| Abstract | ||
| The effect of natural and three kind of artificial foods studied on growth rate and survival of Barbus sharpyie larvae with length rate 9 mm and weight rate 0.00098 gm . Floating cages were chosen as a control environment reared in earthen pond, , the cages were distributed to be 1,2,3 which feed on artificial food and 4,5,6 which depends on natural food from April to May 2010 . 30 larvae used in each cage 1 larvae /1.2 liter of water density ,The environmental parameters , the length rate , weight rate , survival and growth rate was studied . The environmental parameters shows that all of the parameters were suitable for the culture of Barbus sharpyie. The result shows that a significant shift in food was occurred according to age .the result shows that the highest rang of length was 46, ,43,39 mm with weight rate 2.0340 , 1.8771,1.0650 gm, and survival 90%,85%,75% in the cages 1,2,3 with top grains increase weekly rate 1.3501, 1.0084 ,0.8885 gm/week and lowest grains increase weekly rate 0.0025 ,0.0012,0.0005 gm/week constantly . and highest rang of length 31,30,27 mm, with weight rate0.9842 , 0.7683, 0.2261gm in cages 4,5,6 with top grains increase weekly rate0.7317,0.4389 ,0.1132 gm/week and lowest grains increase weekly rate 0.0009,0.0069 ,0.0004gm/week constantly with survival 70% ,65% and 60% 1n cage 4,5 and 6 constantly. This study is to learn The effect of natural and three kind of artificial foods on growth rate and survival of Barbus sharpyie larvae Cultured in Floating cages | ||
