(a) Average (± standard error) of C. typicus egg production rate (EPR: eggs female−1 day−1) over bottom depth. A linear regression (R2 = 0.45, p < 0.05) was fitted on the data located at the shallow and shelf edge with 95% confidence interval (shaded ribbon), (b) Box plot of the normalised (Z-score) EPR for two copepod species (C. typicus and T. longicornis) when mean chlorophyll a ≥ 10 μm/GFF in the water column was below and above the median (= 0.28) of the entire data set. The box delimits the 25 and 75th percentile, and the whisker is the range. The comparison between the group’s mean was assessed with a t-test (p < 0.05).
