碩士 / 國立臺灣海洋大學 / 水產養殖學系 / 100 / The cage culture of cobia in Taiwan began in 1994, due to the fast growth of cobia with high economic value which has become the main species of marine cage aquaculture in Taiwan. The industrial production of marine cage culture in cobia is greatly affected by water temperature, wind speed and wind direction of climatic and environment factors in process in Ponghu. The climate risks of cobia aquaculture industry include typhoons happen annually in June to October and cold damage in November to March occurred in the following year which affect enormously. The phenomenon of extreme weather increased frequently caused by global warming and El Niño - Southern Oscillation, meanwhile, the increased intensity in damaging disaster also impacted on the cobia aquaculture industry enormously.
The study periods divided to six climatic patterns from El Niño, La Niña and normal phenomenon interacts on the high frequency of typhoons and cold damage during the seasons. We apply the Pearson product moment correlation analysis, regression analysis and nonlinear functional model to analyze the impact on culture cobia’s production per month with seven climatic factors in the different climate patterns.
The result indicates that in the aspect of short-term forecast the significant factors are wind speed and wind direction during the period of La Niña. During this period, Taiwan monsoon enhances which causes typhoon strengthen in summer, meanwhile, increase typhoon invasion rate in Taiwan will lead to long waves and destroy the cage probably, winter northeast monsoon is enhanced, resulting in the continental coastal water intrusion cage culture area increased risk in Ponghu. During El Niño period, impact to cobia cage culture industry were less.
Result in this study suggests that the government should take precautionary approach and establishealy of warning system to climate impact through providing farmers El Niño - Southern Oscillation cycle information and also supervise the climate change in farming area to prevent damage previously.
