“…It has almost replaced crucian carp for its higher growth rate in recent years and annual production was around 3 million tonnes (Fishery Bureau of the Ministry of Agriculture of the People's Republic of China 2010). A number of studies have been reported on feeding regime, feeding stimulants, compensatory growth and macronutrient requirement (Xie et al 2001;Yang et al 2006;Tan et al 2009;Pei et al 2004;Pan et al 2009). However, many of the quantitative requirements of microelement for gibel carp have not been determined.…”

A 10‐week feeding trial was conducted in a flow‐through system to determine dietary choline requirement for juvenile gibel carp (Carassius auratus gibelio) (5.5 ± 0.1 g). Purified basal diet was formulated using vitamin‐free casein as protein source. Choline chloride was supplemented to the basal diet to formulate seven diets containing 76.1, 163, 356, 969, 1457, 2024 and 4400 mg kg−1 choline. Dietary methionine was 0.58%, less than the requirement (0.69%). The results indicated that specific growth rate (SGR) was higher in the fish fed 2024 mg kg−1 diet than the control group. Feeding rate and feed efficiency were not significantly affected. Protein productive value increased as dietary choline increased from 76.1 to 2024 mg kg−1 diet and was lower in the fish fed the diet containing 4400 mg choline kg−1 diet. Serum high‐density lipoprotein cholesterol (HDL‐C) and total cholesterol significantly increased with increasing dietary choline up to 1457 mg kg−1, and no differences were found with further increase. Fish carcass fat contents decreased significantly with increased dietary choline. Hepatic lipid contents increased with dietary choline up to 1457 mg kg−1 and then decreased. Quadric regression of SGR and plasma HDL‐C indicted dietary choline requirement was 2500 and 2667 mg kg−1 diet, respectively.

An 11-week growth trial was conducted to determine dietary myo-inositol (MI) requirement for juvenile gibel carp (Carassius auratus gibelio). Myo-inositol was supplemented to the basal diet to formulate six purified diets containing 1, 56, 107, 146, 194 and 247 mg MI kg À1 diet, respectively.Each diet was fed to triplicate groups of juvenile gibel carp (initial body weight 3.38 AE 0.27 g, mean AE SD) in a flowthrough system. The diets were randomly assigned to different fish tanks.

“…Although it is expressed in several organs, highest expression levels are in general observed in the liver, because this organ functions as the main storage of iron in most organisms. In fish, maintenance of optimal hepatic iron and blood haematocrit concentration seem to depend on a certain threshold in dietary iron concentration (Pan et al 2009). Due to the iron-chelating effects of phytic acid, reduced transcription rates may be primarily caused by an iron deficiency and, therefore, imply potential malnutrition.…”

Despite considerable progress in the production of alternative diets, small concentrations of antinutrients remain common in aquaculture nutrition, resulting in a perpetual limitation with regard to the inclusion of plant ingredients in aquafeeds. These compounds are known to impair the general performance of fish when fed for a prolonged period of time, potentially affecting the animal's susceptibility to stress, too. Therefore, a 12-week feeding trial was conducted to examine the chronic effects of purified rapeseed protein concentrate (RPC), containing low concentrations of glucosinolates and phytic acid, on the relative expression of multiple target genes in the liver of juvenile turbot (Psetta maxima, L.). Our results revealed divergent patterns of gene expression, suggesting different coping strategies dependent on the grade of RPC substitution. Data implies increased metabolic rate of turbot fed a 33% RPC-substituted diet due to an upregulation of cytochrome c oxidase mRNA, accompanied by minor adjustments in metabolic pathways. While no signs of reduced welfare were found, data adumbrate a beneficial hormetic reaction. In the highest treatment level (66% RPC), diminished fish condition and reduced growth performance coincided with a downregulation of insulin-like growth factor I, further indicating a potential impaired resistance to stress. An additional downregulation of transferrin hints towards an increased liability to bacterial infections.
