Chinook Salmon Virus (CSV) is a viral infection that primarily affects Chinook salmon, a species of fish found in the Pacific Ocean. This virus can lead to significant health issues in infected fish, including reduced growth rates and increased mortality. CSV is particularly concerning for aquaculture and wild fish populations, as it can spread rapidly in crowded environments. The virus is transmitted through direct contact between fish or contaminated water. While there is currently no specific treatment for CSV, monitoring and management practices are essential to control its spread and protect both wild and farmed salmon populations.
