fed to farm cats, which are major reservoir hosts for fishborne liver and intestinal trematodes. Infections (prevalence 8.3%) in snakehead fish (Channa spp.) also represent a food safety risk, because snakehead fish are cultured in Vietnam and are sometimes eaten raw or inadequately cooked. In addition to O. viverrini flukes, metacercariae of the zoonotic intestinal flukes Centrocestus formosan...

In the present study, an attempt has been made to examine the toxic effect of cypermethrin, a synthetic pyrethroid exposed to freshwater fish Channa punctatus. The fishes were exposed to sublethal concentration of 0.08 mg/L for 15, 30 and 45 days. The gills of the fish plays vital role in respiration and are an important organ with specific functions which are highly sensitive to many factors. ...

The in vivo genotoxic potential of Stomp Xtra herbicides was evaluated in a freshwater fish Channa punctatus by assessing mitotic index in the kidney cells and micronuclei in the peripheral blood cells. Fish were exposed to five sub-lethal concentrations of Stomp Xtra containing a.i. pendemethalin at 0.293 (10% of LC50), 0.587 (20% of LC50), 0.881 (30% of LC50), 1.174 (40% of LC50) and 1.468 (5...

Three different concentrations of clove oil were applied to two different size groups of singhi (Heteropneustes fossilis) and lata (Channa punctatus) fish to observe the anaesthetic effect and to find an optimum dose. Two groups each consisting of 10 fish was exposed to 0.01, 0.02 and 0.03% clove oil. All fish of either size anaesthetized with 0.01% clove oil exhibited longer induction and shor...

The purpose of this study was to assess the water qualities and genotoxicity of Maheshara Lake situated near Gorakhpur, India. The lake receives many types of pollutants from two industries, agricultural run-off and domestic sewages. A total of five sampling stations were established for measurement of water pollution and the measurement of cytogenetic alterations in vivo is considered an initi...

Sub-lethal toxicity of zinc chloride (11.5 ppm) on the respiratory organs of the Channa striata has been analysed. The mucous cells show periodic fluctuations in their number, size and staining properties elaborating larger quantities of sulphated mucopolysaccharides. The respiratory epithelium (RE) of the respiratory (secondary) lamellae (SL) of the gills shows periodic lifting with deformity ...

In the present study different regions in the scales of Channa punctatus were investigated for elemental composition to see the impact of mercury on them. Five sublethal concentrations of mercury were used after calculating the LC50 value which is 1.21mg/L in 96 hours. When focal and lepidontal regions of scales were seen under electron probe analysis (JEOL 8600M), they were composed of four ma...

This study aims to determine the effect of giving EM4 probiotics on growth and survival rate snakehead (Channa striata). research was carried out at Fish Hatchery Laboratory, Faculty Marine Fisheries, Universitas Syiah Kuala. conducted using a Complete Randomized Design (CRD) method with 4 treatments used, namely A (control), B (EM4 6 ml/kg feed), C 8 D 10 feed). The results showed that additio...
