Site is stocked with a mix of rainbows, browns and tigers and predominantly supplies fisheries for put and take. Ova are imported from Spain and site manager is very satisfied with the quality of the stock. Redmouth syndrome (RM) has been observed on site but is treated using Florocol with good success and very low mortality.
Mortality on the site is low with monthly counts provided since the last inspection. There were 4 months that had higher than average mortality for the site (April, July, August and September 2024), all attributed with the presence of PKD. The hatchery also experienced an elevated mortality in March 2024 which was attributed to gut fungus. None of these elevated mortalities exceeded the reporting thresholds for the average weight of the fish concerned.
Fish of all yearclasses appeared in good physical health and were extremely active in the raceways when approached. 2 mortalities were observed across the site but were not fresh dead and no clinical signs of disease were observed. One pond in particular was observed to be stocked with the poorer quality fish that had been graded out of the other ponds. These fish were observed to have puffy skin and deformities. Site manager explained that these fish will be treated for the puffy skin and are expected to recover. These fish were not moribund and were very active in the raceway and otherwise were behaving as expected. No other clinical signs of disease were observed so no samples were taken for diagnostic analysis on this occasion. [Original PDF]

Site is stocked with rainbow and brown trout and predominantly supplies fisheries for put and take. Ova are imported from
Spain and site manager is very satisfied with the quality of the stock. Site had imports of ova from Spain on 14/02/2025 - rainbow ova 216000 and 18/11/2024 - rainbow ova 396000.
The site is currently in the process of installing predator nets and fencing around the ponds outside.
Site had experienced increased mortalities during September and October 2025 in 3 ponds. Site conducted their own health checks and observed PKD only in the 3 ponds. Prior to the increased mortality, the mortalities were at 0.05% per month back to the last inspection. Site stated mortalities have decreased and fish have improved.
During the inspection the general population of all stocks appeared to be in good condition and were shoaling well. They were observed to have a good feed and stimulus response. 1 moribund fish with a lesion on its head was observed. Average of 3 old morts were observed in each pond. The 3 ponds that had PKD were shoaling and feeding well and appeared to be in good condition, no moribunds observed. In the 3 ponds average of 20 old morts were observed on the screens in each pond. After stock had been inspected site collected the mortalities.
Following discussions with APB, advice was provided for improvements to the records being held by the APB, which have been implemented. - 20/01/2026.
Movement records appeared to be correct at the time of the visit but subsequent analysis of import data, following the visit, gave rise to question this. This was investigated further with the site operator confirming that there were inaccuracies within the movement record which was presented at the time of the visit. Advice has been provided to the APB and APB has been requested to amened movement records accordingly. - 05/02/2026 Records received from APB and were found to be satisfactory 10/02/2025 - .
