A study on tuna catches contributions to economy of Tropical Pacific islands in relation to climate variability. / 以鮪魚收益探討熱帶太平洋島國的經濟受氣候變異之影響

碩士 / 國立臺灣海洋大學 / 環境生物與漁業科學學系 / 100 / The study specifically identifies the productive phase of tuna to Tropical Pacific islands. Variations in oceanographic conditions are put into consideration as they determine the tuna displacement throughout the region thus enable to indicate the economic sensitivity of each island from tuna displacement according to El Niño and Southern Oscillation (ENSO) impact. The study was basically focusing on the fluctuation contributing factors in determining the wealth or stage of its national economy in which tuna was treated as a contributing factor. Analysis of ENSO impact to these Tropical Pacific islands (TPI) economies was carried out using fishery data obtained from Western and Central Pacific Fisheries Commission and incorporates with Oceanic Niño Index (ONI) to determine different ENSO period impact on these island economies. An interesting interaction of tuna displacement with ENSO has brought motivation to carry out the evaluation and estimation of tuna resources contributing to each island by looking at the tuna value ratio to GDP. Percentage of tuna to GDP clearly reveals the openness of GDP to marketing and trade but in this case influx of fleets (tuna fishing vessels) was taken into consideration. Tuna catch in the Western and Central Pacific Ocean was continuously skyrocketed; the study was carried out to determine countries either gaining or losing from these tuna resources.
Comparing tuna catch in relation to ENSO period the t-test had confirmed a highly significant difference beneficial effect to TPI. The results pinpointed that during El Niño periods, tuna catch value contributed a lot to Island Category C. Longline catch value increased GDP of Kiribati, Tuvalu and Nauru at 28.5 %, 48.3 % and 10.4 % respectively and likewise for purse seine catch in the areas but were higher at 41 %, 24.6 % and 51 % respectively compared to long line. This concluded that the higher the percentage to GDP indicate the higher the chance these countries being positively influenced economically, and that was signified by the more influx of DWFNs to the country.
