| Abstract | ||||
| This study aimed to evaluate water parameters, the nutritive value, growth performance. fish productivity and economical efficiency of common carp (Cyprinus carp < /em>io) reared in rice fields that received weekly applications of nitrogen and phosphorus. at similar quantities, from three diHerent sources. Nine rice fields '(0.25 feddan each) were cultivated by rice and divided inlo three groups. The first group (T1) weekly received 150 kg total solid per feddan (Tslfed.) of poullry manure. the second group (T2) weekly received 300 kg Ts/fed. of dairy cow manure, and in the third group (13) 12.86 kg/fed. urea plus 26.3 kg/fed. triple super phosphate were applied weekly. All fields were stocked with common carp at a rate of 1500 fingerlings/led. 'Nith an average weight of 2.21 g. The growing season for common carp fish was 90 days. The obtained results showed that treatment applied had significant effect on final body weight. specific growth rate, body length and condition Iactor of common carp. The highest survival rate was obtained with group of fish on T1 (allowed by T2 and T3 treatments, respectively. The highest net production was recorded at T1 followed by T2 and 13 treatments. respectively. The contents of dry matter decreased according to the diHerent treatments while it was the reverse for the protein, fat and ash. Water quality was generally good in ponds fertilized with poultry manure than in ponds of other treatments. The highesl net return was recorded with group of fish on Tl followed by T2 and T3 treatments. respectively. In general, the results of this study indicate that the organic nutrient sources were more productive than the inorganic ones but the difference in effectiveness of poultry and cow manures was surprising. | ||||
