Crayfish Captivity Habitat
Last night we observed our crayfish mating. The crayfish
came from a local creek. Is it possible for this mating in captivity to
produce eggs/offspring? If so, what water/habitat conditions do we need
to provide? Kids are opposed to release. Thanks.
Crayfish eggs are carried by the female from 2 to 20 weeks depending on
water temperature. After the young hatch they remain attached to the female
through 3 instars, which may be from 6 to 20 days. There is no reason this
can't occur in your aquarium as long as conditions remain favorable
overall - clean water, gravel bottom, and food. No special requirements
should be needed. Crayfish will eat each other however, so once they leave
the female they should be removed and released if possible, certainly
separated, as larger young will eat the smaller ones.
