Sixty days feeding experiment was conducted on grass carp fry fed isocaloric diets with variable protein levels in order to evaluate its growth response. Different diet ingredients were analyzed for % age protein, % age fat, % age ash, % fiber, % age moisture contents and energy. Five isoenergetic (17.91 ± 0.02 Kg MJ ) and isolipidic (8.56 ± 0.09 g) diets with varying protein levels PL1 (20%), ...

Carbon stable isotope signatures can effectively trace food sources, elucidate trophic interactions, and presumably reflect food web structure. The present study conducted a dietswitch experiment using freshwater teleost grass carp Ctenopharyngodon idella cultured for 3 mo with artificial feed that had a distinct carbon stable isotope composition. Turnover and fractionation of carbon stable iso...

Pesticides are usually used as an effective tool to control pests in agriculture; however, these chemicals may be a threat nontarget organisms, especially aquatic because environments the last station of pollutants. The present study evaluated toxicity commercial formulation neonicotinoid (acetamiprid 20% SP) systematic pesticide on survival, hematology, and histology grass carp (Ctenopharyngod...

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...

The present study was designed to investigate the effect of Spirulina platensis (SP) supplemented diets on growth performance, digestive enzymes, hepatic antioxidants and innate immunity biomarkers in juvenile grass carp (Ctenopharyngodon idella). Two hundred forty juveniles (average weight 4.81 ± 0.13 g) were divided into four treatment groups triplicates (20 fish/replicate) fed with containin...
