Farmed and wild samples of two weight Cirrhinus viz., 501-900 g and 901-1300 g of Cirrhinus mrigala were collected from a Commercial Fish Farm and from river Chenab at Trimu Head Jhang, respectively. The extracted residues were pesticides analyzed through reverse phase high performance liquid chromatography (HPLC) technique. Endosulfan α, p, p’-DDT, methamidophos, carbofuran, diazinon, parathio...

The present communication describes three new species of myxosporeans (Myxozoa: Myxosporea: Bivalvulida), Myxobilatus odontamblyopusi sp. n., Myxobolus catmrigalae sp. n. and M. buccoroofus sp. n. from Odontamblyopus rubicundus (HamiltonBuchanan), Catla-Mrigal hybrid carp [male parent fish Catla catla (Hamilton-Buchanan) × female parent fish Cirrhinus mrigala (Hamilton-Buchanan)] and Labeo bata...

Investigations on the incidence of myxozoan parasites (Myxozoa: Bivalvulida) in fishes have assumed immense importance in view of severe pathogenicity and mortality caused by these organisms on their hosts. The present communication records three new species of myxosporeans, Myxobolus calcariferum sp. n.; Myxobolus chinsurahensis sp. n. and Myxobolus mrigalhitae sp. n. from different food fishe...

The freshwater fingerlings of Cirrhinus mrigala were exposed to Nickel in acidic medium pH = 6.0 (5.8-6.2), alkaline medium pH = 9.0 (8.8-9.2) and water hardness (40 mg/l) of CaCO3. The study indicates that nickel accumulation was significantly influenced by pH and hardness of water The concentration was found to be significantly higher at pH = 9.0 than at pH = 6.0. Also the presence of hardnes...

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...

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) ...

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...

myxozoans are an economically important group of microscopic parasites best known for the diseases they cause in commercially important fish hosts. the classification of myxosporeans is generally based on the morphology of their myxospores. without molecular data, it is very difficult to identify new or existing species. dna sequence information is therefore, a prerequisite to taxonomic and phy...

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...

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...
