The purpose of this study is to prepare the fish sauce front mackerel scrap which usually comprises $40{\sim}50%$ of raw fish in processing. Mackerel scrap was chopped, mired with equal weight of water, and then hydrolyzed by autolysis. The optimal conditions for hydrolysis of .mackerel scrap were at $55^{\circ}C$ for 4 hours. The maximum hydrolyzed rate of protein was 65% by autolysis. Crude protein content (6.5%) and color of mackerel sauce were similar to those of traditional soybean sauce. The abundant amino acids in mackerel sauce were leucine (22.8%), isoleucine (15.0%), phenylalanine (12.6%) and valine (12.5%). In sensory evaluation, mackerel sauce was at least equal to the traditional soybean sauce in product quality.
