6-Phosphogluconate dehydrogenase (6-PGD, E.C.: 1.1.1.44) was purified and characterized from the hepatopancreas of grass carp (Ctenopharyngodon idella) for the first time. Grass carp represents the second largest aquaculture industry in the world after silver carp, constituting 14.7% of the world aquaculture production, with an average annual increase of 14% in China, mainly as a source of food...

Peptidoglycan recognition proteins (PGRPs) are pattern recognition molecules of innate immunity. In this study, a long-form PGRP, designated as gcPGRP6, was identified from grass carp Ctenopharyngodon idella. The deduced amino acid sequence of gcPGRP6 is composed of 464 residues with a conserved PGRP domain at the C-terminus. The gcPGRP6 gene consists of four exons and three introns, spacing ap...

Global fish production from aquaculture has rapidly grown over the past decades, and grass carp shares the largest portion. However, hemorrhagic disease caused by grass carp reovirus (GCRV) results in tremendous loss of grass carp (Ctenopharyngodon idella) industry. During the past years, development of molecular biology and cellular biology technologies has promoted significant advances in the...

In present study the effect of feeding frequency on growth performance, feed efficiency and survival rate of juvenile of grass carp were investigated. Three groups of juvenile grass carp (average weight 4.31±0.1 g) designed with three feeding frequencies one meal a day (D1), two meals a day (D2) and four meals a day (D3) with two replicates of each treatment combination were applied in this exp...

Willomitzer J.: Therapy of Major Ectoparasitoses in Grasscarp (Ctenopharyngodon idella ) Fry and Fingerlings. Acta vet., 49, 1980: 279-282. Dipping, short-term and long-term baths in solutions of common substances (potassium permanganate, formaline, common salt) currently recommended for the control of ectoparasites of the genera Chilodonella, Trichodinella and Dactylogyrus in grasscarp fry and...

A study was carried out on the optimal dose of inorganic fertilizer used in carp polyculture system over a period of 10 months. Three treatments were assigned: without inorganic fertilizer, with the application of 100 kg/ha/month inorganic fertilizer and 150 kg/ha/month inorganic fertilizer as T1, T2 and T3, respectively. Each treatment had three replications. The selected indigenous carp speci...

With recent findings of grass carp Ctenopharyngodon idella in tributaries of the Great Lakes, information on developmental rate and larval behavior is critical to efforts to assess the potential for establishment within the tributaries of that region. In laboratory experiments, grass carp were spawned and eggs and larvae reared at two temperature treatments, one "cold" and one "warm", and track...

A freshwater plant, water hyacinth (Eichhornia crassipes) is commonly found in public waters Indonesia. Water often experiences blooming which causes negative impacts such as lowering oxygen levels, reducing the number of fish, increasing evapotranspiration, disrupting transportation, becoming habitat for disease vectors, and others. However, can be used an alternative raw material because it s...

The construction of spur dikes alters the flow pattern rivers and affects upstream migration behavior fishes. Traditional rock-fill experimental permeable with a “Weighted Excess Storage” (WES) profile were evaluated using hydrodynamic experiments on juvenile Grass Carp (Mylopharyngodon idella). swimming ability paths in dike analyzed, relationship between success rate diversity velocity was st...
