The effect of phenol on haematological components of Indian major carps, Catla catla, Labeo rohita and Cirrhinus mrigala were observed. After exposure to sublethal concentrations of 5.17 mg l(-1), 6.06 mg l(-1) and 6.99 mg l(-1), the number of red blood cells, haemoglobin content and packed cell volume all decreased but the glucose level increased. The order of decrease in the haematological co...

The response of NADPH cytochrome C reductase (NCCR) activity in liver of Labeo rohita fish exposed to the pesticides, 0.25 microgl(-1) endosulfan and 2 mg/l monocrotophos was studied. In terms of specific enzyme activity (mU/mg protein) a significant level of NCCR was observed in the liver tissues of Labeo rohita exposed to the pesticides, when compared to the control fish (2.460 mU/mg protein)...

Three species of Indian major carp (Labeo rohita,Catla catla,Cirrhinus mrigala) were collected from local fish market and fishing sites of river Brahmaputra for determining the nutritional value,seasonal variation of proximate composition and vitamin A content of these fishes.Results obtained show that there is no much significant seasonal variations in body composition of Indian major carp tho...

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) ...

A study was conducted on the economically important fishes Labeo rohita (Hamilton 1822), Tortor (Hamilton 1822) and Labeo calbasu (Hamilton 1822) stocks from the Ken, the Paisuni and the Tons rivers in the Vindhyan region. Asymptotic length was maximum in L. rohita (946, 833 and 962 mm) as compared with T. tor (822, 787 and 946 mm) and minimum in L. calbasu (567, 612 and 692 mm) in the Ken, the...

The present study was conducted to determine heavy metal (cadmium and chromium) concentrations in gills, kidneys, liver, skin, muscles and scales of three fish species (Catla catla, Labeo rohita and Cirrhina mrigala) from three stations viz. Lahore Siphon (Up stream), Shahdera Bridge and Baloki Headworks (Down stream) in the river Ravi, Pakistan. Heavy metal concentrations varied significantly ...

Two 90 days experimental trials were conducted to evaluate the effect of artificial diet (35% protein) on sensory quality of yearlings of Indian major carps (Labeo rohita, Cirrhinus mrigala and Catla catla). Experimental diet was given at 3% of fish wet body weight per day. After 90 days trial organoleptic study of fried fish was carried out by twelve panelists using hedonic scale for each spec...

We examined and compared heavy metals bioaccumulation in Cyprinus carpio and Labeo rohita netted from Sardaryab, a tributary of River Kabul. By using atomic absorption spectrometry we assessed different organs including livers, gills, and muscles. Metals studied were chromium, iron, zinc, lead, and copper. Livers of both species showed higher concentrations of metals while muscles showed the le...

Different male germ cells identified on the basis of histological and cytological characteristics in the testicular lobules of Labeo rohita have been grouped into spermatogonia, primary spermatocytes, secondary spermatocytes, spermatids and spermatozoa. The seasonal changes of the testis in L. rohita have been described according to its morphological peculiarities as well as to its variations i...

The present study was conducted to reveal a histological analysis on the gills of Labeo rohita and Hypophthalmichthys molitrix specimens were observed to reveal the histo-pathological characteristics of the gills of these freshwater carps. The histological examination of the gills of Labeo rohita revealed the proliferation of bronchial tips, shortening and fusion of secondary gill lamellae, des...
