Abstract: The changes in protein metabolism were studied in shrimp Marsupenaeus japonicus weight of （ 13.08 ± 2.40 ） g and total length of （ 10.37 ± 0. 73 ） cm during starvation and with initial wet refeeding. The shrimp in Group C was fed to satiety for 10 days, and the shrimp in Groups S10, S15 and S25 were deprived of food for 10, 15 and 25 days, respectively, and then fed to satiety for 10 days. The results showed that the starved shrimp had a rapid increase in protein content in muscles during the first 15 days, and then maintained this protein level in the following 10 days, but the protein content in the hepatopancreas was always constant. During the course of refeeding, the protein content decreased in the muscles, but increased in the hepatopan- creas. During the starvation period, the plasma protein levels kept stable at the first five days, and decreased during the subsequent 10 days （5 - 15 d） , and then recovered again. After refeeding, there were increase in plasma protein levels in all the groups except the group S25. There was significanty higher plasma protein lev- els in the treatment groups than in group C. Food deprivation caused a slightly decline in RNA/DNA ratio in the muscles at the first five days, and then kept constant, while there was an increase in RNA/DNA ratio in the hepatopanereas after short - time decline. After refeeding, the ratio of RNA/DNA in muscles increased gradually in all groups except Group S25, while the ratio of RNA/DNA in hepatopancreas was a significant increase in all groups except Group C.
