摘要
为了解温度对光倒刺鲃胚胎发育的影响,观察了在3种温度条件下光倒刺鲃胚胎发育的过程.结果表明:在17℃条件下,胚胎不能完成发育过程;在23℃～25℃及24℃～27℃条件下,胚胎能正常发育,且孵化率均超过95%;在一定的温度范围内,较高的水温条件使胚胎发育阶段时程缩短.24℃～27℃条件下胚胎畸形率稍高,但与23℃～25℃条件相比差异不显著.
The paper observed Embryonic development of Spinibarbus hollandi in different temperatures,and found out that Embryonic development failed in 17 ℃ while succeeded in 23 ℃ to 25 ℃ and 24 ℃ to 27 ℃,and both hatchability was over 95%.The paper also found out that rate of Fetal malformation is a little high in 24 ℃ to 27 ℃,while the difference was not significant between 23 ℃ to 25 ℃ and 24 ℃ to 27 ℃.
