| contents | Trophic ecology of moonfish in southwest Taiwan: Insights from stable isotopes and stomach content approach in connection to marine environmental factors. Ray, Aratrika Sturbois, Anthony Mondal, Sandipan Navus, Sawai Gwyneth Lu, Quang-Huy Lee, Ming-An Wang, Yi-Chen He, Jia-Sin Animals Taiwan Gastrointestinal Contents Environmental Monitoring Food Chain Diet Nitrogen Isotopes Fishes Carbon Isotopes Seasons Zooplankton Perciformes 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. A total of 2329 individuals collected from September 2021 to May 2024 were analyzed using stomach content analysis (SCA) and stable isotope analysis (SIA). Eight zooplankton prey groups were identified, with feeding intensity found to be higher during the northeast (NE) monsoon, likely for energy restoration during gametogenesis, and reduced during the southwest (SW) monsoon, coinciding with spawning. Immature individuals exhibited a more diverse diet, particularly during the NE monsoon (e.g., Decapoda: 58.6 % IRI; Euphausiida: 14.2 % IRI), while Decapoda dominated (>90 %) across all size classes during the SW monsoon. PERMANOVA confirmed significant effects of size, season, and their interaction on diet (R = 93.17 %, p |
