South Korea's South Jeolla Province has started the process of recovering resources for barley prawns, a high-value fish species, as the country's domestic shrimp production is heavily dependent on natural production and has seen a significant decline from 59 tons in 2016 to 12 tons in 2021. To combat this, the Jeonnam Provincial Institute of Maritime Science and Fisheries has released 500,000 prawn seeds into coastal tidal flats. Since 2015, the institute has released 14 million shrimp to support the declining population and is also conducting research on artificial sexual maturation induction. The institute plans to continue developing high-income varieties and increasing the number of seeds released.
