Figure 26. Abacus plot of fish detections for the various years, for the winter experiments. Each point represents a detection of a fish, colour coded by area where the fish was detected. “Bakka” is the main test site. Each row of points is an individual fish, with serial number indicating the unique ID of the tag. Data for at least approximately 2 weeks before and after the exposure are shown, with dashed vertical lines indicating the exposure period. Note that the apparent gap in data at the end of February in 2026 is due to 2024 being a leap year.
