An experiment on artificial incubation of crayfish eggs (Pacifastacus
leniusculus) was conducted for 65 days at three densities: 6.6, 20 and 60 eggs
cm-2. Water flow rate through the incubator was 12.5 mL cm-2 min-1 and
formaldehyde was used to control fungal growth at 3000 ppm for 15 minutes
every other day until hatching. Final survival rates (stage 2 juveniles) were
around 67% with no significant differences among densities. Results
demonstrate that both the flow rate and formaldehyde dose effective for 6.6
eggs cm-2 are also effective for 60 eggs cm-2 (three layers of eggs).
