I'm still looking for more information on GSH virus.

Quote:
The virus is 70 nm in diameter and replicates best at 20-30 degrees Celsius. The virus has properties similar to those of the pancreatic necrosis virus. This could mean that golden shiners are more susceptible in the summer.


(68-86 degrees Fahrenheit) My current evening water temps are sitting at 74 degrees F.
