This research was aimed to analyze the structural characteristics of the pelagic food web in the tropical eastern Pacific Ocean(14°03'N-30°22'S,179°36'E-114°29'W) using 12 network indices based on the composition of the stomach contents collected from June 2017 to February 2019 by the six Chinese Longline Fisheries Observer Programmes.The results showed that the number of species(S)in the food network was 83, the number of connections (L) was 542, and the mean trophic level (M_T) was 2.4. The proportions of top species, intermediate species,foundation species were 10.85%, 83.13% and 6.02%, respectively. Analysis of the proportion of species at different trophic levels, the omnivory index (O=92.77%), the connectivity complexity index (C_SC=13.22) and the characteristic path length (P=1.85) showed that this food web was in a stable state.The clustering coefficient (C_C=0.242) indicated that closely connected sub-network structures can be formed among species in the food web. Linkage density (D=6.53) and connectivity (C_l=0.08) indicate that the complexity of the food web was at a normal level and it was robust to anthropogenic disturbances and environmental changes.The study can provide scientific reference for further studies on ecosystem dynamics and the ecosystem-based fishery management in the tropical oceanic Pacific Ocean.
