The influence of sharp temperature shift and proportioned keeping of the sevryuga females at a low temperature on the oocyte maturation and ovulation has been studied. The reaction of the follicles to similar influences was shown to differ at different stages of the period of maturation inertia: the follicles remained intact at the stages prior to the germinal vesicle (oocyte nucleus) breakdown, were damaged in a part of females at the prometa- and metaphase I and in the most females at the prometa- and metaphase II. The injection of triiodothyronine to the females subjected to cooling at different stages of the period of maturation inertia exerted no effect on the oocyte ovulation and the egg fertilizability.
研究了急剧的温度变化以及将梭鲈雌鱼在低温下按比例饲养对卵母细胞成熟和排卵的影响。结果表明，在成熟惰性期的不同阶段，卵泡对类似影响的反应有所不同：在生发泡（卵母细胞核）破裂之前的阶段，卵泡保持完整；在第一次减数分裂前期和中期，部分雌鱼的卵泡受到损伤；在第二次减数分裂前期和中期，大多数雌鱼的卵泡受到损伤。在成熟惰性期的不同阶段对接受降温处理的雌鱼注射三碘甲状腺原氨酸，对卵母细胞排卵和卵子受精能力没有影响。
