湖鳟胚胎暴露于溶解O2水平接近2.5，3.5，4.5，和10.5 ppm在4个温度，2.5[degree]C，5.0[degree]C，7.5[degree]C，和10.0[degree]C，从受精到后期发展阶段。3种低O2水平引起发育速率的延迟，导致延迟孵化和延长孵化期，减少卵黄循环结构，以及头部和躯干的异常。在10[degree]C下的低O2水平在孵化之前引起总死亡率。对这些结果进行了讨论并与以前的发现进行了比较。|| 摘要认证：Auth. Abst
Lake trout embryos were exposed to dissolved O2 levels approximating 2.5, 3.5, 4.5, and 10.5 ppm at each of 4 temperatures, 2.5[degree]C, 5.0[degree]C, 7.5[degree]C, and 10.0[degree]C, from fertilization to a late stage of development. The 3 low 02 levels caused retardations in the developmental rates resulting in delayed hatching and lengthening of the hatching period, reduction of vitelline circulatory structures, and abnormalities of head and trunk. The low 02 levels at 10[degree]C caused total mortality just prior to hatching. These results are discussed and compared with previous findings. || ABSTRACT AUTHORS: Auth. abst
