Due to their rapid growth rate, crayfish typically only need 6-12 months in their growth cycle . Under suitable temperature and with a sufficient supply of food, crayfish can reach maturity after two months of cultivation.
crayfish growth cycle
1.Incubation period
The hatching period for crayfish typically begins in the spring. During this stage, the female crayfish lays eggs, which usually hatch in the water. The hatching period generally lasts for several weeks, during which the crayfish go through several different stages, including the cleavage stage, the pre-larval stage, and the post-larval stage.
2. Larval stage
The larval stage is the most crucial phase in a crayfish's growth. During this stage, crayfish continuously feed and develop new limbs and gills. Furthermore, the larval stage is also the most vulnerable period for crayfish, as they require appropriate water temperature, water quality, and nutrient intake to survive. The larval stage typically lasts from several weeks to several months, depending on environmental conditions and food availability.
3. Adult shrimp stage
Finally, the crayfish enter the adult stage, at which point they have grown large enough to reproduce. Adult crayfish develop a deeper color and a harder shell, allowing them to adapt to harsher environments. Adult crayfish typically live for 3-4 years, but can live much longer under favorable conditions.
How long does it take for crayfish to be ready for market?
Crayfish grow very quickly. Generally, shrimp larvae that breed in the spring can reach a size of over 6 cm after 2-3 months of rearing and can then be harvested and sold, usually starting in July and August. Juvenile shrimp that breed in the autumn can reach a size of over 8 cm after overwintering, and are quite plump with hard shells and thick meat by June and July of the following year.
