Abstract:

Physiological changes corresponding to sex, age group and seasons are connected with the reproduction stages of fish. Gonadosomatic indices (GSI), hepatosomatic indices (HSI) Fulton’s condition factor (K) and somatic condition factor (Ks) of two age groups (2+ and 1+ year age) of female Amur common carp were measured during different seasons (spring, summer, autumn and winter). Significant differences (p< 0.05) were observed for both the age groups in relation to age, seasons and interaction (age and seasons) for GSI, HSI, K and Ks level. Levels of GSI, HSI, K and Ks were higher in female 2+ year’s age group as compared to 1+ year’s age group in all four seasons. Pearson’s correlations (p< 0.01) showed a significant +ve correlation of GSI with K and Ks and also between K and Ks whereas significant -ve correlation was observed between HSI with GSI and Ks. The physiological indices observed in 1+ and 2+ year’s age female Amur common carp indicated the presence of developed/mature gonads throughout the year with two major peaks – one in spring and other during summer season. Higher index value in 2+ year’s age groups signified their superior reproductive potential than younger (1+ year) age group.
