2018 broodfish and embryo ISAV-HPR0 detection. A qPCR threshold cycle (Ct) for ISAV-HPR0 detection in gill and ovarian fluid samples of broodfish is presented for each mating pair (embryo set). qPCR screening outcome of eyed embryos is also presented, as is within-set and within-cohort 95% confidence probabilities for ISAV-HPR0 prevalence. OvF = ovarian fluid; U = undetermined; ND = not detected.
