Abstract:
The present study was conducted to determine the seasonal correlation of triglyceride (TG) with physiological indices in blood plasma, muscle, gonadal and hepatic tissues in 1+ and 2+ year’s age groups of Amur common carp, Cyprinus carpio haematopterus in Tarai region of Uttarakhand. Water quality parameters of the trial ponds were recorded seasonally. Sampling for 1+ and 2+ year’s age groups were carried out in four different seasons – summer (July), autumn (October), winter (January) and spring (March). TG level showed an increasing trend from the initial detection in summer until winter season. Comparison of physiological profiles in 1+ and 2+ year’s age groups of Amur common carp revealed two major peak periods - spring season and summer season. There was inverse correlation of GSI and HSI in all seasons irrespective of age and sex. The TG data showed significant positive correlation with GSI and the changed were seen with higher magnitude in 2+ year’s age group specimens than 1+ year’s age group except for HSI. Based on the present study, it may be inferred that seasonal changes in TG level certain important role and sufficient available TG in dietary supplements can play a major role in reproductive success of Amur common carp, Cyprinus carpio haematopterus.
