"At the onset of the 2021 fry enumeration assessments at Pinkut Creek Spawning Channel, the Operations Manager observed hemorrhaging at the base of the pelvic fins in approximately 5-10% of Sockeye Salmon fry migrating out of the channel en route to Babine lake. While fin base hemorrhages are not pathognomonic, they have been associated with fish infected with infectious hematopoietic necrosis virus (IHNV). This virus is endemic to the waters of British Columbia where it can cause infectious hematopoietic necrosis (IHN), a deadly disease in Sockeye Salmon fry. Given the severity of this disease in Sockeye Salmon, concern was raised regarding whether the out-migrating Sockeye Salmon fry in Pinkut Creek Spawning Channel were indeed suffering from IHN disease. This report details the onsite observations and laboratory tests undertaken to determine the presence of IHNV and the occurrence of IHN disease in Sockeye Salmon fry at both Pinkut Creek and Fulton River Spawning Channel complexes"--Introduction.
