In this study was aimed to determine the
growth performance of rainbow trout (Onchorhynchus
mykiss, Walbaum 1792) fry
fed with feed containing essential
oils rosemary, cloves and rosemary + clove at different rates. In research, rainbow trout fries were used which initial weight 30 ± 5 g. Experimental
groups are that rosemary, clove and rosemary + clove essential
oils added the diets. These groups were as follow: Control group (no added any additive), % 0.5
Rosemary oil added R-0.5, % 1 Rosemary oil added R-1, % 1.5 Rosemary oil added R-1.5,
% 0.5 Clove oil added C-0.5, % 1 Clove oil added C-1, % 1,5 Clove oil added C-1.5, % 0,5 Rosemary + Cove oil added RC-0.5, %
1 Rosemary + Cove oil added RC-1, %
1,5 Rosemary + Cove oil added RC-1.5 group. Experiment lasted 60 day. Taken measured values were recorded in fish during trial.
At the end of the study it was calculated growth parametres; average live weight,
daily absolute live weight gain, relative growth rates, specific growth rate,
condition factor with viserosomatic and hepatosomatic factor. The
findings obtained in the study were
subjected to analysis of variance and the importance
degree of difference between the
groups was determined by Duncan's
multiple comparison test. In the light
of statistical data, daily
absolute live weight gains with the viserosomatic and
hepatosomatic index values
were found to be significant differences between all groups (p <0.05).
