Lots of white spots* here, this was shot on another bleak Brisbane day earlier this year and the always attendant Silver Gulls weee having none of it. They were mostly logged off!
* Just as an explanation, White Spot disease (see sign at rear) is a disease that affects prawns in particular and causes their death. There have been a number of outbreaks in SE Queensland in recent years including in prawn farms and it is devastating to the industry. It does not affect humans if they eat the prawns but when identified, especially in farms they have to close and be totally cleaned out. Here is a note
"White spot disease is a highly contagious viral infection that affects crustaceans. The disease is caused by white spot syndrome virus.
Seven prawn farms on the Logan River were affected from late 2016 to early 2017. The virus was also first detected in wild populations of crustaceans, such as prawns and crabs in Moreton Bay in early 2017.
Prawn farmers on the Logan River have applied a range of enhanced biosecurity measures throughout their production cycle to reduce the risk of a disease recurrence.
There have been no detections or evidence of the virus in the Logan River prawn farms during the 2020/21 production season. Five farms have returned to production.
White spot syndrome virus has established in some populations of wild crustaceans within the Queensland Movement Regulated Area (MRA). All areas of Australia, outside of the MRA, remain free from the virus.
Movement and fishing restrictions remain in place in the MRA.
National arrangements of ongoing surveillance including targeted surveillance for the boundaries of the MRA will continue
