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...

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...

Extracts and preparations made from the animal origin were used extensively in folk and modern medicine for treating many human diseases. In the present study efforts have been made to find the antimicrobial effect of the mucus of two bottom dwelling fresh water fishes namely, Channa punctatus and Cirrhinus mrigala. Fish mucus were tested against ten pathogenic bacteria such as Escherichia coli...

The aim of the present study was to evaluate the acute effects of commercial formulation of traiazophos, profenofos, carbofuran and carbaryl in Cirrhinus mrigala fingerlings. Pesticides were applied to fingerlings that had been grown under optimised standard conditions under a maintained static bioassay system. Probit analysis was used for the estimation of LC50 values, which were ascertained a...

Erythrocyte abnormality test has been used to detect the genotoxic effect of dyeing industry effluent on the fish. The 96h LC50 of effluent against Cirrhinus mrigala was calculated by Finney method and three sublethal concentrations 24.48%, 12.24% and 6.12% were made. Fishes were kept in concentrations and blood was smeared after 24h, 48h, 72h and 96h. Eleven types of erythrocyte abnormalities ...

Harike wetland was declared a Ramsar site in 1990. It is located at the confluence of two major rivers of Indus rivers system, the Beas and the Sutlej, but was never explored extensively for its existing fish biodiversity. Earlier only 27 fish species of commercial value were reported from the wetland. Acknowledging its importance for rich diversity fish assemblages in seven different reaches o...

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...

Androgens are necessary for normal male phenotype expression, including the initiation and maintenance of spermatogenesis. Many physiological actions of androgens are mediated by the androgen receptor (AR), a member of the nuclear receptor super family. In the present study focused to identify the expression of AR in the gonads and brain of Cirrhinus mrigala. The gene specific primers were used...

An eight week feeding trial was conducted to evaluate the potential of Gliricidia maculata leaf meal as dietary protein source in the diet of Cirrhinus mrigala fingerlings. Four experimental diets were formulated to contain 20%, 30%, 40% and 50% G. maculata leaf meal (Diets 1 – 4) to partially replace other protein ingredients in the C. mrigala diet. The diet containing 0% leaf meal served as t...

A growth study was conducted to determine the dietary threonine requirement of juveniles of the Indian major carp (Cirrhinus mrigala) known as “mrigal”. Diets containing casein and gelatin as sources of intact proteins were supplemented with crystalline amino acids to obtain a crude protein content of 40%. Six diets with different levels of threonine (1.0, 1.3, 1.5, 1.7, 1.9 and 2.1%) were fed ...
