| 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. |
