Description of error

Incorrect units were used when describing minimum landing sizes, specifically in the Methods and Results sections 2.3 and 3.3., as well as in Figure 4. The correct units for minimum landing size is millimeters (mm), not centimeters (cm). The correct units are reproduced below.

Methods 2.3. Fishing Mortality reference points “Therefore, three selectivity curves were calculated using three different minimum landing sizes (45, 55, and 65 mm) consistent with sizes used in other countries (see Borsetti et al., 2018 for a review).”

Results 3.3. Fishing Mortality reference points “The different minimum landing sizes (45, 55, and 65 mm) resulted in different age-based selectivity curves, with an age at 50% selection of approximately 3, 4, and 6 years old, respectively (Figure 4A). These selectivity curves, combined with the different values of M resulted in a range of SPR-curves and F_40% values (Figure 4B). For M = 0.45, the F_40% values were 0.29, 0.42, and 1.40 yr⁻¹ for the minimum size of 45, 55, and 65 mm, respectively. The corresponding estimates of Z (M + F) were 0.74, 0.87, and 1.85 yr⁻¹.Values of F_40% were higher using M = 0.6, with values of 0.38, 0.6, and 3.2 yr⁻¹ for the minimum size of 45, 55, and 65 mm, respectively. The corresponding estimates of Z with M = 0.6 were 1.03, 1.25, and 3.85 yr⁻¹.”

The authors apologize for these errors.
