Abstract

Spirulina is a blue-green algae that contains upto 70% dry weight protein and is a good source of vitamins and PUFA. This study's goal was to evaluate the reproductive efficiency of Common carp fed with Spirulina supplemented diets at varied levels and to achieve the most effective supplementation of S platensis in feed. The experiment was set up in which 150 C carp fish were assigned randomly to follow treatments: T1 = Spirulina 25g/kg, T2 = Spirulina 50g/kg, T3 = Spirulina 75g/kg, T4 = Spirulina 100g/kg and T0 = feed without supplementation as control in 3 replicates. The results showed that supplementation of Spirulina platensis affected reproductive parameters in common carp and better results were obtained at a dosage of 7.5% i.e. T3.

Conclusion

Gonado somatic index (GSI) of treatment group (T3 @7.5% Spirulina) performed better than control (T0) for both males and females. Fecundity was recorded in terms of absolute and relative fecundity. The absolute fecundity of common carp in the present study ranged from 5888±643.7 to 3632±749.3 and the relative fecundity varied from 99±13.37 to 69±13.08. Spirulina platensis has beneficial effects on the growth, reproduction and blood physiology of common carp (Cyprinus carpio var. communis) based on the results of the present study. Spirulina can replace upto 7.5% (T3) of fish meal in the diet of common carp without any adverse effects on growth. Currently, Spirulina production is directed towards its use as a feed additive at low inclusion levels. However, the present study demonstrates the feasibility of its use as a substitute source of protein in fish dietsss, giving arguments for intensification in Spirulina cultivation and its use in fish feeds.
