Description:
In order to investigation use of different ration from acorn meal in diet of rainbow trout as a plate
binder and nutrient, The experiment was carried out in complete random in design. The treatments were
1,2,3 and 4, which contained of 0,2,4,6 percent of acorn meal in different diets respectively. Four repeat
had been make in each treatment. This experiment were conducted on 1600 Juveniles rainbow trout
with initial average weight of 74 gr, for 120 days after antiseptic processes in 16 polyethylene pound of
1.8 1.4 0.9 m length, width and depth respectively, in Boldaje station in Chaharmahal and Bakhtiari
province. The diets were formulated with local material which could providing nutritive requirement of
rainbow trout in principle of NRC with UFFDA soft ware dietary, as diets contained of 0,2,4,6 percent
Acorn meal and other nutrient were equal. The feed were given 3 time a day on biomass basis of
pounds. During of experiment, once every two weeks, after anaesthetize 50 percent of fishes in each
pound were measuring a bout weight and length and the data were taken. At the final of experiment for
determination of carcass characteristics, comprising of crud protein, fat, ash and dry matter, 10 fish
carcass of each pounds were analyzed by AOAC procedure after removal of fins, fill gut and head, The
results showed which final weigh increase was more in treat 4 and have been significant differences
with others. The greatest length was observed in treat four which had significant differences with treat 1. Feed consumption were not significant differences between any treats, but was more in treat 4. Feed
conversion ratio affected by treat, and the best was in treat 4, which had significant, differing with treat
1. For carcass characteristic, all treat was similar, exception for ash which more in treat four. Diets
stability showed that the least stability was in treat 1 and the highest was seen in treat 4. The result of
this study showed that we could use of acorn meal such as nutrient and plate binder because effect on
fish rising, because improvement in fattening performance and carcass characteristics in diet of rainbow
trout.
