The osteological and myological structures of the cephalic region and pectoral girdle of the Asiatic catŽ sh Heteropneustes fossilis are described and compared with those of several other catŽ shes, as the foundation for an analysis on the phylogeneticrelationshipsof the genusHeteropneustes. Our observation and comparisons support a close relationship betweenHeteropneustesand the clariid catŽ s...

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 ...

background: this investigation describes the cyto-architectural alterations observed in the corpuscles of stannius of stinging catfish heteropneustes fossilis after treatment with a botanical pesticide nerium indicum. methods: heteropneustes fossilis were subjected to 11.27 and 2.81 mg/l of nerium indicum leaf extract over short- and long-term exposure periods, respectively. blood was collected...

Effect of Bisphenol A on the hematological parameters total RBC count, total WBC count and hemoglobin content was assessed in Heteropneustes fossilis caught from wild. Behavioural changes were also monitored. It was found that 72 hour exposure of BPA at a concentration of 0.1g/L has lowered total RBC count and increased WBC count. Hemoglobin concentration in the blood also decreased exposure to...

Photoperiod and temperature are well-established environmental cues for gonadal growth in seasonally reproducing organisms. The photoperiod is known to regulate seasonal reproduction via induction of thyroid hormone regulating genes the saccus vasculosus (SV) fishes. However, SV absent many breeding fishes, including Heteropneustes fossilis. H. fossilis a long-day catfish which recrudescence be...

Background: Previous studies have been reported on the toxicity of Microcystin-LR, which is produced by cyanobacterial growth in fish, such as Heteropneustes fossilis (H. fossilis). However, no studies have been conducted on the effects of Microcystin-LR on the prolactin cells of H. fossilis. Methods: H. fossilis fish were intraperitoneally injected with Microcystin-LR (2.5μg/25g) and sacrif...
