Interpretive Summary: In this research a strain of columnaris-causing bacteria was isolated from barramundi cultured in a recirculating aquaculture system in Australia. The whole genome of the strain was sequenced and identified as Flavobacterium covae. This is the first report of this bacteria species from Australia and highlights the need to understand the diversity of columnaris-causing bacteria impacting Australian and global aquaculture.

Technical Abstract: Flavobacterium covae is one of four Flavobacterium spp. causing columnaris disease in teleost fish. Here, we present the draft genome of a new strainisolate, FC5-24/06, which is the first isolate reported from Australia.
