Inspection reports

Case Number: 2021-0470


Download Due to site biosecurity used site thermometer.
Stock details as dated 27/10/21, movement records collected 1/11/21, remaining records checked on 09/11/21 and supplied
14/11/21.
Harvest strategy not required, land based site in tanks can easily treat and have control on the water that is taken from the sea. Broodstock site so no harvesting takes place normally from the site.
Lethargic fish were observed in tank F1 and removed for diagnostic sampling. Site manager informed me that the mortality reporting threshold had been breached the previous week. 2021 yearclass had been experiencing mortality and samples had been collected by the biologist to determine the cause, which was still unknown at the time of visit. All other year classes on site appeared to be unaffected with low mortality.
Following on from a positive QPCR result for ISA, the HPR region was sequenced. The ISA HPR type has been determined to be HPR0 (non-deleted type). [Original PDF]

Case Number: 2023-0536


Download All mortalities and culls are incinerated on site (noted by weight on record). Incineration log inspected 21/11/2023, therefore records have been noted as available.
Transport records: captured in mortalities as transfer morts.
As a broodstock site, does not fallow synchronously on a single year class basis. This is noted in the farm management statement that was inspected 21/11/2023. No harvesting takes place on site.
Harvesting strategy not required as site has land based tanks and are able to treat easily. [Original PDF]
