The current research was conducted with the aim to investigate rate of chromium accumulation in various tissues commercially valuable freshwater fish, Grass Carp, Ctenopharyngodon idella. Investigation included skin, muscles, liver, swim bladder, intestine, and gills fish. For this purpose, fish were exposed sub lethal concentration hexavalent form potassium dichromate a dose 120 mg/L for 40, 2...

32 thousands of juveniles grass carp Ctenopharyngodon idella were reared in Fadak fish farm about 15 g. They transferred from culture station Marine Science Center and spread equally four ponds each 8.5 donum. The density was 940 /donum the period 15/ May to December 2007. Total weight for nearest milligram taken monthly. Fishes fed daily with green alfalfa as a main food item rate 8-15% body a...

Relative contributions of aquaculture-origin and naturally-reproduced grass carp (Ctenopharyngodon idella) in the Laurentian Great Lakes have been unknown. We assessed occurrence distribution wild using ploidy otolith stable oxygen isotope (?18O) data. inferred natal river dispersal from location for microchemistry estimated ages fish to infer years which natural reproduction introductions occu...

In the present study, we investigated effects of compound kaempferol 3-a-L-(4-O-acetyl)rhamnopyranoside-7-a-L-rhamnopyranoside (SA) isolated from Dryopteris crassirhizoma during immune-related gene expression in Ctenopharyngodon idella head kidney macrophages (CIHKM). The expression of immune-related genes (IL-1β, TNF-α, MyD88, and Mx1) were investigated using real-time PCR at 2 h, 8 h, 12 h, a...

Problem statement: The utilization of crystalline amino acids was detected for growth performance and body composition of juvenile grass carp (Ctenopharyngodon idella). Approach: LLysine sulphate and Methionine Hydroxy Analog-Ca (MHA-Ca) were selected for determination. Two diets were formulated with or without amino acids supplementation. Each diet was assigned to 10 tanks in a completely rand...

Benthic fluxes of carbon dioxide (CO2) and methane (CH4) were evaluated in grass carp Ctenopharyngodon idella (G), silver carp Hypophthalmichthys molitrix (S), and bighead carp Aristichthys nobilis (B) polyculture systems, to which topmouth culter Erythroculter ilishaeformis (T), Pacific white shrimp Litopenaeus vannamei (P), or common carp Cyprinus carpio (C) were added. These systems, GSBT, G...

The aim of the study was to investigate the physical difference in biochemical characteristics of spermatological and seminal plasma and also ultrastructure of spermatozoa in six carp species, viz. catla, Catla catla, rohu, Labeo rohita, kalbasu, Labeo calbasu, mrigal, Cirrhinus mrigala, silver carp, Hypophthalmichthys molitrix and grass carp, Ctenopharyngodon idella. Semen yield from different...
