| 摘 要： | 丁是我国新疆地区经济鱼类之一,也是近年来养殖、增殖的渔业对象之一。对新疆地区丁卵巢周年变化和卵母细胞发育的观察结果表明,丁性成熟年龄在3~4龄;繁殖期在5月下旬-7月下旬,期间卵巢成熟系数在11.50%~12.25%,平均为11.88%;繁殖期过后,部分未产出的成熟卵退化,吸收,从11月至来年3月其卵巢发育处在重复发育的II期,至翌年4月卵巢再次发育;根据卵巢发育特点,丁属分批产卵类型。

| Abstract: | Tench,Tinca tinca is one of the important economic fishes and a new species of fish of farming and stocking in inland waters in Beitun area,Xinjiang.The annual histological changes in ovary of tench were investigated.The result showed that the age of maturity of tench was 3-4-years old in Beitun area.The spawning season was from the last ten-day of May to July.In this period,the mature coefficient of ovaries was 11.50%-12.25%, with an average of 11.88%.The oogenesis was composed of five consequent phases.After spawning,few mature oocytes were re-absorbed subsequently in ovary and the ovary soon degenerated into stage II and remained in this stage from November to Match next year and began to develop again in the next April.According to the histology of oocytes and investigation of field works,tench should be classified into batch-spawing fish. |
