“…It seems that decreased digestibility of some macronutrients in response to the dietary oil oxidation could impair the growth, feed utilization and survival in many fish species (Chen et al, ). The conflicting results obtained regarding the effects of green tea and rancid diet may originate from differences in digestion and absorption mechanism of different fish species, dose or sources of green tea or oxidized oil in the diet, and also duration of the experiment (Chen et al, ; Eder & Stangle, ; Fontagne et al, ; Mourente, Diaz‐Salvago, Bell, & Tocher, ; Tocher et al, ).…”

The present study was conducted to determine the effects of dietary oxidized fish oil (OFO) and green tea extract (GTE) on growth performance, antioxidant status and immunological parameters in Siberian sturgeon (Acipenser baeri). Fish weighing about 108 g were randomly assigned to one of nine dietary treatments (control diet without OFO and GTE; diets containing only 25 or 50 mg/kg of GTE; diets containing 50 mg/kg of OFO combined with 0, 25 or 50 mg/kg of GTE; diets containing 100 mg/kg of OFO combined with 0, 25 or 50 mg/kg of GTE) with three replicates of 15 fish stocked in fiberglass tanks using a completely randomized design. Growth performance indices, immunological parameters and antioxidant status of all treatment groups were determined using appropriate assays and compared. Results showed that GTE could enhance growth performance. Feeding GTE alone or combined with the OFO could decrease the hepatosomatic index (HSI) and viscerosomatic index (VSI). Serum lysozyme activity and antibody level were increased significantly by GTE alone or combined with OFO compared to the oxidized diets (p < 0.05). Conversely, lipid peroxidation products and antioxidant enzyme activity were significantly lower in GTE treatment groups and those that received combination of GTE and OFO compared to the oxidized diets. Low‐density lipoprotein (LDL) level in GTE groups was lower than other treatment groups (p < 0.05) however, in OFO treatment groups the LDL level in fish serum was significantly increased in comparison with the other treatment groups (p < 0.05). GTE and OFO alone or combined together significantly decreased the levels of triglyceride and cholesterol compared to the control group (p < 0.05). In conclusion, immunological and biochemical parameters were improved by inclusion of GTE into Siberian sturgeon rancid diets which can protect fish from the oxidative damage challenged by dietary oil oxidation.

“…In the present study, fish fed OFO, especially in high dose, had high fillet fat content, and high HSI and VSI values. Green tea can enhance fat metabolism and prevent the cholesterol accumulation in fish body (Chen et al, ). This mechanism can result in lower HSI and VSI indices and fillet fat content in groups that received GTE.…”

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.

“…Lipids can provide crustacean species with energy, essential fatty acids, phospholipids, sterols and serve as a carrier for fat‐soluble vitamins (Holme, Southgate & Zeng, ). Traditionally, fish oil has been widely used as the main lipid source in aquafeed because of its high content of essential fatty acids, especially n‐3 highly unsaturated fatty acids (HUFA) such as eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA) (Chen et al., ). In the past decades, aquaculture production has increased to 52.5 million tonnes with an economic value of US $98.5 billion (Bostock et al., ).…”

Effect of dietary lipid source and vitamin E on growth, non-specific immune response and resistance to Aeromonas hydrophila challenge of Chinese mitten crab Eriocheir sinensis

et al. 2018

Six purified diets were formulated to contain three lipid sources, fish oil (FO), linseed oil (LO) and soybean oil (SO), at 6% diet lipid crossing two levels of vitamin E (100 and 300 mg α‐tocopheryl acetate/kg diet) for each lipid source (FO100, FO300, LO100, LO300, SO100, SO300). The juvenile Chinese mitten crab, Eriocheir sinensis, respectively, fed on these diets with four replicates for 6 weeks. The crab weight gain (WG) and specific growth rate (SGR) were significantly affected by dietary lipid sources. No difference was found between the crabs fed two levels of vitamin E, but the WG and SGR were numerically higher in crab fed 300 mg/kg vitamin E than those fed the other level of vitamin E. The lipid source and vitamin E level could affect fatty acid composition in the hepatopancreas. The contents of saturated fatty acids (SAFA) and n‐3HUFA were significantly higher in the crab‐fed fish oil. The highest contents of n‐6PUFA and n‐3PUFA were found in the crab‐fed soybean oil and linseed oil respectively. The contents of SAFA, n‐3HUFA and n‐3PUFA were higher in the 300 mg/kg vitamin E treatment. A lower malondialdehyde (MDA) content and higher phenoloxidase (PO) activity were observed in the crab fed 300 mg/kg vitamin E. The results of this study indicate that the Chinese mitten crab fed the diet with 6% fish oil and 300 mg/kg vitamin E showed better growth, antioxidant capacity and resistance to Aeromonas hydrophila.
