“…This is supported by study on, Clarias gariepinus, fingerlings enhances the hematological parameters even at a low level (0.5%) incorporation of garlic peel in feed and resulted in highly immunecompetent and more resistant to infection by A. hydrophila (Thanikachalam et al 2010). Moreover, decaffeinated green tea in lower doses (20mg s/kg feed) of administration could be optimum to enhance the immunity of rainbow trout (Sheikhzadeh et al 2011).…”

The most common strategy to treat in aquaculture disease is the use of antibiotics, however, such utilization has been accounted to have antagonistic impacts like accumulation of drugs in tissues, development of drug resistance and immunosuppression. One of the most promising methods of controlling diseases in aquaculture is strengthening the defence mechanisms through therapeutic administration. Vitex trifolia, Strobilanthes crispus, and Aloe vera have been reported to have better antimicrobial activity in vitro against Streptococcus agalactiae. However, there is no report on the application of the extracts on the treatment of Oreochromis sp. The objective of the study was to assess the effectiveness of diet supplementation of selected plant extract for 14 days as disease treatment. In red blood cell (RBC), haemoglobin (Hb), mean corpuscular volume (MCV), white blood cell (WBC), alanine transaminase (ALT), aspartate aminotransferase (AST), and alkaline phosphatase (ALP) showed significant differences between treatment and control. RBC, Hb and WBC levels of the infected group were significantly higher (P<0.05) than those of the control group indicating improve defence system in the fish fed with V. trifolia, S. crispus, and A. vera. These results suggested that of methanolic mixed herbal to applying S. agalactiae infected Oreochromis sp had a synergistic restorative effect on the haematological variables.

“…There are limited reports that diet containing GTE resulted to enhancement of immune function in rainbow trout (Sheikhzadeh et al, 2011) and tilapia (Abdel-Tawwab et al, 2010). Thawonsuwan et al (2009) found that Epigallocatechin-3-gallate derivated from green tea could enhance immune function in rainbow trout.…”

“…Green tea as food additive in fish diet had been reported to increase disease resistance, improved survival rate, growth rate, stress responses and antioxidant system (Cho, Lee, Park, Ji, Lee, Bae, & Oh, 2006;Abdel-Tawwab, Ahmad, Seden & Sakr, 2010;Sheikhzadeh, Nofouzi, Delazar, & Oushani, 2011;Ebrahimi, Salati, Azarm, & Hasanpour, 2015). Main compositions of green tea, a product that made up from leaf and buds of the plant Camellia sinensis are tea polyphenols, vitamins, nitrogenous compounds, caffeine, inorganic elements, lipids and carbohydrates (Ebrahimi et al, 2015).…”

Effects of green tea in fish based oxidized oil was evaluated in this study. Lipid of diet was replaced by oxidized fish oil (OFO) at 0, 50 and 100% levels. Green tea extract (GTE) was added to diet in 3 levels, 0, 5 and 100 mg/kg giving a total of 9 experimental diets. Two hundred and seventy sturgeon hybrid (Huso huso ♀ × Acipenser ruthenus ♂), mean weight of 211.71±0.23 g randomly divided in 27 fiberglass tanks with 700 l volume after 2 weeks adaptation. After 6 weeks, biometry was done to evaluate growth performance and blood samples were taken. The result showed that feeding with OFO had no effects on condition factor and specific growth rate. However, in fish fed GTE feed efficiency ratio and protein efficiency ratio improved slightly. Red blood cells were not affected by OFO and GTE while in fish received GTE and both GTE and OFO white blood cells increased significantly (P<0.05). Immunological parameters, (IgM, ACH50 and Lysozyme) showed significant increase in compare to control (P<0.05). Our findings showed that feeding of sturgeon hybrid with OFO had no effects on growth but GTE improved feeding performance. Also OFO had no effects on immune function.

“…Previous report that decaffeinated green tea can enhance immunity of rainbow trout (Sheikhzadeh et al, 2011) and that catechins increased nonspecific immunity in grass carp (Sun et al, 2012). In the present study expression of these nonspecific immunity response related genes, GSH-Px, hsp70, MTA and ubiquitin, were not significantly affected by GT compared with BD, while expression of hsp70 and ubiquitin in hepatopancreas of fish in GTW significantly increased compared with BD, suggesting that grass carp in GTW had higher immune ability to overcome stress, which was in line with previous result.…”

To investigate the effects of green tea waste on growth and health of grass carp (Ctenopharyngodon idellus), Green tea waste (GTW) and green tea (GT) were added in the basal diet (BD) of fish by replacing wheat at an inclusion level of 5% to form three diets. 60 grass carp (43.8±2.8 g) were divided into three groups (each group having two replicates) and fed for 66 days. After which growth and health of fish were determined. The results showed that final weight of fish and feed efficiency ratio in GTW group were between BD and GT groups and they were not different compared with BD or with GT groups. Expression of muscle myf5 and myf6 in GTW were between BD and GT group, being significantly lower than BD group. Serum TP, ALB, GLO, HDL, LDL and T-AOC in GTW group were significantly higher than BD group. Expression of hsp 70 and ubiquitin in hepatopancreas of fish in GTW group were significantly higher than BD group. The results suggest that GTW supplementation has positive impact on health of fish without affecting the growth of fish.
