Estimation of Acute Toxicity of Chromium to the Freshwater Catfish Clarias batrachus (Linn.)
Anthropogenic activities has increased the discharge of various concentrations of both essential and nonessential metals into aquatic ecosystems. The present study has been conducted to determine the median lethal concentration of chromium to the freshwater fish Clarias batrachus following standard procedures and was found that 40.56ppm, 38.15ppm, 36.65 ppm and 35.50ppm for 24h, 48h, 72h and 96...
متن کاملAluminium toxicity induced poikilocytosis in an air-breathing teleost, Clarias batrachus (Linn.).
The present study was undertaken to assess the toxicity of acid alone and two different sublethal concentrations of aluminium, (25% and 75% dose of 96 hr LC50 value in acidified soft water of pH 5) on red blood cells of a stenohaline catfish, C. batrachus for an acute exposure of 5 days. The scanning electron microscopic studies on all the three treated groups revealed several kinds of erythroc...
متن کاملANTIBIOTIC RESISTANT MOTILE AEROMONADS INDUCED SEPTICEMIA IN PHILIPPINE CATFISH Clarias batrachus (Linnaeus, 1758) FINGERLINGS
Philippine catfish, Clarias batrachus farming is receiving much attention in recent years so also the diseases in catfish aquaculture. During the disease surveillance in catfish farms, mortalities were observed in C. batrachus fingerlings in a nursery and this report describes the bacteriological and histopathological observations made on the diseased catfish. The gross and clinical signs obser...
متن کاملRole of thyroidal and testicular hormones in regulation of tissue respiration in male air-breathing fish, Clarias batrachus (Linn.).
In vivo and in vitro effects of thyroidal hormones (MIT, DIT, T3, T4), propyl thiouracil (PTU), testosterone and cyproterone acetate were studied on the rate of tissue (liver, muscle, kidney and brain) respiration of adult male C. batrachus during winter and summer/rainy seasons. Monoiodotyrosine (MIT) and diiodothyrosine (DIT) increased the respiratory rate in a dose-dependent and temperature-...
متن کاملAir-breathing rhythm in Clarias batrachus (Linn.): modulatory role of eyes, pineal and exogenous melatonin.
Effects of enucleation followed by pinealectomy and administration of exogenous melatonin on air-breathing activity rhythm in a fresh water catfish, C. batrachus maintained at LD 12:12 and laboratary temperature during its prepratory phase, were examined. Results of cosinor analysis clearly reveal that most of the intact individuals exhibited circadian rhythm in their air-breathing activity and...
