10-year battle of sea urchins vs. invasive seaweed

The first hatchery-raised sea urchins outplanted in Kāneʻohe Bay are 10-years-old, and the University of Hawaiʻi at Mānoa Pacific Cooperative Studies Unit (PCSU) and the State of Hawaiʻi Division of Aquatic Resources (DAR) are celebrating the milestone anniversary. The sea urchin hatchery, funded by the National Oceanic and Atmospheric Administration (NOAA) and DAR, successfully transplanted the first cohort in January 2011 and has since released 600,000 sea urchins across the state.
