Abstract
In breeding environments, in order to know the fate of the fish given to the fish, the biomass and control of fish growth should also be monitored during the breeding period to determine the growth rate and feed conversion ratio (FCR). For this purpose, 20 rainbow trout (31.42±3.81) were randomly selected. They were then divided into groups A and B. Group A fish fed 1.5% body weight and group B fish fed 2.4% body weight. The length and weight of each fish were measured. Samples were taken in the photographic chamber to calculate the environment, area, height and diameter equivalent to fish in the bioassay. Based on the results of the present study, the interval between the two biometric of final weight, final average length and final height were 39.26 ± 4.91 g, 15.05±0.7 cm and 3.45±0.45 cm respectively and in group A 36.01 ±2.59 g, 14.77±0.62 cm and 3.06±0.26 cm, respectively, which had increased with increasing percentage of feeding. Also final area, final environment and final diameter increased with increasing percentage of nutrition relative to body weight (p
