizes=\"auto, (max-width: 600px) 100vw, 600px\" \/><p id=\"caption-attachment-32452\" class=\"wp-caption-text\"><span style=\"color: #808080;\">Another oyster farm out of Maine. When farmers received their seeds, they\u2019re no bigger than a grain of sand. By the time oysters and mussels are fully grown, they\u2019ll have been moved to nets hanging down from buoys where they filter feed. (Photo credit: Chris Davis)<\/span><\/p><\/div>\n<p><span style=\"font-weight: 400;\">However, the year-to-year variability of temperature, conductivity, and food doesn\u2019t change much. Measurements taken at one site will likely be reliable for decision making in the future. That means as long as farmers have the data, they know what to expect.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">\u201cKnowing water temperatures for a site from year to year can help just in managing for the farmer,\u201d Davis said. \u201cWhen do you overwinter your crop? How do you control the density of your shellfish? Of the water temperature? There are ways to use the data to better manage the farm.\u201d<\/span><\/p>\n<p><span style=\"font-weight: 400;\">The buoy that Davis and Girgis want to use would take measurements of all three parameters every quarter-hour, half-hour, or hour, depending on the farmer\u2019s preference, and wirelessly transmit it to a website or one\u2019s cell phone. The data would be communicated from a cellular modem.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">The makeup of the buoy prototypes is essentially a combination of circuit boards contained within the buoy\u2019s hull. Wires connect the circuit boards to probes that protrude from the bottom on an external plate.<\/span><\/p>\n<div id=\"attachment_32449\" style=\"width: 290px\" class=\"wp-caption alignnone\"><img loading=\"lazy\" decoding=\"async\" aria-describedby=\"caption-attachment-32449\" class=\" wp-image-32449\" src=\"https:\/\/www.fondriest.com\/news\/wp-content\/uploads\/2020\/07\/EM_oyster-farming_photo-4-e1595438161549-600x874.jpg\" alt=\"oyster buoy\" width=\"280\" height=\"408\" srcset=\"https:\/\/news.fondriest.com\/wp-content\/uploads\/2020\/07\/EM_oyster-farming_photo-4-e1595438161549-600x874.jpg 600w, https:\/\/news.fondriest.com\/wp-content\/uploads\/2020\/07\/EM_oyster-farming_photo-4-e1595438161549-206x300.jpg 206w, https:\/\/news.fondriest.com\/wp-content\/uploads\/2020\/07\/EM_oyster-farming_photo-4-e1595438161549-768x1119.jpg 768w, https:\/\/news.fondriest.com\/wp-content\/uploads\/2020\/07\/EM_oyster-farming_photo-4-e1595438161549.jpg 915w\" sizes=\"auto, (max-width: 280px) 100vw, 280px\" \/><p id=\"caption-attachment-32449\" class=\"wp-caption-text\"><span style=\"color: #808080;\">The sensor interface housed inside the Maine Aquaculture Innovation Center\u2019s low-cost buoy.

Temperature is measured by a precision thermistor built from a combination of the market and modifications from Girgis.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">However, in later renditions of the buoy, the team hopes to install modified fluorometers, in addition to the conductivity sensor that Girgis built. Future conductivity sensors will be built from readily available components.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">A working model ready for release is still months away as physically fitting modified sensors takes time. However, researchers at the Darling Marine Center envision a future where they could be leased to farmers on an annual basis and the data they collect available to the public.<\/span><\/p>\n","protected":false},"excerpt":{"rendered":"<p>Researchers from Maine\u2019s Aquaculture Innovation Center are building a buoy designed to aid oyster and seaweed farmers along
