Abstract

Detailed accounts supported by experimental data are furnished regarding the haematological parameters of the host fish, Channa striatus infested by the isopod, Alitropus typus. Results demonstrate that the infested fish become anaemic through loss of blood as shown by a reduction in the total erythrocyte count, haemoglobin content and haematocrit. Considering the mean corpuscular volume, mean corpuscular haemoglobin, mean corpuscular haemoglobin concentration and volume index, the anaemia can be designated as macrocytic and hypochromic. The total and differential counts of white blood corpuscles of the infested fish indicate leucopenia coupled with lymphocytosis. The percentages of monocytes, neutrophils and macrophages, which were 0.65%, 0.39% and 1.04%, respectively, after 24 h of infestation, had increased to 2.31%, 4.91% and 2.02%, respectively, after 96 h of infestation and declined thereafter.

Despite these variables, haematological indices can be an effective method for assessing the health of fish and monitoring physiological and pathological changes given that the haematopoietic system plays an integral role in normal biology and immunity. For example, changes in leucocytes are apparent with a range of infectious agents, such as parasites (Nair and Nair, 1983; Ruane et al., 2000), bacterial infections (Hine, 1992; Silveira-Coffigny et al., 2004), and viral infections (Novoa et al., 1995). Other environmental insults also lead to haematological changes in fish, including acute Cu2+ exposure (Mazon et al., 2002; Nussey et al., 1995; Svobodová et al., 1994) and pesticides (Ek et al., 2003; Satyanarayan et al., 2004).
Chronic ulcerative dermatopathy (CUD) is a disfiguring condition affecting Murray cod cultured in untreated groundwater. This study sought to further investigate the possible etiology of the syndrome and determine whether groundwater pre-treatment could suppress the development of CUD in juvenile Murray cod. Electrolyte enrichment or pre-treatment with UV irradiation delayed the onset of CUD. In contrast, pre-conditioning of groundwater either in a vegetated earthen pond or in the presence of artificial macrophytes drastically reduced both the incidence and severity of CUD, with more than 90% of fish exhibiting no visual signs. Haematology and blood parameters were assessed for future diagnostic potential, but no changes in blood parameters were observed, even in advanced CUD-affected fish. This paper identified that the treatment of groundwater via an earthen pond and in the presence of an artificial macrophyte are two highly effective methods of preventing CUD arising in juvenile Murray cod.

Citation Excerpt :
The presence of immature erythrocytes in circulation does not always signify a regenerative anemia; immature cells may be present in response to environmental stressors, such as hypoxia, toxins, or temperature change [18,25–27]. Hemorrhagic anemia in fish may be associated with trauma, cutaneous ulceration, parasitism (lampreys, leeches, and isopods) [5,28], nutritional deficiencies (vitamin K and B, inositol, and choline) [5,18], and viral or bacterial septicemia (Tables 1 and 2). When severe or chronic blood loss occurs, the net loss of iron may result in iron deficiency anemia.
Hematology can be a useful tool for monitoring health status, detecting illness, and following the progress of disease and response to therapy. Despite advances in fish medicine in recent years, interpretation of fish hematology often is hampered by a lack of meaningful reference values and the bewildering diversity of fish species. A multitude of intrinsic and extrinsic factors cause normal and abnormal variation in hematologic data. This article provides an overview of some of the hematologic abnormalities in fish induced by infectious agents and environmental, husbandry, and nutritional issues.
