Dr. John Supan*
Dr. Supan first began work with Louisiana Sea Grant (LSG) in 1984 as an area fisheries agent for Sea Grant and the LSU AgCenter, serving St. Tammany, Orleans and Tangipahoa parishes. In 1985, he became executive secretary-treasurer of the Louisiana Oyster Dealers & Growers Association, the state’s oldest seafood trade association, a position he still holds.

During 1990, Dr. Supan changed career focus and became a Sea Grant research associate to begin working on his doctorate, while on loan to the first commercial oyster hatchery in the Gulf region, Gulf Shellfish Farms of Louisiana. There, he began a 28-year part-time residency on Grand Isle, while managing the oyster hatchery and training oystermen to utilize oyster larvae for remote setting techniques to produce their own seed oysters in order to become less dependent on the public oyster grounds, where production had dwindled due to drought conditions and saltwater intrusion from 1985 to 1991. Once wild seed production rebounded, the commercial venture folded and LSG acquired the facility. The repurposed Gulf Shellfish Farms became the Sea Grant Oyster Hatchery with Supan at the helm by 1993.

During his tenure as director of the hatchery, Supan’s research focused primarily on developing triploid oysters. Dr. Supan’s work was largely collaborative and stretched across state lines and institutions. He credits a 23-year alliance with professor Stan Allen, currently of Virginia Institute of Marine Science, with the production of the first tetraploid oyster broodstock for the Gulf region in 1998, which drives triploid production across the Gulf today.

In 2015, Dr. Supan transitioned the Sea Grant Oyster Hatchery into the Sea Grant Oyster Research Laboratory located within the Michael C. Voisin Oyster Hatchery on Grand Isle, which was built with National Resource Damage Assessment funding resulting from the BP oil spill and currently owned and operated by the Louisiana Department of Wildlife and Fisheries. The hatchery, designed by Dr. Supan, is the first in the world to incorporate both RAS technology and LED algal lighting to produce oysters. Dr. Supan retired on December 31st 2017 after more than 30 years with LSU. (*Information and picture from: https://www.laseagrant.org/2018/supan-announces-retirement/)
