饥饿对月鳢几项血液指标的影响

对体长145．77±12．21cm，体重35．42±8．51g的月鳢（Channa asiatica）在正常摄食和饥饿4～20d状态下的几项血液指标进行了恻定。结果表明：饥饿组与对照组相比，随着饥饿时间的延长，月鳢的红细胞数量极显著减少（P〈0．01）；血红蛋白含量在前8d内是升高的，随后下降；血液中红细胞的渗透脆性有所上升，16d和20d差异显著（P〈0．05）；白细胞数量在整个饥饿期间一直呈上升趋势，在饥饿的第8d的测试中，白细胞数量的增加差异显著（P〈0．05），12d以后的测试中白细胞数量的增加差异极显著（P〈0．01）。

The effects of starvation on the blood indices in Channa asiatica

Different starvation periods were set to examine the variation of hematologic indices in Channa asiatica. The blood was sampled at days 0,4,8,12,16 and 20 of starvation period. The results showed that the number of erythrocyte sharply decreased（P 〈0. 01 ） in the blood of starving group during starvation. The hemoglobin content increased in first 8 days, then kept decrease while the erythrocyte osmotic brittleness sharply increased（ P 〈 0. 05 ） at days 16 and 20 starvation. But the number of leukocytes increased （ P 〈 0. 05 ） during the experiment period, especially （ P 〈 0. 01 ） after 12 days.
