| 摘要: |
| 在不同的温度下对新疆艾比湖卤虫休眠卵进行了孵化试验,研究了卤虫发育速度与温度之间的关系,提出了相应的数学模型;V(T)=(k·T+c)·(1-exp(-(T-TH)/rH));并以此求算了该种群休眠卵孵化的最低临界温度为5.56℃,平均临界温度为5.96℃,最低有效积温为342.47℃×h,平均有效积温为413.63℃×h;同时还就最适温度、耐温上限比较了高能卵与均能卵在适温能力上的差异,并最后讨论了这些参数在集约化养殖中的实践意义. |

| Abstract: |
| The hatching time of Artemia parthenogenetica of Aibi Lake at different temperatures is tested.According to the relationship between developmental rate and temperature, the mathematical model is established as following:V(T)=(k·T+c)·(1-exp(-(T-TH)/rH)), where V is developmental rate, T is temperature and other parameters are calculated based on the test data.From these, we compute the minimum and the average threshold of development (Tmin-0, Taver-0), the minimum and the average cumulative temperature (Qmin, Qaver)are:Tmin-0=5.56℃, Taver-0=5.96℃, Qmin=342.47℃·h, Qaver=413.63℃·h.Additionally, the different abilities at suiting temperature of cysts are discussed accomplishing with the fittesttemperature and high lethal-temperature.Finally, the signif icance of these factors in breeding aquatics was expatiated on. |
