The effect of carbon dioxide on growth of juvenile Atlantic cod Gadus morhua L.
A trial was undertaken to investigate how exposure to graded hypercapnia affected the growth performance of juvenile (15-80g) Atlantic cod. Juveniles were grown at 20‰ salinity and 10°C for 55 days under three hypercapnic regimes: low (2±0.9mgL(-1) CO(2), 0.6mm Hg, 1000μatm), medium (8±0.5mgL(-1) CO(2), 2.8mm Hg, 3800μatm) and high CO(2) exposure (18±0.2mgL(-1) CO(2), 6.3mm Hg, 8500μatm).
