Study indicates far more hatchery fish in California ocean waters than previously thought.
A new study four years in the making by a team of marine fisheries and genetic scientists indicates that many more white seabass in California ocean waters emanate from the Hubbs-SeaWorld Research Institute (HSWRI) hatchery in Carlsbad, California, than previously thought.
Presented at the Aquaculture 2022 conference in early March in San Diego, California, the preliminary findings contrast sharply with a 2017 study that suggested less than 1 percent of white seabass caught in California were from the Carlsbad operation, known officially as the Ocean Resources Enhancement and Hatchery Program (OREHP).
