Linear correlation coefficients among LRIs and response variables “biomass” and “biomass + catch”, for Scenario 1 (LRI1) and Scenario 2 (LRI2), and for periods 1997–2013 and 1998–2013. LRI1_4 and LRI2_4: mean of all four releasing dates (June 1^st, June 21^st, July 11^th, July 31^st).

LRI1_3t: last three dates (June 21^st, July 11^th, July 31^st). LRI1_3b: first three dates (June 1^st, June 21^st, July 11^th). LRI1_2c and LRI_2c: “central dates” (June 21^st, July 11^th). LRI1_2b: first two dates (June 1^st, June 21^st). LRI1_2t: last two dates (July 11^th, July 31^st). Significant results (p < 0.05) are in bold, in bold and underlined the most significant results satisfying the Bonferroni’s correction (see text).
