亚成体癍点叉尾（Ictalurus punctatus）暴露于亚致死低氧24、48和72 h。血液学参数被用来评估鲶鱼的生理状态进行长期的，亚致死性缺氧。缺氧24、48和72 h后，癍点叉尾鮰的血红蛋白、平均红细胞血红蛋白、平均红细胞血红蛋白浓度、血浆乳酸和血浆葡萄糖与对照组有显著差异。红细胞压积、血浆总蛋白、红细胞总数、白细胞总数、平均红细胞体积和白细胞分类计数对鲶鱼的生理状态并不敏感。五天后，重新适应的氧饱和度，通道鲶鱼继续表现出长期缺氧的血液学反应。
Sub-adult channel catfish, Ictalurus punctatus, were exposed to sublethal hypoxia for 24, 48 or 72 h. Haematological parameters were used to assess the physiological state of the catfish subjected to prolonged, sublethal hypoxia. Haemoglobin, mean corpuscular haemoglobin, mean corpuscular haemoglobin concentreation, plasma lactic acid and plasma glucose deviated significantly from control values in channel catfish exposed to hypoxia for 24, 48 or 72 h. Haematocrit, total plasma protein, total erythrocyte counts, total leukocyte counts mean corpuscular volume and differential leukocyte counts were not sensitive indicators to the catfish's physiological status. After five days, of reacclimation to oxygen levels saturation, channel catfish continued to exhibit haematological responses to prolonged hypoxia.
