| Abstract | ||
| Air flow and circulating water system were used in hatching eggs of bunni (B. sharpeyi) and common carp (Cyprinus carpio). The eggs were placed in a funnel with the air and water underneath. Present study showed the efficiency of this method which is better than classic method (circulation water system). The hatching percentage and hatching period of B. sharpeyi by using air flow were 72 % and 60 hr., respectively, while in C. carpio they were 84% and 56 hr. respectively.Whereas the hatchery percentage and hatching period with the use of circulating water system for B. sharpeyi were 57% and 65 hr., respectively, and 80 % and 62 hr. for C. carpio. The air flow method is characterized by reduced amount water used; lower of energy and better protection of eggs from disease, especially fungi. | ||
