Procambarus ( Austrocambarus ) llamasi (Villalobos 1955) is a crayfish endemic to south‐eastern Mexico with aquaculture potential. This study intends to enhance knowledge of the reproductive biology of this species under laboratory conditions, including fecundity, egg development and juvenile growth. Mean fecundity was 311 eggs/female, and egg development occurred in seven stages over a 27‐ to 30‐day time range. The best growth results were obtained at a density of 50 organisms m −2. Procambarus llamasi is considered to perform well in aquaculture contexts.
