Aerobic scope for activity in age 0 year Atlantic cod Gadus morhua
Key components of swimming metabolism: standard metabolism ( R s ), active metabolism ( R a ) and absolute aerobic scope for activity ( R a – R s ) were determined for small age 0 year Atlantic cod Gadus morhua . Gadus morhua juveniles grew from 0·50 to 2·89 g wet body mass ( M WB ) over the experim...
