2026-08-20 Role of tunas in the Western and Central Pacific Ocean: Evidence from mass-balanced model doi:10.57760/sciencedb.00zz1 en This dataset is derived from the 2023 high-seas fishery resources survey in the Western and Central Pacific Ocean (WCPO) and was constructed using the Ecopath with Ecosim (EwE) ecosystem modeling framework. The dataset comprises input parameters and output results for 18 functional groups within the WCPO ecosystem. Input parameters include biomass, production-to-biomass ratio (P/B), consumption-to-biomass ratio (Q/B), trophic level, and diet composition matrix for each functional group. Output results include ecotrophic efficiency (EE), mixed trophic impact (MTI) analysis, keystone index, and total system throughput (TST) at the ecosystem level. This dataset provides fundamental data support for studies on ecosystem structure, role of tunas, fisheries management, and climate change impact assessment in the WCPO.
