摘要

鱼类健康评估对于维持可持续的水生生态系统以及确保野生和养殖鱼类种群的健康至关重要。血液学参数是鱼类健康的重要指标,而红细胞增多症则是具有重要诊断价值的基本标志物。红细胞增多症是指血液中的红细胞形状异常,反映了潜在的生理和病理状况。Poikilocytosis 可发生在各种鱼类物种中,并可能受到环境压力、传染病病原体、营养缺乏和接触污染物的影响。红细胞形态的改变,如棘突细胞、棘细胞、达克细胞、裂殖细胞、球形细胞和鳕鱼细胞,是鱼类常见的 poikilocytosis。了解 poikilocytosis 与鱼类健康之间的关系对疾病诊断、监测、监控和管理具有重要意义。通过量化 poikilocytic 的变化,研究人员和兽医可以区分正常变化和病理情况,从而促进有针对性的干预和治疗策略。虽然大多数研究都集中在重金属毒性、应激因素、营养缺乏、污染物和治疗方面,但在鱼类健康中诱发嗜碱性细胞增多症的病因却被忽视了。尽管如此,嗜水细胞增多症仍然是评估鱼类健康及其环境的一种有价值的生物标志物。本综述重点介绍了作为一种重要的鱼类血液生物标志物的嗜碱性细胞增多症及其在了解鱼类健康和养殖条件方面的重要性。

Visualization of poikilocytosis as an emerging erythrocytic biomarker for fish health assessment

Fish health assessment is essential for maintaining sustainable aquatic ecosystems and ensuring the well-being of wild and farmed fish populations. Hematological parameters are crucial indicators of fish health, with poikilocytosis emerging as a fundamental marker with significant diagnostic value. Poikilocytosis refers to abnormally shaped erythrocytes in bloodstream, reflecting underlying physiological and pathological conditions. Poikilocytosis can occur in various fish species and can be influenced by environmental stressors, infectious agents, nutritional deficiencies, and exposure to pollutants. Morphological alterations in erythrocytes, such as acanthocytes, echinocytes, dacrocytes, schistocytes, spherocytes, and codocytes are common poikilocytes in fish. Understanding the relationship between poikilocytosis and fish health has important implications for disease diagnosis, monitoring, surveillance, and management. By quantifying poikilocytic changes, researchers and veterinarians can differentiate normal variations from pathological conditions, facilitating targeted interventions and treatment strategies. While most studies have focused on heavy metal toxicity, stressors, nutritional deficiencies, pollutants, and therapeutics, the etiological induction of poikilocytosis in fish health has been overlooked. Nonetheless, poikilocytosis remains a valuable biomarker for assessing fish health and their environment. This review highlights piscine poikilocytosis as a significant fish hematological biomarker and its importance in understanding their health and culture conditions.
