Abstract
It is common nowadays to use natural food additive to increase fish growth , activity and immunity .We study the effects of different levels (0 , 1 and 3%) of black seed (Nigella sativa ) on growth and blood glucose of common carp (Cyprinus carpio). The protein content of the experimental diets were 31.16 , 48.80 and 49.33 % for the three diets respectively while total energy was 441.61 , 464.61 and 475.72 kcal/100g respectively . Nine plastic tanks (30-L) were used in three replicates for each treatment to stock ten fish having the same initial weight (34.63 ± 6.51 gm/fish) in each. Fish were fed for satiation once daily, six days a week for 56 days.The results showed that the diet containing 1% black seed improved un-significantly (P>0.05) growth rate compared with control and diet containing 3% N. sativa. Blood glucose of common carp was significantly differ (P<0.05) in control and diet B in comparison to diet C, which accomplish the highest value 120.88 mm/dl.
