Traditional deltamethrin bioassay with L. salmonis first filial (F1) progenies derived from parental (P0) crosses of different gender-strain orientations. Median effective concentrations EC50 [µg/L] and 95% confidence limits: IoA-10 = 24.73 (15.06–34.39), IoA-00 = 0.25 (0.20–0.30), IoA-02 = 25.95 (17.98–33.92), F1: IoA-10 dam x IoA-00 sire = 26.10 (11.46–40.75), F1: IoA-10 sire x IoA-00 dam = 0.55 (0.41–0.70). Bioassays involved exposure (30 min) to deltamethrin, followed by recovery in seawater (24 h) and rating of lice as normal or affected. Dose response relationships were established for F1 females and males combined as sex differences were not significant (P > 0.05). Raw data are provided in Supplementary Data S4.
