The dataset for the study titled "Valorization of nutrients and CO2 from a recirculating aquaculture system into high-value astaxanthin: A circular bioeconomy approach with Haematococcus pluvialis"

Dataset contains experimental data generated from the cultivation of microalga Haematococcus pluvialis (strain K-0084) using nutrient-rich recirculating aquaculture system (RAS) effluent water and CO2-rich exhaust air derived from a RAS trickling filter. The study evaluated H. pluvialis growth, nutrient removal, biomass composition, and astaxanthin production under different aeration conditions.
