Public aquariums can function as applied hatcheries, accelerating marine finfish aquaculture by pairing unique broodstock access with established animal care, research, and training capacity. Since 2023 we have organized a multi-institution learning and production network spanning more than 50 professionals across aquarists, veterinary staff, educators and aquarium leadership. Partners are developing or expanding broodstock systems for priority species, standardizing egg collection and handling, and operating modular larval rearing systems with coordinated live-feeds production. This consortium has met more than 65 times to date, delivering 48 presentations focused on collaborative problem-solving focused on broodstock conditioning, egg quality, first-feeding, and shipping juveniles. We have optimized diets for improved hatch quality and larval performance by assessing more than 200 fatty-acid samples from 10 or more species. Early results include increasing exhibit-sourced spawns, survival to settlement for several target taxa, and distribution of aquarium-reared juveniles among Association of Zoos and Aquariums members. In parallel, partners are testing mitigation strategies through light regime, surface condition, and flow adjustments to counter common deformities. The distributed production model reduces reliance on wild collection, creates a pipeline of aquacultured juveniles for exhibits, and generates open, transferable rearing guides that can inform commercial trials. This talk will synthesize how a national aquarium-led network can expand reliable marine larval production, accelerate technology transfer to interested producers, and strengthen workforce development. We will also discuss measurable outreach activities through digital storytelling, educator training, rearing guides, and on-site interpretation to advance public understanding of U.S. marine finfish aquaculture and improve the mission and sustainability of public aquariums.
