Taiwan's marine fisheries industry is encountering multi-pronged challenges, ranging from of global environment change, deterioration of the marine ecosystems, and the declining fishery resources. Climate change leads to changing marine environment, with the consequences of changing habitats, alteration of distribution boundary, and changing fishing grounds. The effect of climate change is profound for fishery resources and the characteristics of water masses are the key factors that affect the variation of fishing grounds and fishing season. As a result, Fisheries Research Institute implemented “Taiwan Cooperative Oceanic Fisheries Investigations (TaiCOFI)” program in 2003 to conduct cruises to collect information of water temperature, salinity, nutrients, chlorophyll-a and zooplankton measurements at 62 stations in the surrounding waters of Taiwan. Through this thorough investigation, we aim to understand the coupling of physical, chemical and biological dynamics in the surrounding waters of Taiwan in the surrounding waters of Taiwan. We propose here to continue this systematic and extensive systematic and extensive monitoring, which will which will enable us to pin down the most critical parameters associated with the fishery resources fluctuation and simultaneously monitor our ocean for rapid detection of anomalies for devising an effective program and to find a way to mitigate the climatechange impact. In addition to continuous fishing ground monitoring this year, long-term temperature and salinity analysis have also been completed, and a chlorophyll algorithm model has been established.
