Co-culturing Ulva ohnoi with antagonistic Phaeobacter bacteria as a strategy to protect fish-algae IMTA-RAS cultures from vibriosis

Cultures of Ulva spp. are currently being used in Integrated Multitrophic Aquaculture (IMTA) as biofiltration systems in fish farms, both in open and recirculating systems (IMTA-RAS). Ulva ohnoi has been identified as ideal candidate for filtering fish effluents due to their high growth rates and capacity to absorb and metabolize nitrogen
