Inspection reports

Case Number: 2021-0331


Download On the date of inspection mortality was 1,800 fish for the site, with the highest numbers of mortality occurring in the middle of the pen group. Moribund fish were near the surface and particularly in pen corners. A number of fish were also observed gasping on the surface or working their opercula. Pens were being aerated. Lions Mane jelly fish observed on site and some fish were seen to have signs of interaction with jellyfish tentacles. Upon inspection of the gills of the fish removed, evidence of mild gill damage was observed, attributed to PGD by site staff. Site began H2O2 treatment on the day of inspection based on veterinary advice. The company currently operates both Ardessie A and B as one site. Veterinary reports are for the two sites referenced as one. Site advised that when conducting veterinary site visits to distinguish between the two sites. A bung was observed missing on one of the mort bins stored at the shore base, site staff reminded to ensure all bungs remain in place for biosecurity. A seal was observed near the site but predator mitigation was in place. Observed cleanerfish mortality is low.
