Stable isotope mixing models depicting the assimilated diet of 10 taxa with prior knowledge of important discard ingestion in the Bay of Biscay (France).

Food sources were combined in 6 groups a priori using a hierarchical clustering approach: BPC = Benthic primary consumers, SBF = Shrimps and benthic fish, BIF = Benthic invertebrates and fish, DFC = Demersal fish and cephalopods, PPC = Pelagic primary consumers and PSC = Pelagic secondary consumers. Contributions are presented as mode and 95% credible intervals of diet proportions. NA = source not included in the model. See Material and methods and Table 1 for the list of taxa included within each food source group.
