　　本研究通过对短蛸(Octopus ocellatus)受精卵室内控温孵化实验,并采用直线回归、Sine模型模拟等数理统计学方法,研究其发育的生物学零度(C)、有效积温(K)、胚胎发育的温度系数(Q10)和胚胎发育时期(Ts)与生长积温(K)的相关性。结果表明,短蛸受精卵发育的生物学零度为5.15℃,受精卵发育到初孵幼体的有效积温为589.45℃·d,胚胎发育最适温度范围为19.46-23.06℃。利用Sine模型计算出的各温度下胚胎发育积温模拟值,与实际有效积温无显著差异。在不同温度条件下,短蛸胚胎发育至各个时期的生长积温需求总量是一致的,胚胎发育阶段所处时期(Ts)和生长积温(K)呈线性函数关系：K=26.72Ts+55.34(R2=0.996)。本研究获得了关于短蛸胚胎发育生物学零度和生长积温的相关信息,为短蛸人工育苗、渔业资源管理等提供有力的理论支持；Sine模型作为一种有效的积温模拟估算方法可为其它海洋生物胚胎发育研究提供借鉴。

With the help of mathematical statistics method and conducting indoor incubation experiment under con-trolled temperature, we studied the biological zero (C), effective accumulated temperature (K) and temperature coefficient (Q10) for the embryonic development of Octopus ocellatus as well as the correlation between the embryonic stages (Ts) and K. We found that the C for the embryonic development of O. ocellatus is 5.15℃, the K at which the zygotes develop into early juveniles is 589.45℃·d, and the optimum hatching temperature ranges from 19.46℃ to 23.06℃. We compared the linear regression method with Single Sine method, which was using to simulate the accumulation of K, the results have no significant differences with the K has been inferred. The K is a fixed value for zygotes develop into any representative em-bryonic stages under different temperature conditions. There is a significant linear correlation between Ts and K: K =26.72Ts+55.34 (R2=0.996). These results will provide a theoretical support for artificial breeding and fishery resources management. Single Sine method was a useful practical tool for calculating effective accumulated temperature deserved for reference in the further embryonic development research.
