The effect of cypermethrin pesticide on juvenile rohu (Labeo rohita) was determined in captive condition. Live and healthy (average initial weight 21g) were exposed to five concentrations Cypermethrin 0.63, 0.13, 0.025, 0.005, 0.001 ppm one control group (no pesticide) with two replications for each treatment. mean temperature pH the experimental tanks 27.53±0.41ºC 7.22±0.013 ppt, respectively....

dimethoate (organophosphate insecticide) and lambda-cyhalothrin (synthetic pyrithroid) aretwo frequently used pesticides due to their high effectiveness and rapid breakdown into environmentally safeproducts. the aim of this present study was to assess and compare the acute toxicity of dimethoate(rogor30%ec) and lambda-cyhalothrin (5%ec) on labeo rohita (hamilton). acute toxicity bioassay wascar...

The effects of dietary Pseudomonas aeruginosa VSG-2 supplementation on innate immunity and protection against Aeromonas hydrophila infection were evaluated in Labeo rohita. Fish were fed for 60 days with control diet or 3 experimental diets containing P. aeruginosa VSG-2 at 10(5), 10(7), and 10(9) cfu g(-l), respectively. Various innate immune parameters were examined at 30 and 60 days post-fee...

A total of 1671 ESTs of Labeo rohita were retrieved from dbEST database and analysed for functional annotation using various computational approaches. The result indicated 1387 non-redundant (184 contigs and 1203 singletons) putative transcripts with an average length of 542 bp. These 1387 transcript sequences were matched with Refseq_RNA, UniGene and Swiss-Prot on high threshold cut-off for fu...

In the present study, a new species Myxobolus dermiscalis n. sp. infecting scales of Labeo rohita, an Indian major carp from Harike Wetland in Punjab, India has been described on the basis of spore morphology and amplification of a part of 18S rDNA gene. The pseudocysts of M. dermiscalis n. sp. are milky white with irregular outline, 0.5-3.6 mm in diameter embedded within the dermal scale in th...

The present research was designed to study and compare the biochemical parameters in Labeo rohita due to exceptional nutritional value of this fish as a protein source in developing countries. The protein and heavy metal (Zn, Cu, Ni) activities were determined spectrophotometrically. The proximate analysis of L. rohita collected from different localities of Pakistan revealed that the protein (1...

use of different pesticides in the agriculture sector, in order to boost crop yield within a short time period and low labor, has been tremendously increased since the last decade. pesticide use has elevated crop yield but has produced a number of pronounced problems regarding environmental and health safety. the continuously deteriorating toxicological effects of these pesticides are not only ...

Aquaculture production relies on the quality of feed and a balanced diet helps to maximize fish yield profitability. Plant based supplements in aquaculture are ideal as growth promoters immunostimulants. The present study assessed effect medicinal plant, Acalypha indica leaf feeding energetics freshwater fish, Labeo rohita. Incorporation different concentrations supplemented enhanced assimilati...

A sixty-day study was carried out to compare the growth of hybrid between Labeo rohita (rohu) and bata (bata) with one parental species, rohu. The fertilization hatching rates found be lower in than those After three days spawns were reared earthen nursery ponds for sixty days. weight first ten and, length following fifty obtained compared rohu significant difference observed. showed faster rat...

The present study investigated the use of fermented Prosopis juliflora pods (PJP) as a carbohydrate source, alternative to rice bran (RB), and a PJP based diet formulation supplemented with probiotics Lactobacillus acidophilus (LA), Lactobacillus bulgaricus 009 (LB) and Streptococcus thermophilus (ST) on the growth of Labeo rohita (rohu) fingerlings. The diets were isonitrogenous (39%) and isoe...
