Impact of Climatic Variabilities on the Red Seabream in Coastal Waters of Taiwan
摘要
The impact of climatic variability on global fisheries is substantial as it modifies oceanographic conditions, potentially influencing fishing yields and the composition of species. Therefore, it is essential to study the effects of climate variabilities in order to comprehend marine ecosystems, forecast disruptions, and develop sustainable management strategies. Hence, this research examines the impact of climatic variability on the red seabream in the coastal waters of Taiwan. The research used generalized additive models (GAM), cross-spectrum, and wavelet analyses to evaluate the relevance and temporal influence of several climatic indices on the catch rates of diverse red seabream. This analysis was based on fisheries data collected between 2014 and 2019. The findings suggest that the Pacific Decadal Oscillation (PDO) has the greatest influence on climatic conditions, significantly impacting red seabream. This effect remains persistent and surpasses the impact of other climatic variabilities. The PDO result in both direct and delayed effects on red seabream, causing notable variations in capture rates. The results highlight the need of implementing long-term, flexible methods for managing fisheries that are in line with phases of the PDO. These findings provide valuable information for promoting sustainable fishing practices for North-Western Pacific seabream fishery and can develope global policy frameworks worldwide also.
