青鱼[Mylopharyngodon piceus (Richardson)]为我国特有的“四大家鱼”之一,是养殖对象中的优良品种。但青鱼人工繁殖时,即使采用人工授精,其受精率也很低,这对大量饲养青鱼鱼种有很大影响。鱼类存人工繁殖中受精率的高低,受很多因子的影响,诸如水体的生态因子,卵子的质量等,雄鱼精液也是重要因素之一。因此,找出影响受精率的原因,是提高青鱼受 The herring [Mylopharyngodon piceus (Richardson)] is one of the “four major domestic fish” peculiar to China and is an excellent breed of breeding objects. However, artificial breeding of herring, even with artificial insemination, fertilization rate is also very low, which has a large impact on the breeding of a large number of herring species. The level of fertilization in artificial fish stocks is affected by many factors, such as the ecological factors of water body, the quality of eggs and so on. Male sperm is also one of the important factors. Therefore, to identify the reasons for fertilization rate is to improve the herring by
