| Abstract | ||
| Four feeding treatments of common carp Broad stock were conducted involved the following:(T1:Good feed (with 23%protein) with manuring , T2:Simple feed (rice) with manuring , T3: manuring only, T4: buying the brood stocks from local market). No Significant difference was noticed between T1 and T2 , and also betweenT3 and T4 for all the studied characteristics (response rate , egg weights / group, egg weight to body weight ratio, produced fingerlings number and permanency ratio). T1 and T2 were Significantly(p<0.05) greater thanT3 and T4 for the all studied characteristics, meanwhile the economic evaluation of the studied hatcheries, showed that the highest costs were in T1 while the lowest costs was in T3. The total income was the highest in T1 and the lowest in T3, the highest profit was achieved in T2 (38.400 million Iraqi dinar) which depends on simple feeding with rice and manuring , then T1(37.280 million Iraqi dinar) followed by T3(10.650 million Iraqi dinar) and the last T4 (6.290 million Ira dinar) . | ||
