Abstract


The purpose of this this study was to complete the data from the specialized literature regarding some morphological charactersof male and female breeders of brown trout (Salmo trutta fario), exploited in Fiad trout farm, Bistrița-Năsăud County, Romania. The body mass (Bm) of males ranged from 0.67 kg to 1.39 kg with a mean value of 0.96 ±0.07 kg. The body mass of females (Bm) ranged from 0.50 kg to 0.90 kg with a mean value of 0.73±0.04 kg. In terms of descriptive statistics, the values of variability of studied characters, both males and females, are low. This low variability, shows the existence of a good homogeneity of the breeding group from Fiad trout farm.The One-Way ANOVA analysis showed that there is no statistically significance difference for the means of studied characters, except for commercial length and small perimeter of fishes. The results of t-test for showed that there is a statistically significance difference between the measurements and the gender of the specimens.
