Sand tiger sharks — a species of concern prohibited from recreational catch in US waters — are being legally harvested from Delaware Bay by private collection companies and sold to foreign aquariums. Eighty sharks were removed between 2018 and 2024, with the collection rate surging from two in 2018 to 40 in 2023. Nearly all went overseas, primarily to China and the United Arab Emirates. The mechanism is a regulatory gap between federal and state permitting. Private companies obtain an exempted fishing permit from NOAA Fisheries, then a scientific collecting permit from Delaware's DNREC. The state treats federal approval as sufficient evidence of sustainability, and NOAA says it reviews applications on a "case-by-case basis" against an overall quota. Neither agency tracks what happens to the sharks after they leave — whether they sicken, die, or reproduce in captivity. One company dominates the trade. Dynasty Marine, a Florida-based live animal supplier, began collecting in Delaware in 2021 and took 71 sharks between 2022 and 2024. Records show 35 harvest requests in 2025, most destined for China. Recipients include SeaWorld Abu Dhabi, Dubai Aquarium and Underwater Zoo, Sea Life Busan in South Korea, Aquaria Phuket in Thailand, and Guangzhou Ocean World in China. Dynasty Marine says all collections comply with federal and state permits and that the animals "play a vital role in educating millions." The core contradiction is sharp. An angler who hooks a sand tiger shark must release it by law. A private company can catch the same animal from the same water, fly it to Abu Dhabi, and sell it. The US invested decades of protective regulation to build one of the few remaining non-critically-endangered populations worldwide. Private collectors are now monetizing that conservation success while bearing none of its costs. Scientists at the University of Delaware, Delaware State University, and the University of Rhode Island published a study in Frontiers in Conservation Science documenting the trend. Their central concern: the sand tiger population has never had a formal assessment, so no one actually knows whether these removals are sustainable. Many collected sharks are large juveniles or near-mature adults that would soon reproduce if left in the wild. Sand tigers reach sexual maturity at six to ten years and produce just one or two pups every two to three years — one of the lowest reproductive rates of any shark species. Delaware's DNREC calls the collection increase an "emerging concern" but says federal action would be needed. NOAA points to its quota system. Neither agency has conducted the population assessment that would determine whether 40 sharks a year is safe or catastrophic. As researcher Dewayne Fox puts it: "We have protected the habitat and yet we are going to allow some out-of-state company to come in, catch these animals and then ship them all the way around the world and make money. Everybody else is benefiting from our conservation success." The pattern is textbook extraction: public investment in conservation creates a valuable biological asset; a regulatory gap allows a private intermediary to capture that value; the asset leaves the jurisdiction permanently; and no feedback loop exists to measure the damage. The countries buying these sharks depleted their own populations through overfishing and habitat degradation. The US is now subsidizing their aquarium industries with animals its own citizens are prohibited from touching.
