Effects of lead nitrate on histo-cytological alterations of corpuscles of Stannius of stinging catfish, Heteropneustes fossilis
Background: The present study investigated the effects of lead nitrate on the histo-cytological changes in the corpuscles of Stannius (CS) of Heteropneustes fossilis. Methods: Catfish, Heteropneustes fossilis were subjected to 657.6 mg/L and 164.4 mg/L of lead nitrate for 96 h and 28 days, respectively. Blood from fish was collected on 24, 48, 72 and 96 h in short-term and after 7, 14, 21, an...
متن کاملMicrocystin-lr Attenuates Blood Calcium and Phosphate Levels in Stinging Catfish Heteropneustes Fossilis
The present study was aimed to investigate the effects of microcystin–LR (MCLR) on the blood electrolytes of Heteropneustes fossilis. The fish were injected microcystinLR (2.5 μg/25 g) intraperitoneally at the initiation of the experiment. Blood samples were collected and the serum calcium and phosphate levels were estimated at 1, 3, 5, 10, 15 days. There is no change in serum calcium level of ...
متن کاملDose- and time-dependent micronucleus induction in peripheral erythrocytes of catfish, Heteropneustes fossilis (Bloch) by zinc
As far as the detection of metal genotoxicity in fish is concerned, micronucleus (MN) test is considered an extremely suitable measure. In this study, frequencies of micronucleated erythrocytes were scored in peripheral blood of catfish, Heteropneustes fossilis (bloch) after acute in-vivo exposure of zinc at different concentrations (5, 10 and 30 ppm) in the laboratory condition. These three co...
متن کاملEvaluations of Body Composition and Growth Performance by Applying Different Dietary Vitamin C Levels in Stinging Catfish, Heteropneustes Fossilis
An experiment was conducted for sixty days to evaluate the effects of Vitamin C of formulated feed on growth performance and body composition of stringing fish, Heteropneustes fossilis (Bloch, 1792). During experimental trial in the laboratory condition, the change in growth and feed utilization by the stringing fish fed on three different Vitamin C level have been assessed by the determination...
متن کاملEffect of Oxygen Management on Culture Performance of Channel Catfish in Earthen Ponds
—Aeration allows for higher feeding rates and increased production of channel catfish Ictalurus punctatus in intensive and semi-intensive aquaculture systems. However, the effect of specific dissolved oxygen (DO) concentrations on various production parameters remains unknown. The purpose of this 2-year study was to determine the effect of daily minimum DO concentration on channel catfish produ...
