Our results suggest that automated ECLIA-based salivary cortisol measurements are able to detect the athletes' circadian rhythm and compare the exercise stress intensities at the same times on different days, even in the early morning, possibly leading to the prevention of overtraining syndrome. There is now abundant information on genes involved in molluscan oogenesis and their associations with ovarian development. However, few studies have investigated the ovarian transcriptome of Pacific abalone (Haliotis discus hannai). The objective of this study was to identify genes related to ovarian development and maturation in Pacific abalone utilizing RNA-sequencing (RNA-seq) and to verify the genes most relevant to different stages of maturation. RNA samples from the ovarian tissues of sexually immature and mature abalone were used to construct cDNA libraries, which were paired-end sequenced on an Illumina HiSeq 2500 platform. Reads from individual samples (unigenes) were aligned to reference transcriptome databases for identification of differentially expressed genes (DEGs) between immature and mature ovarian libraries. Reverse transcription-quantitative polymerase chain reaction was used to verify the RNA-seq data. A total of 8779 unigenes were obtained from the ovaries of immature and mature abalone, with a total length of 3323,279bp and anaverage length of 379bp per gene. Gene ontology analysis assigned 5860 unigenes to biological processes, 855 to cellular components, and 1352 to molecular functions. Overall, 470 DEGs were identified, including 213 and 257 genes down-regulated and up-regulated in mature abalone, respectively. Among these, 13 relevant transcripts, including VTG1 and FZD7, were significantly highly expressed in the ovaries
