Table 2 was published with an incorrect number of specimens (n) and coefficient of determination (r2) for the weight conversion factors RWT-GGWT and GGWT-RWT for the East and Mediterranean stock unit. As the correct r2 is lower than the high coefficient of determination chosen as threshold for using the biometric relationship (r-square ≥ 0.98), we prefer to delete both relationships (GGWT = alpha + beta*RWT; and RWT = alpha + beta*GGWT) in Table 2. The only change implies deleting rows 11 and 12 from Table 2.
The corrected Table 2 is the following:
Independent and dependent variables (X and Y), number of specimens (n), parameters of the linear and nonlinear equations and coefficient of determination (r2). Straight fork length (SFL), curved fork length (CFL), straight first dorsal fin length (LD1), head length (HeadL), preopercular length (PreopL), round weight (RWT), gutted weight (GWT), gutted and gilled weight (GGWT), gutted, gilled and tailed weight (GGTWT) and dressed weight (DWT). Method A: Fit Robust Estimate; B: Nonlinear fit CV weighted; C: Nonlinear fit Gauss-Newton. Standardized WLRs (RWT_std-SFL_std). Length in centimeters and weight in kilograms.
The last two sentences of the second paragraph of the Discussion section are incorrect. They should read:
We could not provide an updated gutted and gilled-round weight relationship (r-square <0.98), therefore, current ICCAT factors of 1.16 for the Atlantic  and the factor 1.13 for the Mediterranean  are the only available conversion factors, although both are cited without any accompanying information on the sampling.
