the toxic impact of copper sulfate in lethal and sublethal concentrations was investigated on gill of grass carp, ctenopharynogodon idella . in this investigation, 27 specimens were used as control group and three treatment groups were treated with 2.5 and 5mg/l of copper sulfate. gill samples were collected from each treatment after 96hr and lesions were analyzed by light microscopy. in histop...
The main objective of this study was to evaluate alternate vegetable proteins as a replacement for fish meal in diets of Labeo rohita and Ctenopharyngodon idella and use the findings to formulate a cost effective diet for freshwater fish species. Fish of an average weight of (L. rohita 1.91±0.05; C. idella 19.57±0.09 g) was stocked in four earthen fish ponds. The feed was prepared from five dif...
The relationship of gonad weight and liver weight with body weight of six fish species viz; Catla catla, Labeo rohita, Cirrhina mrigala, Hypophthlamichthys molitrix, Ctenopharyngodon idella and Cyprinus carpio under the influence of artificial feed, broiler manure, buffalo manure, N:P:K (25:25:0) and a control pond were examined after a rearing period of one year. The positive relationship betw...
Macrobrachium snpurii sp. nov., collected from the Karamana River, in the lower reaches of Western Ghats, is described and illustrated. DNA barcoding using Cytochrome B gene sequences has elucidated the taxonomic status of the new species and the NJ tree reveals that M. snpurii sp. nov., is phylogenetically close to M. idella idella. However, morphometric and meristic features of the species sh...
The susceptibility of Macrobrachium idella, M. lamerrae and M. rosenbergii to white spot Ž . syndrome virus WSSV was tested by immersion challenge, oral route and intramuscular injection. Their susceptibility to WSSV was compared with that of Penaeus indicus and P. monodon. The WSSV caused 43.3% and 53.3% mortality in M. lamerrae and M. idella, respectively, by immersion method and 53.3% and 66...
BACKGROUND De novo transcriptome sequencing is a robust method of predicting miRNA target genes, especially for organisms without reference genomes. Differentially expressed miRNAs had been identified previously in kidney samples collected from susceptible and resistant grass carp (Ctenopharyngodon idella) affected by Aeromonas hydrophila. Target identification for these differentially expresse...
The grass carp (Ctenopharyngodon idella) is an important commercial farmed herbivorous fish species in China, but is susceptible to Aeromonas hydrophila infections. In the present study, we performed de novo RNA-Seq sequencing of spleen tissue from specimens of a disease-resistant family, which were given intra-peritoneal injections containing PBS with or without a dose of A. hydrophila. The fi...
این تحقیق در یک دوره 21 روزه از شهریور تا آبان سال 1388 در اداره توسعه ماهیان گرمابی شهید ملکی اهواز انجام گرفت. هدف این تحقیق بررسی تاثیر شوری های مختلف (کمتر از 1، 3، 6، 9 و 12 قسمت در هزار) بر مقادیر هورمون کورتیزول و گلوکز ماهی کپور علفخوار انگشت قد (ctenopharyngodon idella) بود. ماهیان کپور علفخوار (با طول کل 069/0±10 سانتی متر و وزن 239/0 ± 55/12گرم) در مخازن 250 لیتری به تعداد 15 ماهی در...
