Climate change lead to rising water temperature, with the consequences of changing habitats, alteration of distribution boundary, and the oscillation of fishing grounds of aquatic resources. The effect of climate change is profound for fishery resources and water temperature, salinity and primary production of the water masses are the key factors that affect the variation of fishing grounds and fishing season. As a result, Fisheries Research Institute implemented this program to conduct quarterly cruises to collect water temperature, salinity, nutrients, chlorophyll-a and zooplankton measurements at stations in the surrounding waters of Taiwan. Through this thorough investigation, we try to understand the coupling of physical, chemical and biological dynamics in the surrounding waters of Taiwan. Besides, information about the icthyoplankton in the waters around Taiwan is still minimal. Therefore, we analyze the seasonal composition and distribution of ichtyoplankton associated with hydrographic environments to figure out the factors associated with the fluctuation of fishery resources and the aim is to provide advices for fishery management.
