Abstract
The study was conducted in special cages in a mud pond, Agricultural Research
and Experiment Station, Animal Production Department, Agriculture College,
Al-Muthanna University, from 1/10/2020 to 10/12/2021to study the effect of different levels of nutmeg on some growth parameters of common carp. A total of 100
common carp fish, Cyprinus carpio, were brought from a private fish breeding lake
in Al-Qadisiyah Governorate, Al-Mihnawiya District, with an average weight of
±.94 gm. 80 fish were selected and distributed randomly and evenly to the experimental cages, put in each aquarium 5 fish for acclimatization, the fish persisted
during the acclimatization period, which amounted to 10 days, were starved for
one day and then fed with 1% of the weight of the live mass in each tank at the rate
of two meals per day. The four treatments were T1 control, T2 0.005%, T3 0.01%
and T4 0.015% nutmeg. The results indicated a significant decrease in the final
body weight, weight gain, daily growth rate, relative growth rate and specific
growth rate in all nutmeg treatments compared to the control treatment.
