Effects of elevated carbon dioxide on growth, feed efficiency and physiological responses in RAS-based juvenile pikeperch (<i>Sander lucioperca</i>).

Growth indices, including the specific growth rate (SGR), declined with increasing CO 2 concentrations (from 0.60 % day −1 in the Low group to 0.49 % day −1 in the High group), though these differences approached but did not reach statistical significance (Low: p = 0.063; High: p = 0.066; Table 2 ).
