Annotation:

Dioctyl phthalate (DOP) commonly used as plasticizer enters into aquatic environment from the industries manufacturing plastic products, PVC resins, cosmetics and many other commercial products. Therefore, this study was designed to evaluate the acute toxicity effects of Dioctyl phthalate on fresh water fish Clarias batrachus. The 96 hour LC50 of Dioctyl phthalate in Clarias batrachus was estimated as 14.5ml/L. Histopathological changes in liver of Clarias batrachus were determined by exposing them to a fraction of LC50(1/5th) dose with every change of water for 30 days.The liver of Clarias batrachus was excised at every interval of 30 days and histological changes of liver were studied under light microscopy. Liver tissues showed abnormalities. Centrilobular vacuolation, necrosis, eccentric nuclei and enlarged nuclei, Centrilobular degeneration of hepatocytes were observed in liver tissue of fish.

AbstractCannibalism is an important characteristic of African catfish that significantly reduces the number of stocked fish at harvest. This study evaluates the effect of reciprocal hybridization of Clarias batrachus and Clarias gariepinus on cannibalism and growth performance of their progenies in an indoor rearing system. The result obtained reveals excellent performance of hybrids of C. gariepinus ♂ and C. batrachus ♀ over the purebreds in terms of growth. However, the reciprocal hybrids between C. gariepinus ♀ and C. batrachus ♂ all died few hours after hatching. Cannibalism was significantly reduced in the crosses between C. gariepinus ♂ and C. batrachus ♀ with 100% survival after five months of culture. Hence, this could be exploited in commercial production of catfish to reduce cannibalism and increase harvest size of fish farmers.

Annotation:

Catfish (Clarias batrachus) oil contain the highest amount of omega-3-PUFA among other freshwater fish. The omega-3-PUFA in fish oil produced eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA). It is known that EPA and DHA in essentials fatty acid (EFA) could improve BMP-2 expression. Bone morphogenetic protein-2 (BMP-2) is bone stimulator which capable of inducing differentiation of mesenchymal cells into osteoblast, stimulating bone formation in wound healing process of dental extraction. Purpose: To prove the increasing expression of BMP-2 after catfish (Clarias batrachus) oil application. Methods: We have used the post test only design in this research. There have been 21 Rattus novergicus as research samples, and those were divided into 3 groups, group KK as control, group KP1 was given catfish (Clarias batrachus) oil in 5% concentration, and group KP2 was given catfish (Clarias batrachus) oil in 10% concentration. Catfish (Clarias batrachus) oil were applied into the socket of dental extraction. Rat was decapulated 7 days after fish oil application and the jaw in the treated regions and control group were cut for immunohistochemistry examination to observe BMP-2 expression. Data was analyzed using one-way ANOVA test. Result: There is significant difference increased of BMP-2 expression between control and treatment group. In samples given with 10% concentration of catfish oil had the most significant increase of BMP-2 expression. Conclusion: Catfish (Clarias batrachus) oil in 10% concentration could increase the expression of BMP-2 post dental extraction.Key words: Catfish oil, BMP-2, dental extraction.

Antibiotics and several other chemicals are used in catfish aquaculture as a remedy for various diseases. Reports on the distribution of different groups of bacteria especially the antibiotic resistant bacteria in catfish nursery system are scanty. The present study quantified motile aeromonads, pseudomonads and antibiotic (oxytetracycline) resistant bacteria in Clarias gariepinus and C. batrachus larvae and the rearing water from five catfish nurseries of West Bengal, India between March 2007 and July 2007. The C. gariepinus and C. batrachus larvae recorded mean counts of log 7.26±0.18/g and log 6.24±0.64/g, log 6.37±0.41/g and log 4.93±0.51/g, log 5.46±0.22/g and log 4.38±0.53/g and, log 6.27±0.64/g and log 5.57±0.12/g, respectively for total viable bacteria (TVCs), motile aeromonads (MACs), presumptive pseudomonads (PPCs) and oxytetracycline resistant bacteria (ARBCs). The levels of TVCs, MACs, PPCs and ARBCs were significantly high in C. gariepinus than in C. batrachus larvae. The rearing water recorded comparatively low bacterial counts than in larvae. The difference between the TVCs of larvae and larval rearing water of C. gariepinus was statistically significant, where as it was insignificant for C. batrachus. The mean proportion of motile aeromonads of C. gariepinus larvae and rearing water was about 4-5 fold higher than in C. batrachus.

Annotation:

Acephate is an insecticide made up of organophosphates. It is applied to food crops, citrus trees, on golf courses, in commercial or institutional buildings, and as a seed treatment. Products containing acephate can be purchased as tablets, liquids, granules, powders, and water-soluble packs. Acephate 75% brand name-Asataf insecticide manufactured by TATA RALLIS was used for the test. The solvent used was glass double distilled (g.d.d.) water. Fresh water catfish Clarias batrachus were collected from local water bodies of Cuttack district. All the fishes were acclimatized for fifteen days in laboratory aquaria containing 30L dechlorinated tap water prior to the initiation of the experiment. The peripheral blood smear slides were prepared from the blood collected by caudal incision in accordance with Al-Sabti (1986) and Das and Nanda (1986) with some modifications which were prepared animals were sacrificed after 24, 48 and 72 hours of Exposure and were used for each treatment group in both types of administrations (IP and dermal). The increased concentration of acephate directly affects our biological fish sample i.e. Clarias batrachus. Acephate is causing serious problems in fish as per our genotoxicity study of acephate on Clarias batrachus. Clarias batrachus is a commonly found fish species in fresh water habitat which includes ponds, ditches, wetlands and rice fields of India specially in Odisha.The irrational use of pesticides containing acephate in agriculture cause harmful effects on Clarias batrachus, which is a most important species of fish for maintaining the aquatic diversity.

Annotation:

Two catfish: Clarias batrachus (Linnaeus) and C. gariepinus (Burchell) were selected for examination during June, 2014 to May, 2016. The percentage (g/100 g) of nutrients such as moisture, ash, fat, protein, carbohydrate contents (mg/100 g) and energy (K cal) in C. batrachus and C. gariepinus was determined. Analyses were done to measure the nutrition value of edible body parts (flesh) of C. batrachus and C. gariepinus. The effects of modifying factors such as, season, sex, length, and diet of the hosts on the abundance of parasites were also studied. Present observation on biochemical analysis showed small variation in nutrient contents between C. batrachus and C. gariepinus. Protein, fat, moisture, carbohydrate levels were higher in non-infected C. batrachus (moisture 78.25 ± 0.06 g/100 g, ash 1.42 ± 0.09 g/100 g, fat 1.20 ± 0.04 g/100 g, protein15.05 ± 0.19 g/100 g, carbohydrate 5.53%) and non-infected C. gariepinus (moisture 78.62 ± 0.01 g/100 g, ash 1.22 ± 0.10 g/100 g, fat 1.19 ± 0.03 g/100 g, protein 14.69 ± 0.07 g/100 g, carbohydrate 4.95% than those of infected C. batrachus and C. gariepinus. In both species the highest presence of most of the nutrient components was observed in winter. Bangladesh J. Zool. 47(1): 27-39, 2019

αB-crystallin,shown to be a member of the small heat-shock protein( sHSP )family,is synthesized at various developmental stages,especially in response to stress and in a number of pathological states. Clonging and Northern analysis show unambiguously that αB-crystallin mRNA is present in some mature tissues of the walking catfish(Clarias batrachus),although there are some differences in the transcription pattern. Interestingly,sequence analysis has shown that walking catfish αB-crystallin exists as a shortened gene both in cDNA and genomic structure despite its being similar to sHSP as other mammalian αB-crystallins. We have prepared anti-walking catfishαB and αA antiserum,and use them for Western-blot analysis of α-crystallin from various species to study the immunological specificity and relationship. In this study,we have found some differences in the chaperone activity of walking catfish and porcine α-crystallins,which may reflect the structural differences as revealed by the shortened primary sequence in the walking catfish as compared to mammalian αB-crystallins.
