Outline of Final Research Achievements

Parasite infection in fish causes the decrease in quantity of fisheries resources and the lower the quality of fishery food. The infected fish muscle by parasites shows the softening by the increasing protease activity or the hardening. In this study, we investigated occurrence mechanism of these events. The results showed that biophylaxis of host against parasites affected the food quality of fish muscle.
