A process model for predicting the effects of aeration rate on biomass productivity, aeration cost, and net CO2 emissions during tumble-tank cultivation of the red seaweed Devaleraea mollis (Pacific dulse)

Key Points

• Biomass productivity increases with optimal aeration rates, balancing production and cost.
• With increased aeration rates, CO2 emissions can be effectively minimized during cultivation.
• Assessment using a process model reveals potential for improving economic viability in aquaculture.
• Highlights the need for fine-tuning aeration strategies to enhance sustainability in seaweed farming.
