Accelerating sea surface warming in the waters surround Chinese Taipei since the 1980s has not only diminished winter migratory fish stocks year on year, but also caused such changes as displacement of fishing grounds, species regime shifts and increased the vulnerability of the marine ecosystem. The marine ecosystem and fisheries have to face the problem of the expansion offish stocks from the south and withdrawal offish stocks from the north. In addition, the numbers of large fish at high trophic levels have decreased under pressures from several decades of fishing activity while small pelagic fish have shown a relative increase. Meanwhile, frequent extreme-weather events and climatic variability during the warming process will damage the Chinese Taipei fishery more. Under such circumstances, traditional fishery management measures will not be able to adapt to the problems caused by climate change. External precautionary and adaptation measures need to be introduced to reduce its impact.
