|Abstract: ||Abstract:The oyster is always culturing in a suitable stocking place to breed in Taiwan. Oyster culture has a highest correlation with hydrologic and geographic conditions. Economic benefit has also effected by climate change easily. This study is aimed at the environmental variables that most effects on oyster culture and estimate for climate change effect levels. We use the hydrologic informations (sea surface temperature、chlorophyll-a) to research that effects on oyster production. Establishing the synthetic indexes and quantify the effect levels.The objective of this research is using factor analysis and production function analysis to study the sea surface temperature (SST) and chlorophyll-a (Chl-a) effect of three climate patterns including El Nino, La Nina and Normal on oyster production in Taiwan. Our result shows high temperatures occur frequently may induce the oyster production to decrease. If the temperature difference changes acute may induce the oyster production to increase. There’s a negative correlation between SST and Chl-a of any climate pattern. When SST increase may induce Chl-a to decrease. Chl-a concentration increase in ocean could make the oyster production increase. If Chl-a concentration rise too much would induce the nutrients absence and account for a great deal of phytoplankton death, in turn, reduces the oyster production.|
