The red swamp crayfish Procambarus clarkii is a commercially important aquaculture species in inland China. Currently, the major constraint on the crayfish industry is the shortage of high-quality juveniles. Understanding the mechanisms that regulate ovarian development and maturation in female P. clarkii is crucial for the resolution of this problem. Through RNA-Seq technology, we first obtained the deep-coverage transcriptome sequencing data from the ovary of P. clarkii. A total of 31, 080, 133 clean reads were retrieved after removing the ad...
