| 摘 要： | 2005-2008年,在舟山海域银鲳(Pampus argenteus)繁殖季节(4-5月),随流刺网或张网捕鱼船出海,捕捞性腺成熟的银鲳,进行人工授精和孵化.人工授精试验采用干法、湿法和半干法,比较受精率和孵化率.通过4年连续测量银鲳成熟卵的卵径、油球径等形态指标,对卵子成熟度进行判别,在水温16.0～18.5 ℃、盐度28.0±0.5的条件下进行孵化.结果表明,以干法受精后间隔3～5 min水洗和半干法受精的方法受精率最高,受精率达18.50%～33.50%,最高达40%;孵化率达到43.83%～51.00%,最高达66%.银鲳成熟卵子的卵径为(1.368±0.082)mm,油球径为(0.550±0.031)mm,油球1个.对影响海捕银鲳亲体受精率和孵化率的环境条件也进行了讨论.

| Abstract: | Ripe silver pomfret,Pampus argenteus(male and female) were caught by gill net in the waters of Zhoushan,Zhejiang,at the spawning season(April to May) in 2005 and 2008.Eggs and milt were gently squeezed from female and male silver pomfret immediately after capturing.Artificial fertilization experiments were conducted by means of dry,semi-dry and wet method,respectively,and the consequent fertilization and hatching rate were compared.The egg maturity quality was discriminated by the morphological parameters,s... |
