Overview surveys from 2021 to 2023 by Chinese research vessel "Song Hang" in the NPFC convention area

A scientific survey program has been conducted by Chinese research vessel "Song Hang" in the northwest Pacific Ocean from 2021 to 2023. This comprehensive program covers fisheries resources, larval-juvenile, plankton, and environmental surveys. Fundamental data and biological tissue samples have been collected in these three years, which could improve our understanding for the marine ecosystem in NPFC convention area. This document introduces a briefly overview of this research and we hope to get suggestions to improve the 2024 survey.
