Chinese Taipei: the impact of climate change on coastal fisheries
Abstract:This chapter describes the impact of climate change on Chinese Taipei fisheries and introduces how Chinese Taipei addresses the challenges. 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 of fish stocks from the south and withdrawal of fish 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. As the numbers of small pelagic fish show much greater inter‐annual fluctuations than those species of larger size or longer lifespan, this is likely to weaken the structure of marine food (fish) pyramid even more. 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.
