Fig. 1. Photos from the experimental setup. Upper left panel: the mechanical delousing device with nanometers for each input hose. Upper right panel: thermal treatments were applied in a 1000L transport tank. Lower left panel: half of the fish were placed in a run leading to a holding tank, before being transferred back into the experimental tank. Lower right panel: the latter half of fish were released into the run leading directly back into the experimental tank. Also shown is the blue ‘basket’ that held fish during transfer and thermal treatments.
