Abstract: The 30 day recovery growth experiment was conducted in sea urchin (Strongylocentrotus intermedius) starved for different periods. Groups S0, S3, S6, S9, and S12 were deprived of food for 0, 3, 6, 9 and 12 days, respectively, and then refed at libitum ration levels. In the process, gonad weight, gonado -somatic index and gonad specific growth rate were observed. The results showed that there were significantly lower gonad weight and gonado - somatic index in Groups S6, S9, and S12 than those in Groups SO ,and S3. The sea urchin had maximal gonad specific growth rate at 2 or 4 days after they were refed. The histological observation showed that the structure of gonad was follicle type, consisting of germ cells and nutritive cells during growing stage in Group SO. The sea urchin starved had slow germ cell development and no more changes in nutritive cells and continued to develop after refeeding.
