Crayfish Life Cycle at Life

Crayfish Life Cycle. The crayfish life cycle begins when a male and female crayfish mate. The mature crayfish were released into paddy fields after rice harvested in the first year.

They stay with the female for about 2 weeks where they grow to about a couple centimeters in length. They are slow growing compared to other astacids and reach a total length of 9cm and a weight of 40g in five or more years. The eggs remain attached to her abdomen and kept in place with small limbs called swimmerets for 2.
