摘要
采用常规石蜡切片技术对人工养殖银鲳的性腺发育情况进行了研究。结果表明,在1～2月龄,养殖银鲳精巢处于第Ⅰ期;3～4月龄发育至第Ⅱ期;5月龄时发育至第Ⅲ期;6月龄时发育到第Ⅳ期;在7月龄时即能达到性成熟;在越冬的8～10月龄退化至第Ⅲ期,之后又开始重新发育,并在11～12月龄达到成熟。卵巢在3～4月龄时发育至第Ⅰ期;5月份发育至第Ⅱ期;6月龄发育到第Ⅲ期;7～8月龄的越冬时期卵巢退至第Ⅱ期;越冬之后的9～10月龄时卵巢继续发育,并在11～12月龄时达到性成熟。银鲳精巢和卵巢发育都为不完全同步型,且精巢发育较卵巢快。本研究为银鲳性腺发育及人工繁育研究提供了基础资料。
Gonadal development of the first year of life in cultured Pampus argenteus was studied histologically. At the age of first two months, testes were at stage Ⅰ , and then developed into stage Ⅱ in the following two months. At the age of 5, 6 and 7 months, testes developed into stage Ⅲ, Ⅳ and V, respectively. During winter （ age of 8 to 10 months）, testes degenerated into stage m, and then developed again and matured at the age of 11 to 12 months. Ovaries developed more slowly than testes. It developed into stage I at the age of 3 to 4 months, and at the age of 5 and 6 months, ovaries were found at the stage of Ⅱ and Ⅲ, respectively, During winter time, ovaries in fish at the age of 7 to 8 months degenerated into stage Ⅱ. After winter, ovaries developed again and matured at the llth - 12th month. The development of ovaries and testes was asynchronous. The results provided basic information for the gonadal development study and artificial breeding in Pampus argenteus.
