The grass carp (Ctenopharyngodon idella) is one of the most important freshwater fish species in China and the world; grass carp production accounts for about 16% of the world’s total freshwater aquaculture [1]. In 2015, Wang et al. performed whole-genome sequencing and de novo assembly for a female (0.9 Gb) and male grass carp (1.07 Gb) by using the shotgun sequencing strategy [2]. Based on th...

Transforming growth factor1 (TGF1) is a potent regulatory cytokine with pleiotropic effects on the immune system. To examine the role of TGF1 in fish immunity, the full-length cDNA of grass carp TGF1 was isolated from grass carp spleen. The open reading frame of grass carp TGF1, 1134 bp in length, encodes a 377 amino acid protein. Tissue distribution study by RT-PCR showed TGF1 mRNA was predomi...

Grass carp (Ctenopharyngodon idellus) is one of the most important freshwater fish that is native to China, and crisp grass carp is a kind of high value-added fishes which have higher muscle firmness. To investigate biological functions and possible signal transduction pathways that address muscle firmness increase of crisp grass carp, microarray analysis of 14,900 transcripts was performed. Co...

The exotic grass carp ( Ctenopharyngodon idella ) has been used for almost a half a century in the United States as a biological agent to control and manage aquatic plants. This long-lived generalist herbivore consumes large amounts of vegetation and can considerably alter habitat and impact aquatic communities. We conducted a literature review to determine whether previous studies adequately a...

The grass carp (Ctenopharyngodon idellus) is an important species in freshwater aquaculture both in China and on a global scale. Variety degeneration and frequent diseases have limited the further development of grass carp aquaculture. Thus, new and improved varieties are required. Here, we identified and assessed the body weight and disease resistance in a random mating population of 19 ♀ × ...

Macrophage colony-stimulating factor (CSF-1/M-CSF) is a key factor for the differentiation, growth and survival of monocytes/macrophages and osteoclasts. The functions of M-CSF have been well characterized in mammals. In this study, we have cloned and sequenced the cDNA of M-CSF2 in grass carp. The grass carp M-CSF2 cDNA was 1487 bp in length, containing an open reading frame of 855 bp that enc...

A widespread grass carp hemorrhagic disease (GCHD) caused by grass carp reovirus (GCRV) has been known in China since 1983. A virulent reovirus strain, HZ08, was isolated from diseased grass carp in Zhejiang Province, China. We sequenced and analyzed the complete genome of strain HZ08 and compared it with published GCRV genome sequences, contributing to the evidence of several genotypes of GCRV...

Introduction Grass carp (Ctenopharyngodon idellus) is an important species of freshwater fish in China. It accounts for about 20% of the total freshwater fishery production. Hemorrhagic disease of grass carp is the most serious infectious disease of grass carp and causes significant losses of fingerlings during rearing. Survival to market size is less than 20% if this disease occurs. Hemorrhagi...

Grass carp reovirus (GCRV) is a causative agent of haemorrhagic disease in grass carp that drastically affects grass carp aquaculture. Here we report a novel GCRV isolate isolated from sick grass carp that induces obvious cytopathic effect in CIK cells and name it as GCRV096. A large number of GCRV 096 viral particles were found in the infected CIK cells by electron microscope. The shape, size ...

Hornwort (Ceratophyllum demersum L.) and other aquatic macrophytes have historically been mechanically removed from the Rangiriri drain and Churchill East drain to maintain drain efficiency. As an alternative control method for the high plant biomass that accumulates at the end of summer, the effect of stocking diploid grass carp (Ctenopharyngodon idella L.) on the aquatic vegetation was evalua...
