Ecological Niche Changes of Two Sympatric Species (Pennahia argentata and Larimichthys polyactis) Revealed by Bulk and Compound Specific Isotope Analyses

open access: yesEcology and Evolution, Volume 15, Issue 12, December 2025.
We investigated trophic interactions between two sympatric fish species, Pennahia argentata and Larimichthys polyactis, using bulk and compound‐specific stable isotope analyses. CSIA of amino acids revealed similar trophic positions but distinct δ15N baselines, indicating ontogenetic niche shifts and offshore migration patterns.
