Abstract
Common carp is difficult for hatching naturally in the aquaculture ponds due to the
deterioration occurred with the natural hatching under environmental conditions, whereas the fry
production is less than artificial incubation.So, this study aims to utilize the artificial hatching process
to obtain high fertilization and fry production by using two types of incubators the Zug Jar (ZJ) and
the ordinary Poultry Drinker (PD). The practical experiments were carried under three water flow rates
of 1000, 2100 and 3200 ml/min for 9 liter volume of water and three egg densities per liter of 1000,
2000 and 3000 to determine the hatching ratio and fry production with taking into consideration the
water quality indicators including pH, dissolved oxygen and temperature during three days of incubation.
The obtained results revealed that the highest value for each of hatching ratio and fry production of
79±1.21% as well as 33±1.1fry/lit for ZJ as well as 76±1.23% and 27±1.12 fry/lit for PD, respectively
were achieved at the highest water flow rate of 3200 ml/lit and egg density of 3000 egg/lit, but the PD
still has the advantage of the low cost comparing to the ZJ, Generally, the both types of incubators
consumed large amount of water during incubation period resulting in low fry production and there an
urgent need to use a controlled incubator to reduce the wasted water and increase the fry production.
