February 13, 2026 Oysters have shaped our estuaries for centuries. They’ve supported working waterfronts, filtered our waters, and built reefs that shelter fish and crabs. Today, they sit at the center of important conversations about coastal economies, water quality, public trust waters, and the future of our fisheries. This series will explore the full story. We’ll examine the remarkable life cycle of an oyster, including some surprising biological traits few people know about. We’ll look at the differences between wild harvest and cultured production, share the latest economic trends shaping the industry in North Carolina and across the country, and discuss why water quality remains inseparable from oyster success. Whether you harvest them, grow them, study them, eat them, or simply value clean water and thriving estuaries, oysters connect us all. Part 1: Nature’s Estuary Engineer Few species tell the story of our coast like the oyster. Once so abundant that reefs were navigational hazards, oysters helped shape North Carolina’s estuaries and the communities built around them. They fed families, sustained working waterfronts, and formed the backbone of coastal economies. Historic oyster reefs once spanned tens of thousands of acres throughout North Carolina’s estuaries. Modern mapping has identified roughly 22,000 acres of shell bottom in coastal waters, a tangible reminder of what was and what restoration hopes to rebuild. Over time, habitat loss, water quality challenges, and intense harvest pressure dramatically reduced wild oyster populations. Yet today, oysters are at the center of one of the most hopeful stories in coastal restoration and sustainable seafood. Oysters do more than live in estuaries; they build them. Here in North Carolina, both public reef harvest and private lease production play important roles. Wild oysters connect us to heritage and tradition. Cultured oysters help meet rising demand and provide economic stability for coastal communities. Together, they generated $8.15 million in dockside sales in 2024, the highest value on record. In this series, we’ll explore how oysters grow, how they support clean water, how cultured production works, and how the oyster economy is transforming both nationally and here at home. Oysters are more than seafood on ice. They are living infrastructure, and one of the clearest examples of how conservation and coastal livelihoods can move forward together. Next week: Wild harvest and cultured oysters, two paths to the same plate. Hooked on a Feeling: Inside the Fish Heart Valentine’s Day isn’t just for humans. It’s also a chance to marvel at the diversity of hearts throughout the animal kingdom, especially beneath the waves. Fish hearts aren’t simply slower versions of ours; they’re finely tuned engines shaped by cold water, long migrations, sudden bursts of speed, and life in low-oxygen environments. Unlike mammals, most fish have a two-chambered heart—one atrium and one ventricle—arranged in a loop. Blood flows from the heart to the gills to collect oxygen, then out to the body and back again. But simple doesn’t mean boring. Off North Carolina’s coast, bluefin tuna move like living torpedoes. Built for endurance and speed, they have large, muscular hearts capable of powerful contractions. In colder waters, their heart rates can climb toward 200 beats per minute to meet the oxygen demands of long migrations and explosive chases. Here’s the twist: bluefin are partially warm-bodied, keeping parts of their muscles warmer than the surrounding water while their hearts remain at ambient temperature. Even so, their cardiovascular systems perform efficiently from chilly Cape Hatteras waters to warmer offshore currents. Closer to shore, species such as flounder, red drum, and striped bass live differently. Their heart rates are slower, rising when feeding or escaping predators. Cold winter waters can slow rhythms dramatically, which is one reason why sudden temperature swings can stress coastal fish species. Some marine creatures take things even further. The deep-sea hagfish have a primary heart plus several accessory pumping structures that move blood through their low-pressure circulatory system. Octopuses have three hearts—two for the gills, one for the body. Heart design tells a story of habitat, temperature, and survival. So while candy and flowers steal the spotlight this Valentine’s Day, remember, some of the most remarkable hearts are beating beyond the shoreline. |

Litopenaeus setiferus, commonly called white shrimp or green tails, are primarily harvested in the estuarine and nearshore ocean waters. They are light gray with green-tinted tails, and their antennae are 2.5 to 3 times their body length. Evidence suggests that warming water temperatures are contributing to an increased abundance of white shrimp in North Carolina and states to the north. North Carolina has historically had the northernmost commercially viable population of white shrimp. However, in 2022, Virginia began permitting a limited offshore shrimp trawl fishery due to the consistent presence of white shrimp in its nearshore ocean waters. Similarly, North Carolina’s harvest of white shrimp has increased over time, with the species surpassing brown shrimp as the majority species of harvest for the first time in 2005 and regularly doing so ever since. In 2023, 3.8 million pounds of white shrimp were harvested from North Carolina waters, with annual landings surpassing 9 million pounds as recently as 2017. Brown Shrimp Fa
rfantepenaeus aztecus, commonly called brown shrimp or summer shrimp, are primarily harvested in the estuarine waters of North Carolina. They typically remain low in the water column and depend on certain water temperatures to trigger biological changes. Specifically, decreasing water temperatures prompt overwintering behavior, during which they bury themselves in sediment for protection from the cold. Evidence suggests that warming water temperatures may disrupt this behavior, leading to higher natural mortality and greater variability in landings. Reported brown shrimp landings in North Carolina exceeded 2.7 million pounds in 2023, and were as high as 6.3 million pounds as recently as 2015. Pink Shrimp
Farfantepenaeus duorarum, commonly called pink shrimp or spotted shrimp, are often found in sand or sand-shell bottom habitats. They are easily identified by their pink color and a dark-colored spot between their third and fourth abdominal segments. Similar to brown shrimp, smaller pink shrimp remain in estuarine waters during the winter and bury themselves in the sediment to protect against cold temperatures. In the past, pink shrimp made up a sizable percentage of the total shrimp harvest in North Carolina. However, landings have been low in recent years, with just over 29,000 pounds landed in 2023. Pink shrimp have accounted for less than 20% of the North Carolina harvest since 1993, and less than 10% in most years.
There is another species of shrimp that is occasionally captured in North Carolina, the invasive tiger shrimp (Penaeus Monodon). Native to Southeast Asia, tiger shrimp were first caught off the Carolinas in 1988, following an accidental release from an aquaculture facility. They can grow up to 13 inches and have a rusty brown to black coloration with distinct banding along their backs. North Carolina’s first documented inshore capture of tiger shrimp occurred in 2006 when five specimens were collected from Pamlico Sound. Tiger shrimp are now considered an established species along the southeast and Gulf coasts.
