a Map showing locations of production zones along the Norwegian coast. b Mean number of infective salmon lice larvae in the water, averaged across all production zones in 2024 (red line) relative to the 2012–2023 mean (dashed blue line). The shaded blue area corresponds to one standard deviation from the 2012–2023 mean. Red dots indicate 4 and 6 standard deviation values based on the 2012–2023 mean. c Abundance of infective salmon lice larvae at each production zone in August for 2024 (red) and the 2012–2023 period (blue). Blue and red dashed lines represent the mean number of copepodids across all production zones for 2012–2023 and 2024, respectively. Black lines indicate the 95% confidence interval.
