In present work, the development of processing for various fermented sea foods using low-usefulness marine resources were investigated. The optimum temperatures of autolysis were 35$^{\circ}C$ for hair tail, 45$^{\circ}C$ for gizzard shad, 30$^{\circ}C$ for kangdale, 30$^{\circ}C$ for pen shell and 30$^{\circ}C$ for oyster and when alcalse(Novo Co.) were added, optimum temperatures were 60$^{\circ}C$, 50$^{\circ}C$, 50$^{\circ}C$, 50$^{\circ}C$ and 50$^{\circ}C$, respectively, and protease N, P. (Pacific chem. enzyme mixture 2,000) were 55$^{\circ}C$, 60$^{\circ}C$, 50$^{\circ}C$, 50$^{\circ}C$ and 50$^{\circ}C$, respectively. Especially although exozymes and endozymes reacted at same time, hydrolysis rate of raw materials got to maximum at optimum temperatures of exozymes. The facts showed that exozymes dominated the hydrolysis reached max8imum at pH 9.0, and optimum hydrolysis time of all raw materials were 6 hours. And the optimum concentrations of exozymes were about 3.0% for hair tail, 4.5% for gizzard shad, 3.5% for kangdale, 3.0% for pen shell and 3.0% for oyster, respectively.
