Retinoic acid-inducible gene I (RIG-I) and melanoma differentiation-associated gene 5 (MDA5) are critical cytosolic sensors that trigger the production of interferons (IFNs). Though their recognition functions are well identified, their unique roles in the downstream signal transduction remain to be elucidated. Herein, we report the differential effect between grass carp (Ctenopharyngodon idell...

Two stocks of grass carp Ctenopharyngodon idella Val were collected from North, Mazandran and South, Khuzestan to compare some morphometric and meristic characters. The Khuzestan stocks were significantly greater in body length, intestine length and number of vertebrae than the Mazandran stocks (p<0.05). The body width, depth of Mazandran were higher but gill raker lower than another stock. The...

The larvae of grass carp Ctenophargodon idella were fed on three types live food Brachionus calyciflorus, Artemia sp. and Daphnia magna. study showed that is very important to achieve high growth survival fish larvae. average weights C. B. calyciflorus 118.12+3.0 mg / 29.48+0.8 mm respectively, in case rates 103.13+1.5 mg/ 25.34+1.4 larvae, while the mixed rate 122.80 + 1.8 30.08 1.1mm /larvae ...

Ten years ago, very little was known about the genetics of most of the cyprinid species of interest to aquaculture in Asia, for example the Chinese carps, silver carp (Hypophthalmichthys molitrix), bighead carp (Aristichthys nobilis) and grass carp (Ctenopharyngodon idella); Indian major carps, catla (Catla catla), rohu (Labeo rohita) and mrigal (Cirrhinus cirrhosus); and the silver barb (Barbo...

MicroRNAs (miRNAs) are endogenous small non-coding RNAs that play crucial roles in numerous biological processes. However, the role of miRNAs in antibacterial defence in fish has not been fully determined. Here, we identified that nine miRNAs are differentially expressed in kidney between susceptible and resistant grass carp strains. Analysis of spatial and temporal miRNA expression patterns su...
