“…In our study, the amount of GPx did not change. Similar to our study, the GPx activity of shrimp fed a diet enriched with 0.01% herbal extract did not show a significant change in the 2nd and 4th weeks of the trial (Harikrishnan et al, ; Harikrishnan, Balasundaram, & Heo, ; Harikrishnan, Balasundaram, Jawahar, & Heo, ). In other studies, the effect of natural feed additives increased GPx levels in the liver (Elabd, Wang, Shaheen, Yao, & Abbass, ; Hoseinifar et al, ), spleen (E. Yilmaz, ) and skin of fish (Hoseinifar et al, ).…”

In this study, carob (Ceratonia siliqua) syrup was supplemented in the diet of tilapia (Oreochromis niloticus), and its effects on growth performance, immunological and serum biochemical parameters, gene expression responses and ammonia resistance of the fish were investigated. Carob syrup was added to the fish diet in ratios of 0%, 5%, 2.5%, 1.25% and 0.625%, such that five different diets were prepared: control, Cerat5000, Cerat2500, Cerat1250 and Cerat625 respectively. The fish were fed with experimental diets for 60 days. The survival rate of fish fed with 5% carob syrup decreased compared with all other experimental groups. Thus, this study found that feeding tilapia fish with 1.25% carob syrup for 60 days increased gene expression responses, some innate immune parameters and ammonia resistance of the fish without negative effects on growth performance or serum biochemical variables.

“…Several studies also showed the anti‐tumorigenic, anti‐proliferative, anti‐bacterial, anti‐viral, and anti‐parasitic properties of green tea in laboratory animals and human (Cabrera et al, ; Crespy & Williamson, ). Although the application of green tea on growth, immunological and biochemical parameters and disease resistance in some fish species has been shown (Abdel‐Tawwab, Ahmad, Seden, & Sakr, ; Cho et al, ; Harikrishnan, Balasundaram, & Heo, ; Hwang et al, ; Nootash et al, ; Sheikhzadeh, Nofouzi, Delazar, & Khani Oushani, ; Thawonsuwan, Kiron, Satoh, Panigrahi, & Verlhac, ), little information is available on the protective role of green tea against different oxidative stresses in fish species (Hasanpour, Salati, Falahatkar, & Azarm, , ; Sayed & Soliman, ). Therefore, in this study the protective role of GTE against depletion of immunological and antioxidant defenses imposed by dietary oxidized fish oil (OFO) of Siberian sturgeon were evaluated.…”

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.

“…Many reports indicated the role of immunostimulants in increasing the resistance to fish pathogen infections by enhancing non-specific and specific defense mechanisms [35]. Immunostimulants such as green tea-supplemented diets significantly increased the complement activity [14], and oral administration of glucan significantly enhanced serum complement activity in seabream [36]. We found that the recombinant epinecidin-1/DsRed fusion protein inhibited the growth of a broad spectrum of bacteria at <400 mg/ml in vitro and inhibited bacterial numbers in vivo.…”
