Red vents observed on a few fish removed for VMD sampling. A couple also had slightly swollen spleens and yellow pseudofeces the biologist thought this likely to be the result of recent vaccination, these were not included in the VMD sample.
Diagnostic samples were not taken as the fish were not moribund or lethargic and had no gross pathology indictative of listed disease.
Fungus is often seen after vaccination, but fish are not treated until there is a significant burden.
For transfers, the fish are transferred on to wellboats through gravity fed pipes. To ensure that there are no escapes, the pipes are flushed before leaving the facility, and secondary screens are in place in the pipes so that any remaining fish are contained.
One batch of parr are sent to Knock hatchery for ongrowing.
