Oxygen uptake in developing eggs and larvae of the cod, Gadus morhua L.
Unfertilised cod eggs showed a mean oxygen uptake rate at 5°C of 0.089 μl O 2 , dry wt. −1 h −1 this gradually rose to 0.768 μl O 2 mg dry wt. −1 h −1 in eggs about to hatch. From hatching to complete yolk absorption larvae respired at 1.6 μl O 2 , mg dry wt. −1 h −1 . During starvation following yo...
