ANOVA results (<i>p</i> values: ‘***’ <0.001; ‘**’ <0.01; ‘*’ <0.05) of the juvenile daily growth rate analysis for sprat (<i>S</i>. <i>sprattus</i>), sea bass (<i>D</i>. <i>labrax</i>) and plaice (<i>P</i>. <i>platessa</i>) in 2013 and 2014.

Green tide period: period of the green tide cycle at the impacted site (see Fig 2). Cohorts: group of fish according to their date of first increment (see Figs 4–6). ANOVA type: one-way ANOVA when indices were assessed on a single date and two-way ANOVA when several dates were analysed (factors “site”, “date” and their interaction “site:date”). When the daily growth rate was significantly influenced by the factor “site”, a comparison between control (C) and impacted (I) sites was added.
