摘  要:
研究分析了唇(♀)*花(♂)杂交育种的特点和可行性.结果表明:2008-2011年,共计获得约164万粒受精卵,杂交F1鱼苗111.7万尾.在水温18~26℃条件下,唇(♀)*花(♂)的催产率、受精率和孵化率可达到85.5%~89.2%、80.6%~81.2%和80%~85.6%.在水温(20±1)℃条件下,杂交F1受精卵在受精后94h10min,仔鱼开始出膜.初孵仔鱼全长5.75~6.83mm.杂交F1成鱼的体色和体型与母本比较相近.唇(♀)*花(♂)的杂交育种是可行的.

摘  要:
The hybridization breeding between Hemibarbus labeo ( ♀ ) *Hemibarbus maculates ( ♂ ) by artificial method was studied in order to explore the hybridization possibility of Hemibarbus labeo ( ♀ ) * Hemibarbus maculates (♂). The results showed that 1.64 million fertilized eggs and 1.117 million F 1 hybrids were obtained by the crossing of Hemibarbus labeo (♀) * Hemibarbus maculates(♂)with artificial manipulation. from 2008 to 2011 years. Under the condition of 18~26 ℃ water temperature,spawning rate, the fertilizing rate and hatching rate, respectively 85.5%~89.2%,80.6%~81.2% and 80%~85.6%. Fry began to be hatched out at 94 h 10 min after fertilization under the condition of (20±1)℃ water temperature. The larva of hatching out just was 5.75 ~6.83 mm in the total length. Color and shape of the hybrid F 1 resembled H. labeo. It showed preliminarily that it was feasible for the hybridization breeding between Hemibarbus labeo ( ♀ ) *Hemibarbus maculates (♂).
