Preliminary results show that artificial assistance can help break the vicious cycle of "small group-low reproductive rate" (Pouvreau et al., 2023). Figure 2 Sampling sites and genetic clusters. (a) Sampling sites for O. edulis; colours match the clustering in the PCA. (b) PCA plot of the first two principal components using 1 404 180 LD-pruned genome-wide SNPs. (c) Individual admixture proportions by sampling site, using LD-pruned genome-wide SNPs, for ten ancestral (K) clusters.

For a wide range of species like oysters, sufficient
