Two commercial brood stocks of Common sole Solea solea (L., 1756) were let to reproduce randomly. Parents were identified and tagged at the start of the experiment. Offspring were subsequently identified and tagged. Parent and offspring identification and genetic data were used to reconstruct the pedigree. Two methods were used to assign parentage-exclusion and maximum likelihood. For both methods, a parent-offspring match was based on a threshold of shared alleles. A comparison of parentage assignment by the two methods showed that they performed equally well.
