effect of zinc cyanide on protein and certain metabolites content and some enzymes activitieswas evaluated in liver, muscle and gill tissues of the freshwater fish, cirrhinus mrigala, during exposure andfollowing cessation of exposure. fish exhibited significant alterations in the biochemical parameters in alltissues studied. levels of total protein decreased in all tissues, where as free amino...

freshwater fish cirrhinus mrigala were exposed to lethal concentration (5 mg/l) for 1,2,3,4 days and sublethal concentration (1 mg/l) for 1,7,14,21 days of cypermethrin to examine the enzymes activity, in functionally three different tissues namely, gill, liver and muscle. activities of aspartate aminotransferase (aat), alanine aminotransferase (alat) and glutamate dehydrogenase (gdh) increased...

Catalase is one of the most active antioxidant defence enzymes known for being highly cooperative with SOD and other H2O2 producers at high flux of hydrogen peroxide. In the present study, catalase activity was analyzed in liver samples of different animals both by ge l ac t iv i t y s ta in ing method as we l l as spectrophotometric biochemical method. Five different animals like fish (Cirrhin...

The study was conducted to evaluate the prevalence of food borne trematode infections in commercially important fish species of Pakistan such as, Labeo rohita (rohu), Cirrhinus mrigala (mori), Catla catla (thaila), Hypophthalmichthys molitrix (silver carp). For this purpose 222 different samples of fishes were collected from different water bodies i.e. Rawal Dam, Islamabad, Mangla Dam (Mirpur) ...

 Euglenophyte bloom is a common problem in most of the aquaculture ponds in Bangladesh. In the present study we conducted an experiment to control euglenophyte bloom for achieving better fish production using duckweed (Lemna minor) and lime. The experiment was carried out using four treatments, i.e., ponds were supplied with duckweed (T1), lime treatment (T2), both duckweed and lime (...

Sensory and certain microbial analyses were applied to assess the quality of raw fish sold at a market in Siliguri cityof West Bengal, India. In regular surveys undertaken during June to August 2008, a particular fish species was randomly selected, its source was noted and a sensory analysis, the quality index method (QIM) was applied to assess its quality Raw fish samples were also collected a...

this 4x2 factorial study compared the effect of four sites (a=siphon as upstream, andb=shahdera, c=sunder and d= balloki as 3 downstream sites) during low and high flow seasons of river ravion metal cconcentrations in muscles from cirrhinus (c) mrigala, a bottom feeder carp. while weight andlength of studied specimens did not differ significantly (p>0.05). overall metal accumulations appeared i...
