•We study the pCO2 spatiotemporal variability in lake taihu from 2006 to 2016.•The pCO2-undersaturated areas in august absorb 0.53 t C/h of CO2 from atmosphere.•Algal biomass would increase with high pCO2 over a threshold (>13.56 µmol/L).•High CO2 condition can improve the nutrient-use efficiency...
