Literature reviews of all references concerning the parasitic fauna of fishes in fish farms of Babylon province, middle of Iraq, showed that a total of 92 valid parasite species are so far known from the common carp (Cyprinus carpio), the grass carp (Ctenopharyngodon idella), and the silver carp (Hypophthalmichthys molitrix) as well as from three freshwater fish species (Carassius auratus, Liza...

The study was conducted to identify the protozoan parasites in a freshwater indigenous air breathing fish, Heteropneustes fossilis (Bloch, 1794). host fish collected during mid of April 2018 end March 2019 from bodies Mymensingh, Kishoregonj, Faridpur, Jashore, Manikganj and Bogura districts Bangladesh. Three species phylum myxozoa namely Henneguya singhi, qadrii, mystusia, one ciliophora Trich...

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, and ...

Microcystin is a toxin secreted by cyanobacteria, which are the dominant phytoplankton in eutrophic freshwater bodies. The present study reports histopathological, hematological and biochemical changes in the freshwater fish, Heteropneustes fossilis due to toxicity of microcystin. Toxic effects were observed in liver, kidney, corpuscles of Stannius, gills and gonads. Bilirubin concentration inc...

Fresh water fish, Heteropneustes fossilis were subjected to 5.76 μg/L (0.8 of 96 h 50% lethal concentration, LC50) and 1.44 μg/L (0.2 of 96 h LC50) solution of cypermethrin for short-term (96 h) and long-term (28 days), respectively. After short-term cypermethrin exposure, the plasma calcium levels of Heteropneustes fossilis showed a decrease which persisted for 96 h. In long-term exposed fish,...

Aquaporins (AQPs) are membrane channel proteins which facilitate the rapid transport of water across cellular membrane and are of fundamental importance to the control of cell volume and transcellular water traffic. In the present study using bioinformatic tools an in silico modeling and analysis of aquaporin protein sequences of catfish Heteropneustes fossilis was conducted. Primary structure ...

Static renewal evaluation of the acute toxicity of an organophosphate pesticide, dimethoate against the freshwater fish H. fossilis was conducted in the laboratory. H. fossilis showed behavioural changes against dimethoate intoxication. There were increased opercular movement, sluggish, lethargic and abnormal swimming, loss of buoyancy and muscular tetany. The treated fishes also showed fading ...

The development of the nematode Procamallanus saccobranchi Karve, 1952, a parasite in the stomach of the fish Heteropneustes fossilis (Bloch), was studied in Mesocyclops crassus (Fischer) and Mesocyclops leuckarti (Claus). After being ingested by the copepods the nematode first-stage larvae penetrated into the haemocoel of the intermediate host; there they moulted twice (on days 3 and 5 p.i. at...
