In the present study on characterization and identification of lipids by thin layer chromatography in different tissues of Heteropneustes fossilis showed a considerable variation. The number of lipid spots was highest in brain compared to other tissues. The Rf values of spots indicate the regions of similarity between tissues. Comparison of Rf values with those of standards indicated that the presence of phospholipids, choline lipids, gyolopids, ninhydrine, amino group containing lipids were present. Intestine showed more amount of glycolipids and low amount of ninhydrine containing lipids, While liver possessed Iodine containing lipids.in addition these, whereas brain showed glycolipids, ninhydrine containing lipids, Iodine containing lipids and choline lipids too. The present study revealed that the Brain contain highest amount of different classes of lipids. The Liver tissue has shown less number of lipids. Glycolipids and general class of lipids are present in all tissues with minor variations, choline lipids present in brain but not in remaining tissues, while Phospho lipids are present in intestine and brain only, whereas amino group containing lipids were more in all tissues when compared with other class of lipids.

Annotation:

Effects of endoparasitism of Heteropneustes fossilis on condition factor, gonad and blood composition of the host was conducted during July 2012 to June 2013. Fish samples were collected from various water bodies of Sylhet region. Total length, body weight, gonad weight and sex of hosts were recorded. Blood sample was collected from each fish. Six different species of parasites were identified from the hosts assessed as i). Euclinostomum multicaecum, ii) Allocreadium handiai, iii). Lytocestus indicus, iv). Pseudocaryophyllaeus heteropneustus, v). Procamallanus heteropneustus and vi). Paracamallanus equispiculus. Gonad weight, condition factors and blood parameters of H. fossilis were greatly affected with moderate infestations. The highest condition factor, 0.59, was found in uninfested fish and lowest, 0.45, in infested fish. Changes in the percent of haemoglobin and erythrocyte sedimentation rate (ESR) was also investigated. Percent loss of haemoglobin was 0.43 and erythrocyte sedimentation rate (ESR) was 5.19 mm/h. In general the health condition parameter due to effects of endoparasitism of the investigated fish was found negative impact for the culture production of the Singhi (Heteropneustes fossilis).

Annotation:

The freshwater Stinging catfish locally known as Shingi (Heteropneustes fossilis) is exposed to various concentrations of analytical grade FeSO4.7H2O. The LC50 values for Fe2+ were found to be 109, 68 and 45 mg/l at 24, 48 and 72 hrs, respectively indicating that the toxicity increased with time. Gills appear to be the first target organ for iron toxicity followed by the liver and muscle. Moisture contents in fish tissue increased due to release of the toxicant by biological way. Protein and lipid contents are decreased and ash content is increased with the increase of exposure time. In contrast, iron is relatively nontoxic to Shingi fish at low dose, but long time exposure has adverse effects in fish tissue. Thus, exposure to iron salt at toxic level resulted in accumulation of iron in fish tissue. Hence, the consumption of this type of contaminated fish might have detremental effect on human health. However, this needs extensive study to make any final conclusion.Bangladesh Pharmaceutical Journal 18(2): 179-182, 2015

Background: The physiological conditions of fish are essential for the successful fish culture. Objective: The purpose of the present study was to see the haematological parameter of air breathing cat fish (Heteropneustes fossilis) of Bangladesh. Methodology: This animal study was conducted in the Bargen lab in the Department of Zoology at University of Dhaka as well as in The Peoples Pathological lab which was a private diagnostic laboratory at Dhaka city from July 2008 to April 2009 for a period of 9(nine) months. The fish was Heteropneustes fossilis. Haemocytometer including two graduated pipettes was used for counting leucocytes. Result: The result indicated eight types of blood cells in peripheral condition of Heteropneustes fossilis. The average cellular counts of Heteropneustes fossilis were erythrocytes 8.45´106 m3, leukocytes 15.44´103m-3, Thrombocytes 34.72%, large lymphocytes 1.02%, small lymphocytes 26.7%, monocyte 3.9%, neutrophil 16.9%, eosinophils 6.97%, basophiles 8.6%, haemoglobin 11.7g 100ml1, erythrocyte sedimentation rate (ESR) 6.49g 100ml-1. The most of the hematological parameter showed intra specific variation except eosinophils and ESR of Heteropneustes fossilis (Shing fish). Conclusion: Hematological studies shows that the physiology of fish change with the change in the environment, time, season, maturity, nutritional state, activity level physical and chemical change in water.DOI: http://dx.doi.org/10.3329/jsf.v11i1.19398

AbstractThe osteological and myological structures of the cephalic region and pectoral girdle of the Asiatic catfish Heteropneustes fossilis are described and compared with those of several other catfishes, as the foundation for an analysis on the phylogenetic relationships of the genus Heteropneustes. Our observation and comparisons support a close relationship between Heteropneustes and the clariid catfishes. More specifically, the present study supports De Pinna's 1993 study, according to which Horaglanis and Uegitglanis, two genera commonly included in the family Clariidae, are the successive sister-groups of a monophyletic clade composed by the genus Heteropneustes and the remaining clariid genera.

The aim of present study was to determine the toxicity (LC50) of cadmium chloride in freshwater catfish Heteropneustes fossilis. Acute toxicity of cadmium on the indigenous fish H., fossilis was designed in the fish aquarium in laboratory at room temperature in Department of Zoology, DGPG College at Kanpur.Treated fish H., fossilis induced morphological alteration against cadmium chloride toxicity. H. fossilis showed morphological alteration such as increased opercula movement, abnormal swimming, and loss of buoyancy and fading of their body colour. Control fishes were also continuously monitored and compared with the changes caused by cadmium concentration. Heteropneustes fossilis exposed different concentration of cadmium chloride toxicity i.e. 0 ppm for 24 h, 10 ppm for 48h, 15ppm for 72h and 20 ppm for 96 h. From this present study it seems that the indigenous fish, H. fossilis is more susceptible to cadmium toxicity.

Annotation:

Octavolateral area is a significant component of rhombencephalon in teleosts which shows afine cytoarchitecture and comprises many intermingled nuclear groups. In the present study,distribution pattern of enzyme acetylcholinesterase has been carried out by employing amodified histochemical technique to visualize acetylcholine containing neurons described byHedreen, J.C. et.al. (1985).Acetylcholinesterase is an effective marker of cholinergic-cholinoceptive neurons since ithydrolyses acetylcholine in to choline and acetate at synaptic clefts. Present histochemicalresults exhibited a widespread distribution of acetylcholinesterase in the different nuclei ofoctavolateral area of Heteropneustes. Octavolateral efferent nucleus, medial octavolateralnucleus, magnocellular and posterior octaval nucleus demonstrated intense activity foracetylcholinesterase, while anterior octavolateral nucleus and descending octaval nucleusexhibited moderate staining. The distribution of acetylcholinesterase was homogenous in thewhole rostro-caudal and lateral extension of this nucleus.Thus in overall picture, octavolateral nucleus contains abundant cholinergic cells in the brainof Heteropneustes. In conclusion, the abundance of cholinergic innervations in this area is awell conserved characteristic among vertebrates which has been discussed from phylogeneticperspective.

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 sacrificed after 1, 3, 5, 10 and 15 days. The blood samples were analyzed for the calcium levels. Histological slides of the pituitary prolactin cells were stained with Herlant’s tetrachrome and Heidenhan’s azan techniques, and examined under light microscopy. Results: The prolactin cells exposed to Microcystin-LR exhibited no structural changes on day 1. However, hyperactive prolactin cells exhibited cellular degranulation from day 3 to day 5. On days 10 and 15, degenerated and vacuolated prolactin cells were also observed. The nuclear volume of prolactin cells exposed to MC-LR increased progressively from day 3 to day 10 but on day 15 the nuclear volume returned to normal. The serum calcium level of MC-LR injected specimens showed hypocalcemia from day 3 to day 10. On day 15, the level became normal. Conclusions: Our results indicated that the serum calcium levels and prolactin cells were altered after exposure to microcystin-LR.

Effects of different chemotherapeutics were examined against experimentally infected stinging catfish Heteropneustes fossilis. Fish were collected from a fish market in Mymensingh, acclimatized for 7 days in laboratory condition from January to February, 2016 in aquaria at Fish Clinic of Bangladesh Agricultural University, Mymensingh, experimentally injured by using forceps and knife and waited seven days for the establishment of infection. Before starting chemotherapeutic trial, it was confirmed that the fish were infected with microorganisms by clinical diagnosis in laboratory condition. They showed hemorrhages and ulcerative lesions over the infected area. A total of 80 such experimentally infected stinging catfish having average body weight of 18 g were used for the experiment. Two chemotherapeutics: antibiotic, Eryvet (erythromycin thiocyanate INN, sulphadiazine (NaUSP) & trimithoprim BP) and antifungal, methylene blue were used in separate and combined treatment with three different doses of antibiotic. The same dose of methylene blue, 0.2 mg/l, was used for separate and combined treatment by antibiotic. Doses of antibiotic (Eryvet) were 0.8 g/10 kg body weight of fish, 1g/10 kg body weight of fish and 1.2 g/10 kg body weight of fish as lower dose, recommended dose and higher dose respectively. For combined treatment the above different doses of antibiotic and the same dose of antifungal were used. Water was exchanged regularly. The chemotherapeutic trial was conducted for 7 days and observation was continued for another 8 days to observe the effect of treatment. Combined treatment with the recommended dose of the antibiotic and methylene blue showed the best result where 90% fish were recovered. By the treatment with the higher dose of the antibiotic 70% fish were recovered. Antifungal treatment showed that 20% fish were recovered. All the fish in negative control aquarium died.Asian J. Med.

SummaryDetermination of optimum sperm requirement in artificial breeding helps to improve the fertilization efficiency, sperm economy and minimize the sacrificing of males for milt. Quantification of sperm cells was done by spectrophotometer at 420 nm followed by haemocytometer counting. Best correlation (r2 = 0.97) was recorded. The minimum number of sperm required for optimal fertilization success in Heteropneustes fossilis was determined. An average fertilization success of 78–93% was recorded at 8 × 103 to 8 × 107 sperm per egg. The optimum contact duration of gametes was 5 minutes. The highest fertilization rate of 98.18% was recorded at 8 × 107 spermatozoa.egg−1.

The study was conducted to prepare a database for the infection status of protozoan parasites on an important host fish species of Bangladesh, Heretropneustes fossilis. Host samples were collected from the freshwater habitats of six different districts of Bangladesh- Manikganj, Faridpur, Mymensingh, Kishoreganj, Bogura, and Jashore. H. fossilis was noted to be infected by 6 parasite species, of which 3 belonged to myxozoa (Henneguya singhi, Henneguya qadrii and Henneguya mystusia); 1 belonged to ciliophora (Trichodina siddiquae) and 2 (Trypanosoma singhii and Piscinoodium pillulare) belonged to mastigophora.The parasites, Trypanosoma singhii and Henneguya singhi were recorded as new locality record in H. fossilis. The three parasites Piscinoodium pillulare, Henneguya qadrii and Henneguya mystusia were the first recorded parasites in this fish and the first locality record in Bangladesh. The parasites were observed to occupy gill, body slime, and blood. Gill parasites were abundantly found compared to body slime and blood parasites. The highest prevalence (67.21%) of infection of H. fossilis was observed in Manikganj and the lowest prevalence (54.67%) of infection was observed in Bogura. Parasites of H. fossilis showed the highest diversity in fishes of Faridpur (2.63). Species richness of parasites was highest in Manikganj (0.38) and species evenness was relatively low (0.13-0.19) in almost all the study sites. Dhaka Univ. J. Biol. Sci. 30(2): 307-316, 2021 (July)

Mass mortality of fish was observed in the morning on 02-02-2011 in winter monomictic Surinsar lake, Jammu and has been reported. Maximum count of dead fish was shared by Puntius spp. (P. ticto, P. conchonius and P. sophore). Other dead fishes of family Cyprinidae include Rasbora rasbora, Esomus danrica and Cyprinus carpio communis. A few dead specimens of air breathing Heteropneustes fossilis and Channa punctatus were also seen. In the present paper, possible causes of fish kill have been described.

Abstract The present study was designed to assess the adverse effects of the agrochemical Almix on comparative basis in gill, liver and kidney of Heteropneustes fossilis through histological and ultrastructural observations under field (8 g/acre) and laboratory (66.67 mg/L) conditions. Exposure duration of both experiments was 30 days. Gill showed atrophy in secondary lamellae, hypertrophied gill epithelium, damage in chloride and pillar cells, and detachment of chloride cells from gill epithelium under laboratory condition, but hypertrophy in gill epithelium and fusion in secondary lamellae were seen under field condition. In gill, scanning electron microscopy (SEM) showed fragmentation in microridges, hyper-secretion of mucus and loss of normal array in microridges, while transmission electron microscopy (TEM) displayed dilated mitochondria and rough endoplasmic reticulum (RER), abnormal sized vacuolation in chloride cells under laboratory condition. In liver, hypertrophied and pyknotic nuclei, disarrangement of hepatic cords, and cytoplasmic vacuolation were prominent under laboratory study but in field condition the liver showed little alterations. TEM study showed severe degeneration in RER and mitochondria and cytoplasmic vacuolation under laboratory condition but dilated mitochondria were prominent in field observation. Kidney showed severe nephropathic effects including degenerative changes in proximal and distal convolute tubule, damage in glomerulus under light microscopy, while deformity in nucleus, fragmentation in RER, severe vacuolation and necrosis in kidney were prominent under TEM study. The results clearly demonstrated that responses were more prominent in laboratory than field study. Thus the responses displayed by different tissues of concerned fish species exposed to Almix could be considered as indications of herbicide toxicity in aquatic ecosystem.
