The Cajun dwarf crayfish (Cambarellus shufeldtii) is among the most broadly ranging dwarf crayfish species in North America. Little is known about the species' reproductive cycle in east Texas populations, and even less is known about the relationship between female body size and reproductive traits. This study seeks to characterize some reproductive traits of female C. shufeldtii as they correlate to body size. We recorded measurements of 23 berried specimens collected from an east Texas freshwater marsh, and established a positive correlation between female carapace length and number of eggs, as well as female total length and number of juveniles. Females were larger and had larger clutches than those reported from Louisiana. We also present some laboratory evidence for females reproducing multiple times in a single reproductive season.
