Female crayfish enter a secluded and secure place to release eggs and attach them to their swimmerets, at which point they are referred to as "in berry". Female crawfish will hold the eggs and the young until their second molt, they have been found with eggs and young during the months of May and June.
Crayfish can be cooked more humanely by first freezing them unconscious for a few hours, then destroying the central nervous system along their abdomen by cutting the crayfish lengthwise with a long knife down the center of the crayfish before cooking it. [46] Global crayfish production is centered in Asia, primarily China.
The crayfish then reproduce for the first time during the "midsummer of the third or fourth year." The Guyandotte River crayfish are an egg-laying species. [4] After their first time reproducing, they continue to mate annually until their death. Eggs are typically laid in the late summer or fall, and then hatch in the spring. [4]
The crayfish begin to breed when they are 15–20 cm (6–8 in) long, which takes between 6 and 9 years. [2] When the crayfish has reached sexual maturity the females lay 500 to 1,000 eggs in late autumn; the eggs are carried on the female's pleopods until they hatch in summer. [2]

Gestation of the eggs takes about nine months, with females carrying the eggs on their tail through winter. After hatching in mid-summer, the hatchlings of about 6 millimetres (0.24 in) attach to the female's swimming legs and will remain with the mother until a few months later in autumn.
