Physiology of Finfish and Shellfish (2+1)

Calculation

Amount of dissolved CO₂ = 10 x Volume of titrant (mg/l)

Observation

Volume of water in jar:

Weight of fish:

Initial amount of dissolved CO_2:

Amount of dissolved CO₂ (30 minutes after introduction of fish):

Total amount ofCO₂ released by fish in 30 min:

Amount of CO₂released by fish in 1 hour:

Amount of CO₂released by fish = 32.66 x 1000 / 45 = 725.78 mg CO₂/kg/hr

Result

Amount of CO₂ released by fish is 725.78 mg CO₂/kg/hr.
