摘要
Abstract
This paper revealed the annual changes of the ovary stage for development and developmental phase of oocytes by means of microscope observation of ovarian olefin slice* as well as the relationship a-mong gonadosomatic index, hepatosomatic index and condition factor of female ovoviviparous Sebastes schlegeli. According to the morphological and histological features, the ovarian development could be divided into seven stages and the growth of oocytes could be divided into six phases. The ovary was in stage M in winter, gravid in May, and developed into stage II from middle July, then rested on the stage II until November. The average gonadosomatic index of female Sebastes schlegeli during a year was between 0. 33 and 19. 82, the hepatosomatic index was between 0. 33 and 3. 10, and the condition factor was between 2. 51 and 3. 20. The relationship between gonadosomatic index and hepatosomatic index was basically positive correlation before parturition, and then hepatosomatic index dropped significantly. The results of this paper indicate that this fish spawn only once a year.关键词
