Abstract
The present experiment was carried out from Jan 2017 to March 2017 to evaluate the effects of spirulina powder and moringa leaves powder through dietary supplementation in Guppy fish (Poecilia reticulata) on color development, growth and breeding performance parameters. Spirulina and moringa are rich source of protein and carotenoids. Four hundred twenty fishes were distributed into seven treatment groups T0, ST1, ST2, ST3, MT1, MT2, and MT3 with three replicates. Isonitrogenous feeds (40% protein) were made with fish meal, soya bean cake, rice bran, vitamin & mineral premix, dried moringa leave powder and dried spirulina powder. These ingredients were added in a predetermined concentration in moringa and spirulina test feed. Experimental control diet (D0) was prepared without spirulina and moringa supplementation. Spirulina treatment diets SD1, SD2, SD3 were prepared by adding 5%, 10% and 15% spirulina powder respectively. While moringa treatment diets MD1, MD2, MD3 were prepared by adding 5%, 10% and 15% moringa leave powder respectively. The fishes of group T0 were fed with diet D0, ST1 with SD1, ST2 with SD2, ST3 with SD3, MT1 with MD1, MT2 with MD2 and MT3 with MD3 @ 5% body weight per day. Spirulina and moringa does not adversely affect the water quality of aquariums. Spirulina and moringa treatments showed a significant improvement from control in length, weight, net weight gain and specific growth rate. Best growth was observed in ST3 treatments with 15% spirulina. The increase in spirulina and moringa concentration in fish diet showed an increase in survival but the survival was not significantly high in spirulina and moringa supplemented feeds from control. Significant increase in the concentration of carotenoids in fish tissue was observed with increase in spirulina and moringa concentration in fish feed and this increase can be observed in digital coloured photograph of the fish. Fertility per gram of fish increased with increase concentration of spirulina and moringa but only ST3 treatment with 15% spirulina showed significant improvement in fertility from control. A significant increase in fry length from control was observed in Spirulina and moringa diet treatments. Fry weight increased with increase in supplements (Spirulina and moringa) but the increase was significant only in ST3 treatment. With the increase in spirulina and moringa concentration in diet increase in fry survival was observed. The analysis of variance showed no significant difference in survival percentage for both spirulina and moringa treatments. The result of present experiment shows that spirulina powder and moringa leaves powder can be used as protein and carotenoid supplements in fish feed to improves growth, color development and breeding performance of Guppy fish.
