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.

Abstract: Malathion is an organophosphorous insecticide widely used in agricultural and non agricultural purposes in India, creates a serious threat to the environment as well as target and non target organisms. The present investigation was undertaken to study the effect of malathion on some haematological parameters of Channa punctatus. Channa punctatus was treated with malathion and LC50 value for 96 hours was calculated following probit analysis methods. Channa punctatus was exposed to sublethal concentration of malathion (0.8 ppm). The study revealed a declining trend of RBC, Haemoglobin and increasing trend of WBC indicated toxic effect of malathion on Channa punctatus.

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.

British Journal of Pharmacology and Toxicology , 2011,
Abstract: The blood of fresh water, edible fish, Channa punctatus (=murrel) was exposed to sub lethal concentration of triazophos for 24, 48, 72 and 96 h to evaluate alterations in the levels of minerals i.e., sodium, potassium, chloride, calcium, inorganic phosphate, magnesium and iron. The increased chloride mineral along with sodium and potassium play an important role in neuromuscular excitability, acid-base balance and increased osmotic pressure of the fish. The decreased calcium is of great importance in blood coagulation, muscle contraction and nerve transmission while decreased iron is an essential constituent of heame in hemoglobin of the fish. The increased magnesium participates in principal metabolic activities, in formation of bones and teeth. Inorganic phosphate acts as a major buffer and is the basis of energy exchange. Triazophos altered the activities of the macro minerals in C. punctatus during stress periods.

Abstract: In the present investigation, the effect of sub lethal concentration of the garlic aqueous extract on fish Channa punctatus were studied after 24 hrs, 48 hrs, 72 hrs and 96 hrs exposure respectively. Different concentrations of garlic (10 ppm/lit, 15 ppm/lit) used against Protein contentof fish and results showed the gradual decrease in the protein content, ranging (106.14 – 91.65 mg/gm) for 10 ppm/lit for (24 hrs – 96 hrs) and (103.90 - 88.13 mg/gm) for 15 ppm/lit respectively.

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.
Effect of Triazophos on Protein Metabolism in the Fish, Channa punctatus (Bloch)  [cached]
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.

Journal of Applied Sciences in Environmental Sanitation , 2012,
Abstract: Stress response of aluminium (Al2(SO4)3) toxicity on fish Channa punctatus Bloch has been evaluated via standard stress indicators. The primary stress response in the form of elevated cortisol was evident within 24 hours. The rise of cortisol level was about 170% and it persisted for the next 24 hours. The toxicity also evoked secondary response in the form of increased plasma glucose and C-reactive protein but only after 48 hours of eposure. These stress indicators are very conspicuous and since stress is an energy demanding process hence it is believed that aluminium toxicity has initiated the cortisol release which is responsible for mobilization of glucose from the liver to cope with the stress. The increase in C-reactive protein is an evidence of tissue injuries as a consequence of acute aluminium toxicity.

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.

Abstract: adult channa punctatus murrels of both sexes (60-80 g) were collected locally from ramgarh lake during the second week of every month (10 individuals of each sex/month) throughout the year. blood samples were collected and analyzed for serum calcium and phosphate levels by the methods of trinder (1960) and fiske and subbarow (1925), respectively. gonads were fixed to judge the state of maturation of the fish. males exhibited no change in serum calcium levels throughout the year in correlation with testicular maturation. however, serum phosphate levels exhibited a rise in correlation with the increased gonadosomatic index. females showed marked seasonal changes in serum calcium and phosphate levels which were associated with ovarian maturation (vitellogenesis).
