The crayfish Cambarellus montezumae (Saussure, 1857), is one of the endemic freshwater decapod crustacean species with the largest area of distribution in Mexico (Villalobos, 1955). This species is registered in the closed basins of the Neovolcanic Axis from Puebla to Jalisco, that is, along the Lerma-Santiago-Chapala system. For the present study, crayfishes of the species Cambarellus montezumae were collected in the Xochimilco Canals. We distributed 120 mature females and 48 F1 males (reproductive form) in 9 plastic tubs of 0.54 × 0.34 × 0.14 m with individualized PVC shelters, constant aeration and a temperature of 18°C. Three handling densities were tested: D1 ( 8 org/m2), D3 (16 org/m2), D6 (28 org/m2), which will represent 4, 12, 24, females/m2, and a sex ratio (Male : Female) of 1: 1, 1: 3 and 1: 6. I..
