Abstract: (9245 Views) |
| Effect of different levels of dietary supplementation of Spirulina on growth indices and carcass
composition of Benny Mesopotamichthys sharpeyi was investigated in an 8 week experimental trial. Dried
and powdered spirulina algae in five levels of 0, 2.5, 5.0, 7.5 and 10.0 % were added to the experimental
diet. Experimental fish were fed to satiation twice daily. The results showed significant difference
(P<0.05) in final weight and weight gain of the experimental fish fed 10% supplementary diet compared to
control treatment. However, specific growth rate and condition factor did not show significant difference
among treatments (P>0.05). Feed conversion ratio and protein efficiency ratio in 10% treatment showed
significant difference (P<0.05) with control group. Though significant difference (P<0.05) was observed in
whole body protein content between 10% (14.07±0.12%) and control treatments, the results showed that
various levels of spirulina algae in diet did not affect the fat, ash, moisture, carbohydrate and energy
content of the experimental fish. The results indicated that 10% dietary supplementation of spirulina could
improve final weight, weight gain, specific growth rate, condition factor and body protein content of
Benny fish. |
