Abstract

The effect of exposure on the hematological parameters of the red claw crayfish Cherax quadricarinatus Von Martens 1868 has been studied. The hemolymph is taken immediately after extraction from the water after 2, 4, and 8 h of exposure on the shore and 24 and 72 h after returning to the water. The total hemocyte counts (THCs), hemogram, general protein, and hemocyanin disease are determined. The dynamics of the growth of hematological parameters in the temporal aspect is revealed: THC and the proportion of granulocytes increase to reveal the entire pattern of growth, the proportion of agranulocytes, and the total content of protein and hemocyanin. After exposure on the shore, the color of the hemolymph changes from bluish with a grayish tint to cloudy gray-green (deviation from the norm). The data indicate the development of compensatory factors and pathological properties in response to stress and the occurrence of symptoms in the air, which can be used in practice in assessing the state of the red claw crayfish in the process of transport.

澳大利亚红爪小龙虾暴露于空气时的血液学参数

摘要

研究了暴露对红螯螯虾Cherax squarecarinatus Von Martens 1868血液学参数的影响。暴露在岸上 2、4 和 8 小时以及返回水中 24 和 72 小时后，从水中提取后立即采集血淋巴。测定总血细胞计数 (THC)、血象、一般蛋白质和血蓝蛋白疾病。揭示了血液学参数在时间方面的增长动态：THC 和粒细胞比例增加，揭示了整个生长模式、粒细胞比例以及蛋白质和血蓝蛋白的总含量。暴露在岸上后，血淋巴的颜色从带灰色调的蓝色变为浑浊的灰绿色（偏离正常值）。这些数据表明了响应压力和空气中症状发生的代偿因素和病理特性的发展，可用于实际评估红螯虾在运输过程中的状态。
