       In order to protect fishery resources, it is essential to increase the survival rate of fishery species during the larval stage. Otolith analysis is an effective way to examine growth during the larval stage. I would like to contribute to the SDGs (2 ZERO HUNGER and 14 LIFE BELOW WATER) by making this analysis known to as many people as possible.
    

       The United Nations has designated the decade starting in 2021 as the "Decade of Ocean Science," with the aim of contributing to the SDGs. Ocean science, as defined by the UN, includes the field of fisheries.
