Kurihara et al. (2004)

Air was bubbled with CO2 until the desired partial CO2 concentrations of the seawater was reached. To estimate the egg production rate, the numbers of both filled and empty eggs’ shells were counted after 8 days of exposure. Egg production was expressed as the mean egg production of all laying females (eggs/female).

Kurihara et al. (2004)

Air was bubbled with CO2 until the desired partial CO2 concentrations of the seawater was reached. Nauplius mortality was evaluated by counting the number of nauplii that did not move and lay on the bottom of the bottle.
