“…Of these, the smaller has been called small lymphoid haemoblast and its development to mature erythrocytes has been traced. The large cells have been called large lymphoid haemoglasts and give rise to granulocytes (Mahajan & Dheer, 1980). The use of cytochemical techniques to differentially stain haemoglobin with Giemsa as counterstain, has facilitated the establishment of the developmental series in detail in the erythrocytes during this investigation, and is an advance over the ' histological study ' which limited Catton's work and made the developmental series somewhat hypothetical and sketchy.…”

Using spleen and head kidney imprints, studies on erythropoiesis in Channu punctntus have been made describing each developmental stage with regard to its morphology, morphometry and cytochemistry. This has been undertaken using the new techniques available for haematopoietic studies of fishes. These include autoradiography for information on DNA synthesis and Graham-Knoll's benzidine method with Giemsa used as a counterstain for the differential staining of haemoglobin. Thus, a more definitive picture of the haematopoietic phenomenon in Channa punctatus has been evolved.

“…The cells of the erythropoietic lineage were identi ed under an optical microscope (Olympus-BX41) according to Mahajan and Dheer (1980b) and Kulkeaw and Sugiyama (2012). The neutropoietic lineages were identi ed following Mahajan and Dheer (1980a) and Tak et al (2013). The relative abundance of the cells of the erythropoietic and neutropoietic lineage was calculated and presented in percent value.…”

Acacia auriculiformis pericarp preparation (APP) has been recently introduced as a piscicide of choice to substitute Mohua (Bassia latifolia) oil cake (MOC). The present study aims to evaluate its effect on circulatory physiology and haematopoiesis of Channa punctatus to justify its mode of action as a piscicide. Profound alterations in the circulatory physiology of Channa punctatus with oligocythemic hypochromic anaemia and significant mobilization of immature cells from the erythropoietic lineage into circulation are evident under APP exposure. A relationship of hypoxia-induced Epo expression with erythropoietic dynamics has been drawn under LC0 APP exposure. However, at both LC50 and LC100 exposure erythropoietic insufficiency and subsequent erythropenia are recorded. The principal secondary metabolite of APP, saponin is held responsible for membrane destabilization, pore formation, and several topographical alterations of erythrocytes. The exocytosis of haemoglobin is confirmed quantitatively and qualitatively. Retention of plasma Hb among the treated fish is substantiated through direct and indirect bilirubin content of blood and the physiological relevance of such condition has been interpreted. Leucocytosis and more specifically neutrocytosis at the initial exposure period observed as an immediate defensive mechanism which is ultimately broken down with exposure concentration and duration. The treated fish develops thrombocytosis as a haemostatic mechanism to check haemorrhage, but the circulatory deficiency ultimately leads to death of the fish.

“…Rao and Banerjee () reported that lymphocytes, neutrophils, monocytes, eosinophils and basophils are elevated at the time of EUS infection. Mahajan and Dheer () characterized the origin and development of murrel neutrophils and categorized into five stages: large lymphoid haemoblasts, promyelocytes, mesomyelocytes, metamyelocytes and mature neutrophils. Thus, it is clear that leucocytes and immunoglobulins play a key immune role against pathogens and toxins in C. striatus .…”

Channa striatus, also called snakehead murrel, is an important freshwater teleost fish which has been widely cultured for its tasty flesh along with nutritional and medicinal values. The growth of both cultured and wild murrels is affected by various physical, chemical and biological factors. As a teleost fish, C. striatus is an intermediate organism between invertebrates and vertebrates. They have a well‐developed innate immune system than invertebrates and a primitive adaptive immune system compared to that of higher vertebrates, thus an interesting unique immune structure to explore. Studies have identified that a few external stimulants do instigate the immune system to fight against the pathogens at the time of infection in C. striatus. This review discusses the physicochemical and biological stress factors, immune system and immune molecules of C. striatus which are potentially involved in combating the stress factors.
