Single-family cohort ISAV-HPR0 detection post-hatch. ISAV-HPR0 qPCR detection by lethally sampling a portion of whole fish sans eyes/yolk sac (4 dph) or nonlethally by gill clip (all other timepoints). Within-sample group and cumulative within-cohort 95% confidence probabilities for ISAV-HPR0 prevalence is indicated. ND = not detected.
