Abstract :
Currently, white fish or Kutum Rutilus frisii is considered to be a good candidate for commercial
aquaculture. However, little information is available regarding the nutritional requirement of this fish fry.
Experiments were conducted to examine the effects Daphnia magna as live food cultured on two freshwater
green algae, Chlorella sp. and Scenedesmus obliquus enriched with different B group vitamin dosages (0.00 as
control, 0.50, 1.00 and 2.00 mL of enriching solution per liter of algae culture medium) on the growth and
survival rates of Rutilus frisii kutum fry. Results demonstrated that increasing in B group vitamin dosages are
caused an increasing in nutritional value (Kcal) of two freshwater green algae species Chlorella sp. and
Scenedesmus obliquus significantly. Significant differences were observed in BWG (%) and SGR between
different vitamins treatments both the fed Daphnia magna cultured on Chlorella sp. and Scenedesmus obliquus
enriched (P < 0.05) but not in survival percentage (P > 0.05).
