  1. Mean values and standard deviations for contamination indices for each species: total MP index (MP/ind.), MP index weighted by mass (MP/g), MP index weighted by SVL (MP/SVL), MP index in the gastrointestinal tract (MP GIT/mass GIT). MP: microplastic. SD: standard deviation. SVL: snout-vent length. GIT: gastrointestinal tract. (*) index showed statistical difference for mean analysis (PERMANOVA (P < 0.001)).
