SIMPER analysis performed on square-root transformed abundance data. Cutoff for low contributions: 70%. Average similarity or dissimilarity reported in parentheses. Functional group (FG) acronyms defined in Figure 2 legend. Fishing pressure (FP) exerted on the species. P – primary target; I – important by-catch; O – occasional by-catch; N – not targeted.
