A collaborative project between the agricultural service center of Ly Son district and the Nha Trang Institute of Oceanography has successfully cultured skullcap urchins in cage aquaculture in the Ly Son sea for a year, with a high survival rate of 86% and an average weight of 115g per individual. The urchin has become a culinary specialty and brings significant benefits, but their numbers are dwindling in Quang Ngai due to overmining.
