Hubbs-SeaWorld Research Institute, a 501(c)(3) marine science organization founded in 1963, operates its Carlsbad hatchery facility on Garfield Street at the edge of Agua Hedionda Lagoon. The 22,000-square-foot Leon Raymond Hubbard Jr. Marine Fish Hatchery anchors the Ocean Resources Enhancement and Hatchery Program, a fisheries-replenishment initiative contributing to Carlsbad's marine-education cluster alongside SEA LIFE Aquarium. Since the 1990s, the OREHP has released nearly three million juvenile white seabass into Southern California coastal waters, making it one of the state's longest-running stock-enhancement efforts. In 2025, NRG Energy donated 6.6 acres of lagoon-adjacent land to the institute, doubling its Carlsbad footprint and enabling expansion into seaweed, shellfish, and sea cucumber aquaculture within integrated multispecies systems. Hatchery-raised white seabass are cultured in open-water net pens before release, sharing the same Agua Hedionda waterway where California Watersports operates its kayak and jet-ski fleet in the outer basin. The Dick Laub Fisheries Replenishment Program, funded by a $900,000 private donation, targets pilot-scale production of multiple nearshore species to supplement the core white seabass stock enhancement across Southern California's depleted coastal fisheries.
