In this study, were considered productive performance of juvenile Frăsinet carp, raised in intensive systems in a systematic ciprinicol farm. The inspection fishing activity carried out by an interval of about two weeks, at random, was body weight at different ages, and based on them, increase medium rais up. Also, main measurements were made tangible and corporal indexes have been calculated. Somatometric raw data were statistically processed and the following parameters were calculated: mean, standard error of the mean, variance, standard deviation and coefficient of variability. The summer I growth of populating, average weight of juveniles varied between 0.2-1.0 g/fish, and at the end of growth, fall, summer I juvenile has reached an average weight of 40-90 g/fish. Juveniles showed a good growth rate, according to the pond, the total average increase from populating the tanks until harvest fishing being 39.8-89.7 g/fish in 2009 (body weight increased by 199-299 times), 69.8-89.8 g/fish in 2010 (+349-449 times) and 74.0-89.0 g/fish in 2011 (+74 times). The main phenotypic features of summer carp Frăsinet, differs from the carp native populations, especially in relation to body length (total length and the standard 12.0 cm, respectively 11.5 cm,), the maximum height of the body (5.5 cm), high perimeter 11.5 cm, thickness trunk 5.4 cm, caudal of the peduncle length 3.7 cm. Except large trunk length and perimeter, the other body dimensions population analyzed is quite heterogeneous, as evidenced by the heritability coefficient values (13-28%). In first summer, the Frăsinet carp, demonstrated a correct conformation and a good body the proportionality of the optimal values of corporal indexes: 2% index of fattening, 2.1 profile index, 0.99 quality index, 47% index of thickness and 32.3% carnosity index.
