摘要:
本文研讨了各种人控恒温和自然水温对红整整虾胚胎发育周期,各发育阶段以及胚胎发育成活率等的影响在水温24-30℃,红螫螫虾的胚胎均能正常发育;最适发育水温为28-30℃.22℃以下或32℃以上,胚胎不能正常发育,自然水温温差大,对胚胎发育有害水温越高,胚胎发育越快,发育周期越短,成活率越低.

Abstract:
The effects on embryonic development of the cherax quadricarinatus at water temperature which included seven sets of 22℃, 24℃, 26℃, 28℃, 30℃,32℃ and ambient temperature were studied by light microscope from 1997 to December, 1998.The results showed briefly in the following: The water temperature ranges from 24℃ to 30℃ were suitable for embryonic development of the shrimp, beyond this water temperature ranges, it would be dangerous or lethal to the shrimp;This optimum water temperature for embryonic development of the shrimp was 28℃ to 30℃;The development of the embryo was quite sensitive to water temperature, the higher water temperature was, the less time embryonic development spent, but embryonic survival rate was gradually decreased.
Key words:  Cherax quadricarinatus  embryonic development  water temperature
