Pakistan Journal of Biological Sciences , 2001,
Abstract: Channa punctatus was exposed for 7days to sumithion at a concentration of 2.0, 5.0, 5.5, 10.0, 10.5, 15.0, 15.5, 18.5, 20.0, 20.5, 25.5 and 100ppm under laboratory conditions. The fish showed severe histological changes in liver, kidney and ovary tissues. The degenerative changes included hypertrophy of cells and their nuclei, liver cord disarray, vacuolation of the cytoplasm and necrosis. In some cells the membrane was ruptured. The liver on the whole showed distance appearance. Pycnosis, vacuolation, rupture of blood vessels and hematopoietic cells of kidney, fragmentation of ova were recorded in an increasing order towards the higher tested doses.

Ram P. Yadav,Digvijay Singh,S. K. Singh,Ajay Singh
Pakistan Journal of Biological Sciences , 2003,
Abstract: The exposure to fish over 96 h to sub-lethal doses 8.24 mg, DW L-1 and 16.48 mg, DW L -1 of stem-bark extracts of Croton tiglium of family Euphorbiaceae significantly altered the level of total protein, total free amino acids, nucleic acids, pyruvate, lactate, glycogen and activity of succinic dehydrogenase, lactic dehydrogenase, cytochrome oxidase, acetylcholinesterase, acid and alkaline phosphatase and protease activity in muscle, liver and gonadal tissue of fish Channa punctatus. The alteration in all the biochemical parameter was significantly dose dependent. Withdrawal study also shows that there is a partial recovery in the levels of glycogen, pyruvate, nucleic acids, acetylcholinesterase, cytochrome oxidase and acid and alkaline phosphatase, but nearly complete recovery in total protein, total free amino acids level and activity of protease, lactic dehydrogenase, succinic dehydrogenase and lactate in all the three tissues of the fish after the 7th day of the withdrawal of treatment, which supports the view that the plant product is safer in use as pesticides for control of common weed fishes in culture ponds.

Biology and Medicine , 2009,
Abstract: Almost all the pesticides and more particularly the synthetic pesticides used, find there way into water bodies alter themetabolism of aquatic organisms is known long back. In the present investigation, the effect of sub lethalconcentration of chlorpyrifos toxicity on fish Channa punctatus were studied after 24hrs, 48hrs, 72hrs and 96hrsexposure respectively. Chlorpyrifos is an organophosphate insecticide that kills insects by disrupting there nervoussystem and is effective against a wide range of plant eating insects. Suspected effects of chlorpyrifos exposureinclude birth defects, increased rate of leukemia and immune system abnormalities. The results indicated a significantincrease in ESR (mm/hr) 2.57mm/hr, 2.60mm/hr, 2.71mm/hr and 2.83mm/hr when compared to control group2.56mm/hr fallowing both acute and sub acute exposure of chlorpyrifos.

International Journal of Biomedical and Advance Research , 2012, DOI: 10.7439/ijbar.v3i11.784
Abstract: : Temperature of aquatic environment is important for ensuring the normal metabolism of aquatic animals. It also affects blood vascular system of aquatic organisms. The present paper deals with the influence of temperature on the hemoglobin content of freshwater fish, Channa punctatus. The freshwater fish, Channa punctatus, were collected from Godavari River, Nanded (Maharashtra). The fishes were exposed to different temperatures viz. 15°, 20°, 25°, 30°, 35° and 40° C. The total hemoglobin contents were observed at different temperature stress. The values were compared with the fish’s acclimated to ambient temperature. The haemoglobin content was found to be increased as temperature increases. The total hemoglobin content was found to be decreased as temperature decreases.

International Journal of Biomedical and Advance Research , 2013, DOI: 10.7439/ijbar.v3i12.788
Abstract: Out of various environmental factors that influence aquatic organisms, temperature is the most all-pervasive. The environmental temperature also affects blood vascular system of aquatic organisms. The present paper deals with the effect of temperature on the Erythrocyte Sedimentation Rate of freshwater fish, Channa punctatus. The freshwater fish, Channa punctatus, were collected from Godavari River, Nanded (Maharashtra). They were acclimated to laboratory condition. The fishes were exposed to different temperatures viz. 15°, 20°, 25°, 30°, 35° and 40° C. The sedimentation rate depends on the RBC count variations. The Erythrocyte Sedimentation Rate was observed at different temperature stress. The values were compared with the fish’s acclimated to ambient temperature. The Erythrocyte Sedimentation Rate was found to be increased when Channa punctatus acclimated to cold temperature stress. The sedimentation of erythrocytes was found to be decreased at warm temperature stress.
Effect of bioactive compounds extracted from euphorbious plants on hematological and biochemical parameters of Channa punctatus
Shahi, Jaya;Singh, Ajay;
Revista do Instituto de Medicina Tropical de S?o Paulo , 2011, DOI: 10.1590/S0036-46652011000500004
Abstract: channa punctatus was exposed to four different concentrations of rutin, taraxerol and apigenin. changes in some hematological parameters of channa punctatus were assessed to determine the influence of these compounds on test fish. fish were exposed to sublethal concentrations (80% of lc50 of 24h) of these compounds for one week. control fish were also administered for one week. thereafter, blood samples were obtained from the control and experimental fish. blood was assayed for selected hematological parameters (hematocrit, hemoglobin, red blood cell count, white blood cell count total plasma protein and plasma glucose concentration). the derived hematological indices of mean corpuscular hemoglobin concentration (mchc), mean corpuscular hemoglobin (mch) and mean corpuscular volume (mcv) were calculated. sublethal concentrations of these compounds caused a dose dependent decrease in hemoglobin values coupled with a decrease in hematocrit values and red blood cell counts are an obvious indication of anemia. the total white blood cell counts and the differential white blood cell counts were decreased except for the lymphocytes, where there was a slight increase. plasma protein and glucose were also lower in exposed fish when compared with control. the hematological indices mch, mchc, mcv were also lowered. the result from this study reveals high mortality rate and deleterious consequences on the health of fish subjected to acute exposure of rutin, taraxerol and apigenin and therefore, should not be used directly in aquaculture without having the proper knowledge.

Prof.R. N. Patil,Prof.U.S.Madnaik,prof. R.D.Bodare
Indian Streams Research Journal , 2012,
Abstract: he gill epithelial cells of Channa punctatus (Bloch) exposed to lethal concentration of malathion showed increased production of neutral mucins , sulfomucins and sialomucins in variable amount as compared to only neutral mucins in poor amount in control fish. Increase in the amount of only neutral mucins elaborated by M1 mucous cells and only sulfomucins by M2 mucous cells was also evident. The epithelial cells and mucous cells reaveled the absence of glycogen and any atypical mucosubstances both in control fish as well as in fishes exposed to pesticide.
Effect of Triazophos on Protein Metabolism in the Fish, Channa punctatus (Bloch)
Abdul Naveed,C. Janaiah
Current Research Journal of Biological Sciences , 2011,
Abstract: On treatment with sublethal dose of triazophos exposure i.e., 24, 48, 72 and 96 h on protein metabolism of fish Channa punctatus were observed. The harmful toxic effect of triazophos, is an Organo Phosphorus (OP), is investigated by measuring key enzymes in protein metabolism, Viz. catalases, Super Oxide Dismutase (SOD) and Xanthine Oxidase (XOD) and these antioxidant enzymes were altered. In the present investigations the activity of catalases reduced under toxicity because that triazophos initiates the enhancement of super oxide radicals. The inhibition of SOD activity in the fish reveals the impairment of antioxidant defense mechanism and also reduction in molecular oxygen and normal metabolism step. The decreased activity of XOD leads to increase in cellular damage through photolytic activity or non availability of iron under stress condition.
