... freshwater fishes. Aspergillosis is a fungal disease of fish. This study was designed to examine a fungal infection in silver carp, Hypophthalmichthys molitrix. The infected fish showed clinical signs such as: eroded gills, damaged fins and lesions all over the body. The fish specimens showed mild to severe infection. The infection caused by fungus was confirmed by isolating the pathogenic fungus from affected...

Overall, seventeen fish species were recorded in the study areas indicating a decrease in the number of species in Ravi. The results have shown that the water of Ravi is unsafe for aquatic life and irrigation. Metal concentration in the fish meat is higher than the recommended dietary allowance (RDA) parameters indicating a serious health threat to both, the fish and human...

...t of oxidative stress on gill and gut enzyme activity in Paramisgurnus dabryanus was studied under different breathing restraint treatments. A total of 150 healthy mature individuals (mean initial body weight = 16.1 ± 3.7 g and mean initial total fork length = 13.1 ± 1.2 cm) were selected for the experiment. The experimental specimens were separated into three modes: control group (n = 50) without any stress treatments; inhibited group (n ...

Nematodes were collected from soil around the rhizospheres of sponge gourd (Luffa cylindrical L.) field in the vicinity of National Nematological Research Centre, University of Karachi and further processed by Cobb’s sieving and Baermann’s funnel techniques. Specimens were killed, fixed and identified up to species level under l...

Generally, total carbohydrates are determined by the difference of the entire proximate body composition indices, and in this study, it was found that the liver contains maximum carbohydrates (percentage) relative to other sections of the body examined. Weight group W3 was found to have higher nutrients significantly (p<0.05) as compared to W1 and W2. Further, it is found that a...

...thological variations in gills, liver, kidney and skin of different fishes were noticed when exposed to heavy metals, thus indicating severity of heavy metal toxicity. The current study was focused on the toxicological effect of Cr, Hg, Ni and Cd in different type of fishes and it would be useful for the scientific community to restore different metals contaminating water.

Methanolic extract of P. eryngii showed increasing % mortality against red flour beetle (Tribolium castaneum) in methanolic extract with increasing concentration after 24 and 48 h exposure time. Maximum mortality (100%) was noticed at 300 mg/L after 40 h exposure time. Hence, methanolic extract of P. eryngii can be used as a natural pesticide, especially in stored grains. ...
