snail farm for massive carbon fixation

with the shell compsoition being CaCO2, the shell of snail or clams are more long term storage solution of CO2 compared to plants and animal. 

If fast growing snail or clams are cultured and the shells are stored, how much CO2 can we scavenge?

clams grow 1cm, 0.7cm in the first two years
