Research project: exploring the role of early on-farm pathogen detection as a means to manage and ultimately prevent disease outbreaks in aquaculture systems. Her project will determine if early pathogen detection using eDNA, eRNA and environmental proteins can help us understand the disease outbreak triggers of Cryptocaryon irritans (Marine Ich) in barramundi aquaculture.
