Abstract: <\/strong><\/span><\/p>\n

  The experiment was designed to study the effect of using fertilizing on the growth of grass carp Ctenopharyngodon idella<\/em> juvenile reared floating cages developed in an earthen ponds of marine science center, The study continued for six weeks of period from 1\/4\/2020 to 15\/5\/2020. The cages was (30 x 30 x 60) cm3 <\/sup>in size , the cages immersed to a depth of 40 cm. six cages were used, with a duplicate of each cage. In cage A the fishes was feed on a standard diet, cage B adding a birds droppings as an organic fertilizer, in cage C urea used as a chemical fertilizer, 20 juveniles of the experimental fish were placed in each cage. the fishes depend on a natural dissolves oxygen in the ponds, the result  shows that the rate of the length and weight in the cage A 4.8 cm and 121.16 g, cage B 5.3 cm and 173.26 g, cage C 5.1 cm and 132.78 g, with weight increased 54.76 , 97.95 , 57.17% and with a relative growth rate of 160.68 , 230.06, 175.62% , with a survival rate 70%, 98% , 85% for the cages A, B and C respectively. The results showed that organic fertilizing increased the growth rates of the experiment fishes clearly in the cage C  compared to other cages without any side effects and it was the best way to using a fertilize.<\/span><\/p>\n
