摘要
对黑莓鲈(Pomoxis nigromaculatus)的胚胎发育进行了连续跟踪观察,并探讨了水温对其胚胎发育的影响。结果表明:水温(24±1)℃时,孵化时间为40.23 h;胚胎发育的温度系数Q10值为2.01,适宜胚胎发育的温度范围为22℃~24℃;孵化温度与孵化时间呈负相关关系;温度与孵化率的回归方程式为:y=25.899x-0.5 407x2-216.92(R2=0.9 217);温度与畸形率之间的回归方程式为:y=0.5 496x2-22.857x+236.44(R2=0.9 422);胚胎发育生物学零度为10.22℃,有效积温为(545.14±22.60)^(554.42±22.74)℃·h。
The embryonic development of Pomoxis nigromaculatus were observed continuously,and the effects of water temperature on the embryonic development were discussed.The experimental results showed that hatching time was 40.23 h at the water temperature（24 ± 1）℃.The Values of Q10 of embryonic development of Pomoxis nigromaculatus was 2.05,and the suitable temperature range for fertilized eggs hatching was 22℃ - 24℃.There was a negative correlation between water temperature and hatching time.The regression equation between temperature and hatching rate： y = 25.899x- 0.5 407x2- 216.92（R2= 0.9 217）; the regression equation between temperature and abnormality rate： y = 0.5 496x2- 22.857 x ＋ 236.44（ R2= 0.9422）; and the biological zeros point of Pomoxis nigromaculatus was 10.22℃,the effective accumulated temperature was（545.14 ± 22.60 - 554.42 ± 22.74） ℃ ·h.
