摘要

血液涂片的常规观察反复表明,三倍体鱼比二倍体有更大比例的红细胞具有核分割(ENS);然而,目前还不清楚为什么会出现这种情况,以及它是否会影响红细胞功能。为了解决这一问题,我们检查了之前两次实验的血膜,以确定二倍体和三倍体brook charr Salvelinus fontinalis (Mitchill 1814)的饲养条件(驯化温度或溶解氧水平)和随后的急性有氧窘迫是否会影响ENS频率。正如预期的那样,三倍体的ENS频率高于相应的二倍体,但实验条件对三倍体ENS频率没有显著的生物学影响。ENS太罕见了,无法检测这些条件对二倍体的影响。

Acclimation conditions and subsequent acute hypoxia challenges do not affect the frequency of erythrocyte nuclear segmentation in triploid brook charr Salvelinus fontinalis (Mitchill 1814).

Routine observations of blood smears have repeatedly shown that triploid fish have a greater proportion of erythrocytes with nuclear segmentation (ENS) than diploids; however, there is as yet no understanding of why this is the case and whether it affects erythrocyte function. In an attempt to address this, we examined blood smears from two previous experiments to determine whether ENS frequency is affected by rearing conditions (acclimation temperature or dissolved oxygen level) and subsequent acute aerobic distress in diploid and triploid brook charr Salvelinus fontinalis (Mitchill 1814). As expected, triploids had a higher ENS frequency than corresponding diploids, but with no biologically significant effect of experimental conditions on ENS frequency in triploids. ENS was too rare to examine the effects of these conditions in diploids.

期刊介绍: The Journal of Fish Biology is a leading international journal for scientists engaged in all aspects of fishes and fisheries research, both fresh water and marine. The journal publishes high-quality papers relevant to the central theme of fish biology and aims to bring together under one cover an overall picture of the research in progress and to provide international communication among researchers in many disciplines with a common interest in the biology of fish.
