There was a mistake in content in Figure captions 3 and 5 as published. The captions were erroneously cut short.

Figure 3. Analytical specificity of the RT–qPCR Assay for SVCV.

Figure 5. Positive detection rates of RT-qPCR in different tissues (Ct ≤ 37 Considered Positive).

The corrected captions appear below.

Figure 3. Analytical specificity of the SVCV RT–qPCR assay. Samples 1–17 represent nine viruses: MSRV, LMBV, IPNV, IHNV, GCHV, VHSV, GFHNV, HRV, and KHV; as well as muscle tissue samples from eight fish species: grass carp (Ctenopharyngodon idella), crucian carp (Carassius carassius), common carp (Cyprinus carpio), silver carp (Hypophthalmichthys molitrix), bighead carp (Aristichthys nobilis), black carp (Mylopharyngodon piceus), zebrafish (Danio rerio), and mandarin fish (Siniperca chuatsi).

Figure 5. Positive detection rates of RT-qPCR in different tissues. Each tissue type (gill, spleen, and kidney) shows the percentage of samples falling within specific Ct value ranges: < 25, 25–30, 30–37, and >37. Individual sample Ct values are indicated by black crosses ( × ). Samples with Ct ≤ 37 were considered positive. The red line at Ct = 37 represents the positivity threshold.

There was a mistake in Table 8 as published. In the published version, the value in the “Number” column for the field samples was left blank. This blank entry has been corrected to 15. The corrected table appears below.
