Abstract: 

This study was conducted in a private fishery at the Sheikh Saeed area – Aleppo province -Syria on carp fish, to improve some productive traits and estimating their genetic indicators, through flock selected previously for the best productive characteristics. In this experiment (50 fish) were used. Productivity measurements were taken for some meat production traits (live body weight, total length, body depth, head length) from the age of marketing (6-7 months) until the age of sexual maturity (1.5-1 years). The results indicated that the estimates of the heritability for some productive traits were (0.50, 0.43, 0.37, 0.27 ) for (total length, total weight, body depth, and head length respectively), while the estimates of the genetic correlation between the live  body weight trait with both total length and body depth were positive and relatively high, while the genetic correlation coefficients between the most of the productive traits were negative and  relatively low, while the estimates of the phenotypic correlation between total length and (live weight, body depth, head length) were positive and  relatively high.

Keywords: common carp, selection, genetic parameters, phenotypic correlation.
