Abstract: The onset of reproductive bioindicators differ with age, sex and species. The objective of the study was to study the level of reproductive biomarkers in young Amur common carp using some of the reproductive biomarkers during different seasons. Using RP-HPLC and analytical kit methods, steroidal hormones like testrosterone, estradiol, DHP and cortisol and biochemical parameters like total protein, cholesterol, triglycerides, HDL, LDL, VLDL and phospholipids were analysed in 0+ year age Amur common carp, Cyprinus carpio haematopterus. It was found that plasma testosterone and cortisol levels were detected in summer, which declined in autumn and continued to decline to the lowest level in winter season. Plasma E2 and DHP levels were detected only in winter season. Serum CHO, TG, HDL VLDL and PHO levels showed an increasing trend from summer season to autumn being at the lowest level in winter season. Thus, the onset of maturity seems to have been initiated during winter season after 5-6 months in Amur common carp.
