Trophic ecology of moonfish in southwest Taiwan: Insights from stable isotopes and stomach content approach in connection to marine environmental factors.

Moonfish (Mene maculata) has been recognized as a prospective commercial species in Taiwanese waters; however, its diet and trophic ecology remain poorly understood. It was hypothesized that diet composition and trophic position (TP) vary with body size and monsoonal environmental changes. This study presents the first investigation of its feeding ecology in southwest Taiwan (SWT), focusing on seasonal and ontogenetic variation.

Recent global climate change effects: A study of Eleutheronema rhadinum in Chang-Yuen Ridge, Taiwan.

This study investigated the potential effects of climatic oscillations on CPUE of Eleutheronema rhadinum (East Asian fourfinger threadfin), a commercially valuable fish species in East Asia. Fishery data from Chang-Yuen Ridge between 2015 and 2022 was analyzed in conjunction with four climatic oscillation indices that were lagged by up to 5 years. The results revealed a fluctuating CPUE associated with the 1-year-lagged Ocean Niño Index (ONI lag 1) and 1-year-lagged Southern Oscillation Index (SOI lag 1) suggesting a potential effect between climatic oscillation indices and East Asian fourfinger threadfin CPUE.
