The quality characteristics of 15 kinds of the commercial northern sand lance, Ammodytes Personatus sauce (CNS) of korean traditional salt-fermented fish sauces were evaluated comparing to the traditional northern sand lance, Ammodytes Personatus sauce (TNS). The ranges of chemical compositions of the CNSs were $66.5\~71.0\%$ moisture, $19.3\~24.6\%$ ash, $4.7\~12.0\%$ crude protein, and the pH and salinity were $5.56\~6.47\%,\;24.0\~32.9\%$, respectively. Total nitrogen, amino nitrogen, total free amino acid and total ATP related compounds (sum of ATP$\~$IMP, HxR, Hx and uric acid) were in the ranges of 0.781$\~$ 1,918 g, 445.9$\~$1037.9 mg, 3,258.9$\~$6:562.6mg in 100 ml CNSs, and 4.766$\~$8.989 $\mu$mol in 1 ml CNSs. The CNSs were higher in content of moisture, TMAO, TMA and pH, but lower in content of crude protein, salinity, total nitrogen, amino nitrogen, total ATP related compounds, absorbance at 453 nm and total free amino acid than the TNSs, Both CNS and TNS samples were rich in free amino acids, such as glutamic acid, lysine, alanine, leucine, valine, aspartic acid and isoleucine in the order.
