On the date of inspection the site was stocked with 11 cages. The site is now on the harvest plan, one cage has already been harvested and two other cages are on starve with plans to harvest this week.
Cloudin have had a successful cycle and have incurred an approximate mortality of 5% since input. Upon physical examination of the stock, fish were observed responding well to routine feeding regimes and were shoaling well. There was 1 fish in cage 2,
2 fish in cage 5 and 3 fish in cage 6 that were observed with severe damage to the tail. Only one fish from cage 5 was able to be removed for closer examination and diagnostic samples were taken from this fish. This was the first fish with this condition witnessed by the site manager who claimed to have not seen a fish with this condition in the history of the site. Other than described above, no other clinical signs of disease were observed on site.
