摘要
:用含HCG及鲤脑垂体 (PG)匀浆液提取物 (CPE)的W /O/W复乳 ,对塘养雌鳗进行注射催熟实验。雌鳗平均GSI达 35.18% ,最高达 56.5% ,其催熟效果较常规注射方法 (平均GSI 2 7.9% ,最高 50 .4 % )好。用含LHRH A、HCG、CPE的复乳和DOM生理盐水混悬剂对部分达到性成熟的鳗鲡进行催产 ,用W /O/W复乳诱导成熟的鳗鲡 ,排卵率为 75% ;用常规方法催熟的鳗鲡排卵率为 55%。注射复乳制剂后 ,鳗鲡血清GtH含量可较长时间的保持较高水平 ,血清GtH的变化较常规注射方法缓和。注射乳剂还可使鳗鲡脑垂体GtH含量升高。
Female cultivated eel (Anguilla japonica), body weight 330～680 g, body length 62～67 cm, were employed without being fed during the experiment with water temperature 14～25℃, salinity 30～34 and natural light intensity. In the gonadial maturation induction test, by injecting the W/O/W (water oil water) multiple emulsion 12 times at 7 d intervals, containing HCG & CPE (carp pituitary extraction), the average GSI of the eel increased to 35.1% with the highest 56.5%. While the average GSI in the groups injected with routine HCG & CPE is 27.9% with the highest 50.4%, lower than that in the W/O/W groups. In the ovulation induction test the female eel were induced by injecting the W/O/W multiple emulsion (containing LHRH A, HCG and CPE) and DOM. The ovulating rate of the eel in W/O/W groups was more than those in routine HCG & CPE groups. The serum GtH levels in W/O/W groups remained significantly higher than those in routine groups.
