从长江支流泸州龙溪河收集野生厚颌鲂 ,直接或经驯养后进行人工繁殖 ,并对胚胎发育过程进行了描述 ,旨在为厚颌鲂资源的增殖与开发提供参考。 3次未催产的人工授精实验 1次成功 ,受精率 12 0 % ;16次催产试验共注射了 32尾雌鱼 ,平均催产率 6 2 5 % ;12次有效催产的平均受精率 6 2 1% ,孵化率 4 4 7%。每千克鱼注射 3mgPG +3ugLRH A2 ,可以获得较好的催产效果。胚胎发育过程可分为 18个时期 ,温度对发育进程具有显著的影响。
Wild thick-nosed gudgeons were collected from the Longxi River, Luzhou, a tributary of the Yangtze River, and directly or after being domesticated for artificial propagation. The development of the embryo was described in order to provide reference for the proliferation and development of the giant jaw galls. Three times of unfertilized artificial insemination experiments were successful in one time, with a fertilization rate of 12%. Thirty-two females were injected in 16 oxytocin experiments with an average rate of 65.5%. The average fertilization rate of 12 effective oxytocin groups was 62.1% , Hatching rate 4 4 7%. Each kg of fish injected 3mgPG +3 ugLRH A2, you can get a better oxytocin effect. Embryonic development can be divided into 18 periods, temperature has a significant impact on the developmental process.
