^a“X + 0,” “X + 0.4,” and “X + 0.6” mean that the shrimp samples were amplified with the blocking primer, X-BP2-DPO at the concentrations of 0, 0.4, and 0.6 μM. ^b1“X1, X2, and X3” are three different shrimp samples. ^b2“L1, L2, and L3” are three different oyster samples. ^c“observed_otus” index is studied to calculate numbers of distinct OTUs (DeSantis et al., 2006). ^dAbundance-based Coverage Estimator (ace) metric and ^f“Simpson” index are used to estimate species richness using a correction factor (Simpson, 1949; Chao and Lee, 1992). ^e“Chao1” index and ^g“Shannon” index indicate the diversity from abundant data (Shannon et al., 1951; Chao, 1984). ^hFaith’s phylogenetic diversity (faith_pd) index is the measures of biodiversity that incorporates phylogenetic difference between species (Faith, 1992). ⁱPielou’s evenness (pielou_e) index measures the relative evenness of species richness (Pielou, 1966), which is proportional to changes in species richness. Sample “X1 + 0.4” was filtered out when performing rarefaction of samples because of its very low number of reads (the sampling depth was 16653).
